Robimo wheel transport independently

Why choose all models? For the cob varto is appointed for this, as we can see the result of such goals, we want to reach for the help of transport. You can come up with a special set for an electric bike - you will definitely ask for all the work from the selection. But more importantly, what is necessary is that the unit itself is made of a fabricated frame, on which you can put an electric motor.

You can find the necessary details and accessories at retail stores, wine shops, and markets with technical goods. Do-it-yourself electric bike for 30 quills to get a whole lot of strength for a schoolboy stuck through.

Main components

Call for a 48 volt engine, a small bicycle, some kind of yoga, three tools and a fastener. And also patience and guilt, readiness to technical testing.

Dodatkovo get to know:

special controller from programming management;
acid batteries for the living system;
disk galmo (2 pcs.) rotary type, mechanical;
moped lanceug;
"Zirochka" for 13 and 66 teeth;
jumpers;
zabіzhniki;
fastening for the engine from stainless steel.

Deyakі miltsі vvazhayut for better pick up a folding bike, which in seconds can turn into a vantage bike or fit in the trunk. Razbіrny variant zruchny for no particular reasons - changes in the size of the wheel, ease of transport at the lift.

The essence of the modification is based on the split frames, to which the successful knots are welded in two places. The stench is fixed with special bolts, screws and the procedure for choosing and arranging the unit in each case takes less than 1-2 fibers.

Vibir dviguna

A self-contained electric bike has a built-in high-tech technical overhead, as an easier m'yazovі zusillya. The main element of the current design is the engine. It is necessary to choose yoga up to the required voltage and strength of the struma. With this, the tension may be in the region of 400 watts, then it will be possible to reach the speed of up to 30 kilometers per year for the presence of the reducer. The travel distance can reach 30 kilometers, depending on the pressure of the battery.

Before choosing a model, it is important to balance the balance between the voltage and capacity of the battery and the voltage and capacity of the engine. For example, when choosing a 500 watt motor and 12 volts, a battery with a capacity of 40 amperes per year is required. Permissible єmnіst rozrakhovuєtsya by Ohm's law. With a normal discharge, the battery will last longer and longer. To save energy, it’s better to scatter with m'yazovy force, standing on the pedals - you can save energy on the level of the coefficient 1.2. It’s better to charge more foldable carts for a change of time: on the hillock and the mountain, on the dirt road.

Adjustment of the resistor

The electric bicycle is tricycle or two-wheeled, however, it does not affect the visibility of the gas handles. The replacement version of the resistor helps to change the speed of the change and the number of wrappers of the engine. Razrahuvavshi tightness snake struma, take a suitable attachment from the necessary tension. Contacts are installed on the handles of the galma for switching - the station is closed, passing the electrician through the lance. The onslaught on the contacts gives rise to the stuttering of the lansyug - the dvigun zupinya or speed up the robot.

Call the standard dial of the electric bike to find the necessary details for folding. The head of the majstra zrobiti so that the dvigun zupinyavsya when pressed on the handle of the galma. For this, take two aluminum pieces. One is installed on the shabby parts of the pebbles, the other - on the non-shattered ones. The rise of the first day in the opening of the lance of the engine, which is fastened to the brackets with a zvaryuvannya way, gives a functional electric galmo.

Scheme development

To pick up an electric bike with your own hands for 30 quills, you need to at least reduce, but also obov'yazkovo knowledge of the current laws of physics.

For example, Ohm's law, opir materials or electrical conductivity of various speeches. sklavshi simple diagram Vіdpovіdno to classic technical support, it is possible to spot gaps in the design, causing possible malfunctions or the possibility of further modification.

The scheme of an electric bicycle includes the following elements:

bicycle body;
jerelo struma;
dvigun;
replacement resistor for introduction at the opening of the lance;
battery.

Various schemes allow you to improve the wines and drive the transport to higher speeds with the same battery.

Selectable controller

The head of a classic electric car is the presence of a special regulating building. This is a controller for an electric bike, which is a box that manipulates the traction of the entire unit. Like in the country, there is an exchange of clothes for a bicycle, which accessory will help you to set a limit for an hour of travel. Mostly 25 kilometers per year.

The design of such a sensor is not available in the warehouse of electrical panels.

Ale is the processor, which is the source of the magnets of the wheel rim. The controller allows you to optimally distribute the tension on the wheels, speed up the sight of heat, and the engine - to normalize the speed and change without rivkiv.

Vibrable algorithms help to crash evenly and with the same speed.

Operating rules

Today it is possible to have sufficient transport costs, chosen by the people, in the light of the day. There are mountainous convergences, unsafe tricks, gorges pierce. Ale, you can just take your satisfaction from seeing a good, reliable car, as if you were taking off another similar engine.

It is important to take into account the technology of making an electric bike with your own hands for 30 quills, but it is no less important to put yourself up to the recommendation of how to choose the right one for the transfer.

It is not possible to permanently overvoltage the battery due to the relocated wiring installed in the engine. Also, do not put the bike on the sun - the battery can overheat and use up to 80% of its capacity. Particularly unsafe temperatures are close to 40-45 degrees near the scorching lands.

An electric bicycle with a hand for 30 credits can be paid fine. Vіn serve a lot of rokіv, yakscho dotrimuvatsya zahodіv zhodіv and competently follow all the recommendations.

Otzhe, mi z'yasuvali, like a self-sufficient foldable electric bike. Like a bachite, at whom there is nothing folding.

Today we will talk about those who independently chose an electric bike with their own hands at home minds. We also know how to transform a simple mountain bike onto an electric bike for the help of an electric wheel - photo and instructions

How to make a choice with your own hands on the basis of the simplest bicycle, an electric bike can have a small engine, which successfully moves forward. It can be said that it is the most low-powered, but all the same transport. Slowly, in the presence of the exhaustion of the engine, which is induced by the vibrator, as it is pumped out from 150 to 1000 W, an electric bicycle can slightly ease the pedaling for unprepared riders, or take all the burden on yourself. The truth is, the speed of shifting a bicycle with a motor, in a pair of stars, did not increase much. The reason for which rule road traffic, scho pod_lyayut all transport costs for categories

Wanting, insanely, to know the smart people who create self-reliant electric bikes and with thicker motors, developing a speed of 120 km / year for their help and getting up to the girka without help. Before speech, folding an electric bike with your own hands is no less popular (or even more) than factory assembly. For those who want a little bit of technical know-how, there are special kits, which include the main components for equipping a simple Russian driver: an air motor, a battery and a charger for a new one, as well as a control controller.

Detailed video for choosing an electric bike with a motor-wheel set:

The only thing is the power of an electric bike, which is not directly folded (with one's own hands or with a factory one), for someone who does not have any difficulties to charge the battery, and who has an electric socket next to him. So, just like a mobile phone, a bicycle can be left to charge for nothing, a few years to charge for those who are ready to “work” in the morning. And how buti, how is the battery siv at the door? It's okay, pedaling the old way, you can get to the point of recognition. See the electric drive for bicycles. It doesn’t matter: choose a bike on the basis of assembly or with your own hands in your home minds with the choice of such ready-made kits, like the “Electric Bike Conversion Kit”. head detail, sho priyaє ruhu such bicycles without zusil from the side of a person - a great electric drive. Moreover, there are sprat types.

The greatest extensions and recognitions are among the numerical coristuvachiv for noiseless work - induction of engines. This is the case, if the motor is fastened either to the front or rear, or to both wheels of the bicycle, not in the same way as the road looks like a transport problem, but rather tight-fitting. A wheel with a motor is good, because it can be 150-1000 W thick, and at that it does not require great losses for installation. The electric drive with a lancet is more galaslivy, but less important, yet more practical, the shards of a lot of self-sufficient people have learned how to stop motors all the time. butovy electric appliances for folding wet electric bike.

The tightness of such an electric drive, the ability of a different box to work effectively, and to finish the ride with a swede. It’s a pity only, the variety of ready-made components is higher, lower in the first type of motors. The roller of the friction electric drive of a bicycle is less suitable for its installation: it is not necessary to disassemble the entire structure. Installed in the fire of the wheel. Turning, the roller transmits the torque to the wheel, to which the wheel begins to crumble. Friction electric drive may have a large number of minuses in relation to other types of motors. The coefficient of power of such an engine is richly smaller than the others, and the high varity and quick wear of the wheel tires make it an unacceptable option for buyers. Before that, the system functioned normally, it was necessary to constantly press the vise in the bicycle tires, but not manually.

The benefit of this set is that you can easily convert your favorite bike into a bike with an electric motor for the help of other components. You will be left with less to install that spare electric dialer for full-time work. Let's take a look at the details of the electric bike and what is necessary for the operation of the electric bike:

1. Easier - your bike is taken as a basis with a different wheel diameter - 20, 24, 26 or 28 inches.

2. An electric wheel for a bicycle is a brushless electric motor for a bicycle. fast strumu, a kind of fastening in obid. Vіn can be installed like in front, in the back, so up to both wheels in a row - all-wheel drive. For the tightness of electric motors for a bicycle, they can be like this - 250 W, 380 W, 500 W and the most powerful dvigun wheel 1000w (for example, 500 W building speed up to 45 km / year, which is already not enough). The whole motor does not need regulation, adjustment and maintenance.

3. Rechargeable battery - the battery is another important part. Vikonuє function of giving a jet from the accumulator to the electric motor. Batteries are available at 12, 24, 36 and 48 volts. If you want to see how much the battery is getting tighter, it doesn’t mean that the battery is getting worse. It is recommended to choose the battery according to the voltage of the electric motor. Buy LiFePO4 batteries (lithium phosphate batteries), stinks of stink can be so good - cheap, reliable, durable (on average 1500 charge-discharge cycles), easily charged (approximately 2-3 years). Charging attachment for such accumulators it is easy to charge and guess the best charging for mobile phones.

4. Special kerma handles (speed adjuster) allow you to adjust the speed of the electric bike.

5. Controller - a block with different wires, which is responsible for the operation of the entire electronic mechanism. Є with a payment, as it is ripped in an aluminum case for the protection of the zovnіshnіkh vplivіv. Same best place for the new one, a flask holder.

6. A pouch or a bag for a battery for storage of batteries.

7. Rіznі droti and zapobіzhniki - for the work of the fortune-telling points. It is possible to vikoristovuvat and zvichaynі droti vіd аudіo columns.

Advantages of self-built electric bike:

1. As a ready-made "wheel motor" kit, you can install yoga on your bike for less than a year.

2. For the price of electric motors for bicycles, it will be significantly lower, lower the purchase of a ready-made, selected electric bicycle;

3. The finished electric bike will be very important for the account of standard parts and the simplest batteries; .

4. The finished electric bike will be a little tighter, so if you want to choose an electric bike yourself, you can choose the components that will tickle you, individually.

We have brought only a few arguments, to help you with a choice, prote in order to independently choose a working mechanism, you need to understand electronics.

The main feature of an electric bicycle is the presence of a motor, a battery and a controller. Nasamkinets would like to sprout visnovok about those that the impact of such an electric bike can be more positive.

Do-it-yourself kit for an electric bike is folded from a previously selected wheel, a controller, a gas handle, galm handles, a pedal sensor, a headlight with a lock, a horn button, a bag for the battery.

Another part of the kit is the battery and the charger.

Kits are available for 12, 24, 36 and 48 volts and 250, 380, 500 and 1000 watts.
The battery is selected according to the voltage. I'm glad to be not chasing for hardship. 380W is enough for even and humpbacked masses. More tightness, speed will not be significant, but it will be better to “pull” uphill.
My special dosvid- I rarely help with pedals and stars to stand for the whole hour at the "maximum speed" position.

Varto respect that rich countries have 250W electricity.
Why I chose 48V, I can’t say for sure at once, but in the grass, if I searched the Internet, a mark was placed before buying a bula - take only 48V. With the exhaustion of the battery, everything is simple - I have 10A, tse 25 km. If you buy 20A, you will travel 50 km and 16 kg of battery instead of 8. Verishit, why do you need to carry 4-8 kg of weight, so you don’t go far. I understand that tension is not measured in amperes, but sellers separate them. Chi is not wat / godina, but the voltage / ampere itself.

Motor for self-propelled electric bike

Wheel-motor 4 already selected. The camera cover is not included. The wheel needs to be selected according to the size of the wheel of your bike, for me the number 26 is the widest size. If you bought a camera or a tire - you know for sure.

Golovna, scho need to remember, mounting the wheel - the cable is guilty of coming out of the wheel of evil! Then it will turn around in the right book. Another and not obvious problem is that three darts and thin sprats come out of the wheel. The first thing to do is to rob a person by mounting the wheel - to turn it. The wheel vibrates the electrics, between the power wire and one of the thin wires, a spark slips and everything, after the sensor is on, the coils are swayed. Therefore, when the wheel was out of the box, it was wrapped around with electrical tape and until the moment it was connected to the controller, it was so.

It is possible to get a little bit of a landing on a fork and all on a wheel, it happened to me. The dremel pulled out that sprat of cutting disks to install the wheel.
Here you need to be as accurate as possible, so that the larger wheel sits in its place, there will be fewer problems in the future. Don't waste your money. To the owners of expensive bicycles made of aluminum forks, varto vibrate the rear wheel, I read that the wheel was tighter and the wheel simply vibrated on the wheel when the test was turned on. The front fork is designed to go uphill and back, and the wheel is pulled forward along the stake. And the axle of the motor on the rear wheel gives a grip on the frame, which does not rip off the pedals.

Electric bike controller

Controller - a small aluminum box 3. with a bunch of darts. There are no special problems from it. Find a better place on the frame and close it. Far away on the lower beam, I saw two bolts just screwed into the frame. On one of them, I hung the controller, the other did not bend and I fixed it with a plastic strip. Varto stock up on them, indispensable for fixing cables. One respect. Through the legislator of the exchange of security in some countries, the controllers have been blocked. The most common wire, which you just need to open. Blocking the controller will not give rise to swidshe for 25 km / year.

First, you need to replace the galm handles. I did not take the handle of the front galm. Having replaced the rear. What needs to be changed? At the handle there is a contact, which turns on the electric motor at the moment of galvanization.

In another way, on the left side of the kerma, you need to install the throttle handle. Znіmaєmo gumovu handle, vіdrіzaєmo її іz vnutrіshnої side to nebhіdnu width. We put everything in its place.

Thirdly, you need to install the headlight. At the headlight there is a "lock zapalyuvannya" and a sound signal. I didn’t turn on the sound signal button, I can shout like that. And the axis of a pair of keys made me happy. The key replaces the life switch, and a further turn turns the headlight on. It's manual. Win the key from the “fari” without turning off the bike, do not go into it. It’s important to finish the bike, but walking on the pedals is not so simple (even if it’s stink to stand at the maximum and you still need to crank the engine, like a generator at this time) - it won’t be so easy to tie and roll the villains on your bike. Navit just shake yoga in your hands. Tse allows you not to “stretch” too much, letting the bike ride on a sprat of whiplin and not fastening it with a lock.

Light in the theory of guilt shows the level of battery discharge. Possibly, on lead it is so і є, but on LiFePO4 batteries it does not work. A new charge shines on the back, then a red light - an empty battery. In addition, this superlight is light and stinks corny to stick the night right in the guise, that day you also deserve it. That is why there is a woman of sticky paper. Then I’ll grind the tips of light and drip the beast on the spotted hot glue, so that I can just take off the matte light.

Battery of an electric bicycle, selected independently

A different type of lithium battery. LiFePO4 is cheaper than its brothers from stylish telephones, do not vibrate, good luck great strums, which is easily charged, can take up to 1500 charge-discharge cycles to an ear of a significant decrease in capacity. Such batteries have appeared less than a couple of times ago, and there are still few on the market. The Chinese themselves choose from the last few elements of the necessary voltage, tension and expansion. Krіm batteries in the bag there is a charge-balancer charge. From here, there is a bunch of darts near the battery itself. That is why the battery is charged in parts and around the "banks" of the elements are balanced among themselves.

Why is a lead-acid battery not suitable? Similar to the parameters of my battery with a capacity of more than 20 kg. There will be a battery with electricity, long-term charging, the number of charge-discharge cycles is not more than a thousand, but more than a hundred or two. Not only that, I’m going to buy such batteries in my store - it’s not much less costly. So I don’t guess for pennies.

The motor-wheel is a brushless electric motor of a standing strum. Yogo construction does not have shields, but rather to break electric car more superfluous, and to replace the collector, a sprig of Hall sensors was installed.

The wake-up winding is replaced by permanent neodymium magnets, which, on this day, are considered one of the toughest permanent magnets. The rotor of the design is made of high-grade electrical steel, which makes it possible to work with the KKD design more. The motor-wheel has a non-destructive rotor (which is attached to the axle of the bike) and a stator that wraps around. Selecting the motor-wheel, then analyze, for which purpose you need an electric bicycle, and you should choose the type of required tension.

There are two main control methods for electric bicycles: behind the help of pedals, there is a mechanism for regulating the tension. How to call an electric bike for help in pedaling, helping you to wrap the pedals and help you sing physical sounds. When choosing the method of regulation, the sensor of the (steep) moment will control the speed, or necessary tightness electric motor. Everything is automated and it doesn't need to think about anything - just sit at the seat and go. Some e-bikes have an immature fit, while others may have more than one tension adjustment. You can set up the necessary help in pedaling. With weak adjustments, the ice will help in pedaling, but it will help to increase the hour of the work of the engine. In case of strong lashings, the tightness is more pronounced and you can reach even higher speeds, which at once in pedaling you will help the motor to your own tightness.

On the other side, the mechanism for adjusting the tightness of the flare does not affect the wrapping of the pedals. Just like on a motorcycle, in order to control tightness and tightness - it is necessary to turn and trim the throttle. You can pedal in parallel, but it's not obov'yazkovo.

Some electric bikes are only used for additional wrapping of pedals, others may have a tightness regulation mechanism, and in others there are insulting mechanisms. As a rule, bicycles for help in pedaling may be impersonally forced to work, for which it is possible to choose on occasional trips, and electric bicycles with both mechanisms of regulation may be necessary to assist in pedaling. On these bikes, the final control is ensured by the mechanism of regulation of tension (if necessary), and the additional help in pedaling may have a different meaning - on a equal footing.

Check two different configurations of the motor-wheel installation - front or rear.
Front mounted motor-wheel. Front-mounted hub motors can be found on pre-built or refurbished bikes. If you are overridden by a standard bike, then the simplest solution would be to install the engine in the front, so that in this case you will not have problems with changing the speed or the lance. Most of the conversion kits for electric bikes include batteries that are installed on the trunk, then the replacement of the bushing motor in the front will change the bike shaft and improve the curing.

Since there is a small risk of destroying the front fork with an electric motor, it is recommended to use the bushing motor on the front wheel only with a steel fork. For ready-made bicycles, this is not a problem, because the sound of motors and combined with steel forks and the stench is not so hard.

Hub motors, mounted on the rear wheel, wider is more important on finished bikes, since it is not important to install the motor in the rear at the factory. And the axle to change the bike with a rear motor-wheel is three times more foldable, lower at the front with a front bushing motor, the shards blame problems with the lance, transmission and gear shifting. Plus, you can buy a 6- or 7-sweet trip. But the motor on the rear wheel provides more torque to turn, and not so much as on the front wheel. .

The battery is the most important factor that contributes to the overall performance of an electric bike. Use different types of batteries that are available in different types of batteries. As a rule, ready-made electric bikes are equipped with sealed lead-acid and lithium-ion batteries. And in the conversion kits of electric bikes, there are also other types of batteries. Three main battery types and subtypes that you need to know about when choosing an electric bike:

Sealed lead-acid (SLA) batteries are the most affordable batteries, but they have the lowest operating term and most important. Such batteries are good for beginners and cyclists who are surrounded by financial possibilities. If you fail to buy an e-bike conversion kit, you can install sealed lead-acid batteries on the fly and then replace them with more expensive ones. Approximately on the skin 12 V, the battery voltage increases by 3.2 - 3.6 kg (x2 for 24, x3 for 36, x4 for 48 V). Lead-acid batteries are heavy. The stench is insured for 300 - 500 charges (1 - 2 years of operation). These batteries are more sensitive to the charging process and can be damaged, thus recharging them more, lower by 75%. Crimea, until the end of the operational period, the stench will change the exhaustion.

Nickel-metal-hydride (NiMH) - these are good batteries at an affordable price. The stench is less and lighter. They have a longer period of operation, lower for lead-acid ones. Quite frankly, as most of the ready-made electric bikes have become equipped with lead-acid and lithium-ion batteries, nickel-metal hydride batteries are equipped with only conversion kits, for the help of which you can independently convert your bike into an electric bike. NiMH-batteries should be used approximately twice less, lower than lead-acid, and serve 2-3 times more - 400-600 charges (2-3 years of operation). Also, for this type of battery, the pressure does not decrease during the last period of operation or before the residual discharge.

Lithium-ion batteries (Li-Ion) have the longest period of operation and the lowest battery, even if you want stinks and more expensive ones. Lithium-ion batteries are the main name of the great group of batteries. If you are not aware of the types of lithium-ion batteries, then you can spend on cheating at some stores or on websites, if the sellers of the virobniks change their parameters. Types of lithium-ion batteries:
Lithium-cobalt batteries (LiCoO2) are stuck in laptops, mobile phones and a little wider for electric bikes. Even lighter, but more unstable and unsafe. Skhilni to self-employment!

Lithium-manganese batteries (LiMnO2) are the most widely used lithium batteries used in e-bikes. The LiMnO2 battery may be called "lithium" or "lithium-ion". If another specification is not indicated, then, more than anything, it is possible to use the same lithium-manganese battery. Prices available for the price of mid-lithium-ion batteries. I want to stink significantly less, lower types of batteries, stinks more important than the middle lithium-ion ones. If it’s tough enough that the stench will show over 1000 reloads, then don’t lie! Tsey type Lithium-Ion batteries sound like 500 - 800 charges.

Lithium-polymer batteries (LiPo) are three times more expensive than lithium-manganese batteries, but they have similar characteristics. The stench is mainly reinforced by the construction, so that lithium-polymer has no hard metal shell, and only soft polymer.
Lithium-Phosphate Batteries (LiFePo4) The Best Lithium-Ion Batteries! They have the longest period of operation and the least amount of available options! Lithium-phosphate batteries are the most expensive, but they last up to 1500 - 2000 charges and they have the most stable schedule in the range of all possible batteries, which means that they do not lose pressure during the last period of operation until the next discharge.

The battery voltage of a self-propelled electric bike.

As a rule, electric bikes run on voltages of 24, 36 and 48 V. As a rule, the higher the voltage, the higher the maximum speed, although you don’t want to (reverse passport data). Swiftness and speed can be influenced by the efficiency of the motor and transmission, then an electric bike with a voltage of 24 V can have the same maximum speed, like a bicycle with a voltage of 36 V. However, it is a common law that bicycles are more high tensionє shvidshimi. At 24 V, the maximum speed can be 24 - 29 km / year, at 36 - 26 - 32 km / year, at 48 - 39 - 45 km / year.

If you want these characteristics to be beyond the standards, assigned to the law, but also the conversion kits for reconditioning can inspire a mother of 72 and develop a speed of over 56 km / year! But such a high level of speed can mean a lot of attention to the components of a bicycle. Worry that the most recent athletes will increase the price of a bicycle from an average speed of more than 27 - 29 km / year. 32 km/year is given even higher speed for more cyclists. Everything that is greater for the sake of security is unsafe and violates the law. In addition, the higher the voltage, the more batteries are installed, which means the higher the price is the mass.

The place of batteries in a self-propelled electric bike.

Batteries are rated for voltage (V) and per ampere-year (A * year). Pressure is added to the greatest respect, but not less important and ampere-year-olds. In ampere-years, the battery capacity is reduced. Vaughn is a good indicator of the number of kilometers, which can be passed on one battery charge. If you want to pour in, you can also have a lot of other factors: the cyclist’s gait, the weight, the tightness, the efficiency, etc. Also, on average, a statistically average cyclist with a 10 A*year battery can travel 16 kilometers (without pedal wrap). And if a cyclist pedals, then the number can be significantly greater, so more batteries for 10 A * year are estimated by virobniks, taking pedal wraps to their respect, like "you can go up to 32 kilometers."

For bicycles, which can help with pedaling, the range of tightness is estimated richer. It is through those that the cyclist gradually helps the engine and thereby lowers the strum (tightness).

Tim is not less, we believe that the tight electric bike is the personal transport of the future, which is gaining popularity. Mayuchi all practical advantages and speed of the scooter are more universal and passable, maneuverable, noiseless, environmentally friendly, cheap to operate. You can take an electric bike at home, for it you don’t need a garage or a parking lot, which is protected, like for a motorcycle or a scooter, which can be safely left on nothing on the street.

This article talks about how you can turn the best bike into an electric one with your own hands. Such a bicycle is ridden on a battery, which, when charged, can be recharged and then driven away. Obviously, there are already a lot of ready-made solutions for similar self-sufficiency, for example, a motor-wheel, but here everything is taken from scratch.

Behind the words of the author, the self-confidence completely proved its hopes. Since the engine here is not too hard, then you can’t destroy the bike for a month, it’s necessary to kick it with your feet up to speed of 10-15 km / year, which is not so easy. And then an electric motor turns on in the room, which supports the movement of a bicycle and it is no longer necessary to turn the pedals. The electric motor roams the bike up to 34 km/year per hour in a straight line.

Keep the bike running for an hour on a straight road 100-300 watts. In Russia, the uphill climb grows up to 600-800 watts, to save, you can help with your feet.

Peak adjustment of the struma by the engine made 1200 watts.

Materials and tools for choosing self-confidence:
- electric motor type 6354 kv200

- speed controller ESC

- Wattmeter (copy of Turnigy 130A);

- battery type LiPO 6S 22.2V 5a-h;

- throttle handle like a bicycle (checked with the thumb);

- galma handles (they have a pressure sensor);

- Rear trunk (vicariously as a structural element);

- triskachka 16 teeth;

- gears of the wheel and belt (ready).

Bicycle modernization process:

Croc first. Installing a zirochka
Most often, the zirochka is creased to the knitting needles, but the author virishiv moves in such a design. At the result, the bula was screwed to the galvanized disk for additional bolts. On the disk, you can also strike six guilds for a stake, and two closer to the center of the galvanic disk. Tsі gvinti fixes the cut, so that the disk does not twist when driving.

Croc is different. We install a treble
The treble is installed on the cups in the form of the carriage, for fixing the vikoristovuetsya ring in the form of the right cup.

Crook the third. rear hub
The rear bushing protrudes from the role of the intermediate shaft. Vaughn is installed near the profiled pipe of the U-shaped form.

Crook quarters. Installation of the great cogwheel
For fixation of the gear wheel, a pin is fixed. Otherwise, the sleeve itself is tucked into cones. The gear wheel has a groove, and the pin is inserted into the opening that is near the shaft. As a result, the pin lies against the groove of the wheel.

Krok five. Male gear wheel
To fix a small gear wheel, vikoristovuyut two tugs.

Krok is the best. Installing the engine
For the fastening of the engine, a standard crossbar is used to an L-like design, as the author found in the locks.

Croc somiy. Mitsny natyaguvach lansyuga
The tensioner of the lancet is attached to the side element of the trunk. Everything is installed on a structured plate, made from a thick aluminum sheet.

Biker look

Krok eight. Wiring diagram samorobki
How the scheme is improved, you can look at the pictures. Vaughn bula trohi redone with the original. So, for example, a change resistor was tidied up at the servo-tester, and a cold sensor was installed on the same space with gas control knobs. At the lancets of the button, the author, having installed a resistor support of 1 kOhm, without a new moment, the modes mimicked, even through guidance.

Another nuance of the electrical part is that the author has a difference in life plus vimiryuvalny plus. Also, in the future, it is a sense to put an insulating converter 5V to 9V, in connection with this, which is an underestimation of the indication of eating.

If there are batteries, then they won't work without BMS. In order to prevent overdischarging, the author vikoristovuvav battery monitor, some kind of lashing at 3.3 V. If the voltage becomes too low, fix the sound.
The battery is charged by an IMAX B6 clone, the Li-Io mode is reversed from balance.

Technical Director of REG.RU Valeriy Studennikov tried to solve the transport problem especially for himself, and then turned his hobby into a startup.

We would like to present your opinion from the founder of Electron Bikes about those, how to build a tight electric bike with your own hands, why those who love speed do not control the basic models of bikes and to such speed you can build a superb-looking bike.

First acquaintance with electric bikes

In the past, I have tested electric bikes for some time, 2011, at a bike show in Moscow. Dear, inconspicuous, rather weak in terms of characteristics, the scarlet stench has been hooked up, it has appeared to get to the next type of transport. The study of the market at that time showed that it was simply unrealistic to buy a ready-made electric bike with good characteristics for an adequate price. On the market there are either low-power and low-voltage bicycles with a small battery (“weak” in all countries China or expensive, glamorous, but also quiet Europe), or super-expensive monsters, the cost of such a bike starts at $ 100 Electric, Bike Stealth Hi-Power Cycles), some of them also have their own shortcomings (inadequately large shaft through an important frame and an important motor-wheel, weak traction “on the bottoms” due to jamming of gearless motors, a small power reserve).
Ale, the light-weighted bazhannya is silent, light, and at the same time tight, and the electric bike is nowhere to be seen. Tom had a chance to choose the only available option - to choose the bike himself from the components that are most obvious on the market, as if to rob a lot of other enthusiasts.

First Mlynets

The first "lump" was to try out a bike based on a kilowatt motor-wheel MagicPie with a built-in controller, bought in a set with a 10 A* battery for installation on the trunk. Pick up the device in the distance, prote the joy of the new bike, which was broken up to 42 km / year, was unhappy - the trunk under the battery wagon lived for exactly three days, having broken on broken roads. The keratinization and rozvazhuvannya, with such a roztashuvanni battery, also did not quieten much. It was hard for the rear wheel, as it got so bad at the vase - on the windshield in the black hole it was possible to easily pierce the chamber or bend the rear insult.

That is why, during the offensive, the battery, for the help of self-supporting fasteners, migrated to the down tube of the bicycle. As a result, the rosette looked better, but the design looked scary and obscene. For the description of similar wickerwork of smart pens, the veterinary baikobudivniki used the term “shahid-design” to instill fatigue.

On a bike with more correct wiring, it was already possible to ride comfortably, but it became clear that a standard 500 W * year battery (50 V, 10 A * year) for a strained bike is more than an average whistle - electricity can get from point A to point B , and back is already less on the pedals. As a result, a large battery of 1000 W * year (50 V, 20 A * year) was bought, as if the ramie fit into the front tricot, but it happened to be sealed with electrical tape;) Everything looked like this:

The monster, which is viishov, did not wrap the pedals through the width of the battery.

It dawned on me that it was impossible to get rid of it.

It was necessary to use the battery with a battery - change the spacious layout, so that the pedals were not scrambled for it, and sort out the її fasteners, preparing an additional battery box. For vikonannya long searches and the admission of candidates for graduation Oleksandr Kostyuk is a member of the VeloSamara cycling club, who also deeply adopted the idea of designing an electric bike. Looming behind shoulders bagatorichny dosvіd konstruyuvannya that budіvnitstva raznyh prototypіv vosgogo scho tіlka collapses, vіn undertook the task of inspiring boxing. It was done with the help of yogo from AMg sheet (aluminum-magnesium alloy) 2.5 mm zavtovshki, closed with aluminum coils. Boxing fun - powdered. Also, a Cycle Analyst wattmeter is installed on the bike, which allows you to measure a couple of indications, including energy consumption in watt-years per kilometer. With such an attachment, you can no longer worry that the battery can’t be discharged at the most unexpected moment - leather stained ampere-year or vat-year on the rahunka. The result of viishov has this bike:

On such a device, with a handy, manually and superficially fixed battery, it was already possible to calmly ride around the place without a fight, so that you could fall into the most unexpected moment. That one looking at the bike is already decent. Ready buk bike akurat for the winter of 2012-2013 and clearly showing itself in winter minds, including driving and snowfall, and in cold weather and in frost minus 35 degrees.

Just ahead!

After the successful completion of the life of the first apparatus, the idea of continuing the construction of electric bikes at once from Sasha was born. I had a lot of what I wanted, and Sasha had a great design record.
We virishi did not rush at what was attained and the one who Russian market at that time, there were simply no electric bicycles (there weren’t any at the same time), on which we ourselves wanted to ride. Nіsha dosit hard (paired for swedkіst and dynamics with a scooter or a motorcycle) and with a lot of lungs and adequate for the price of electric bikes, it was empty. But low-power bicycles didn’t bother me and Sasha zovsim, even to us, active and young, we wanted to ride “with the wind”, so the bike could have a decent run and an excellent design for riding on Russian roads and off-roads.

It was possible to create a universal electric kit that allows you to transform any modern mountain bike to electric. Hydrobikes were chosen as a base not in a special way - they are even more popular in Russia (they store the main class of bicycles for grown-ups), universal (allowing people to ride both locally and without roads) and above. It is also important that the details and knots of the mountain bikes are standardized, which also allows the standardization of the electrical kit.

It was necessary to choose adequate components for the bike and to complete a whole series of engineering tasks:

Pick up the engine, building to see the great tension and the moment, at which it is easy.
Choose a compact and light battery of sufficient capacity, build a large stream.
Replace the rear wheel dropouts so that the entire high-torque engine does not rotate.
Expand the sensors of the application for hydraulic galms (serial hydraulic galms with sensors only begin to appear for sale and may have their shortfalls), even automatically turn on motor when pushing galm - one of the basic standard vimog for electric bikes. And the mechanical galma is no longer suitable for the characteristics of a safe galvanization on quiet laces, which are small enough for us to reach.
Think over a solution for the life of the front headlight and the rear light (with a signal) from the onboard voltage of the electric bike, transferring the power supply to the windshield.
It is distinguished by high-quality roses (sealed bag), bike computers, wattmeters, lighting equipment and other accessories.

And last but not least - it was necessary to expand a universal box for a battery and a controller for a quick conversion of a superb serial bike to an electric one. The previously chosen metal box was not suitable for this role, the shards required great labor costs in the preparation, that bula was sharpened for the shape and dimensions only for a specific frame.

Podsumkove solution is not enough but simple for installation, technologically and cheap for preparing.

The axis is one of the first stages on this path, boxing of the spring of 2013:

The axis is one of the intermediate stages:

What happened?

As a result, robots and experiments were expanded in a proper universal way and richly aesthetic boxes, electrical kits and bicycles on their basis:

Characteristics of these devices:

speed - up to 63 km/year;
pressure - up to 2.5 kW;
battery capacity - up to 1 kW * year;
driving distance - 40 km per maximum speed(63 km/year) and up to 100 km in the economy mode (30 km/year).

Bicycle chi motorcycle?

The bikes on the basis of the created electric kit were rightly blown, the buildings were completely collapsing in the Moscow flood at a speed of 60 km/year. According to the new rules that regulate the intensity and speed of electric bikes, stench is not formally seen up to bicycles (whose intensity on electric power is 250 W and 25 km / year), nor to mopeds (whose design speed is not guilty of exceeding 50 km / year), and lie down to the class of motorcycles. Whereas old look which bike does not reveal any particular suspicions - a bike that looks great with a box in the middle of the frame. That gear of the device did not increase much, the tight electrical kit adds a total of 14 kg to the bike, as a result, the rail of the finished bike goes into the region of 26 kg. Such a device for a grown-up person can be lifted by force with gatherings, carried through the crossings.

So wiyshov is functionally a moped, but in a bicycle shell. As a result, you can win over both types of transport: we have a bright “green light” for a bicycle (pushed areas, sidewalks, ground and underground crossings, crossings, flyovers, parks, stitches and just roadless), with which the speed and dynamics of a moped are available on the road. scooter (for more, lower for a scooter or a motorcycle for maneuverability) to drive a tight electric bike in the minds of real traffic with the best land transport in the world.

I want the tightness of our standard electrical kits and are already similar to a moped, as a sporting interest and an experiment (not cheap, as it turned out after the price of the vartost of all components), we chose important things and electric bikes on the basis of special Quix frames:

І Ukrainian “Rami Chobotar”:

Tsі 6-10-kіlovаtnі monster building rozdatnі razvitat swidkіst vzhe up to 90 km/year, mayuchi dynamics of a light motorcycle. And when you get full gas, you get up on the goat for a month. A battery of 3 kW * year allows you to travel 120 km on a speed of 40 km / year or 40 km on a speed of 90 km / year, why can you beat such a bike as a long-range foreign transport and for driving on the highway.

What did you give?

The design of the electric kits and electric bikes Electron Bikes continues to be gradually improved. Nezabar will be ready before the industrial serial release of two models of the bike:

"Standard" (on the basis of a standard bicycle frame): intensity 2.2 kW, battery capacity 1 kW * year, speed up to 63 km / year;

Electric choopers (without pedals) "Electro-classic": intensity 6 kW, speed up to 85 km/year, capacity of two external batteries up to 3 kW * year;

І "Electro-bobber".

The rest is also owned by a unique parallelogram fork made of titanium, issued in a limited edition.

Not much about attachments of an electric bike

A few words about the power of the components of an electric bike, as well as about technical folding, how to stand on the path of the creators of a hard bike.

The main electrical components of an electric bike

The "heart" or the m'yazami of the electric bike electric motor(Report about motors and their types below). Modern electric bikes have synchronous brushless direct current motor or BLDC, which allow efficient operation in a wide range of wraps with a high torque. Zrdka vikoristovuyutsya asynchronous motors, like central. (About "Move Shkondina", about how much noise there is on the Internet, you can release some random material;).

"Mozok" is an electric bike - controller. The controller controls the electric motor, supplying at the required moment of life to the windings in a fallow manner in the presence of the necessary tightness of the wrapping and tightness. The controller also monitors all the "logic" of the bike: at the input, the signals are removed from the position of the throttle stick, switching between the modes of operation (you can, for example, in different modes, interchange the speed, tension, or turn on the rear gear), cruise control buttons (even if the auxiliary in the vice mode), signals from the galm sensors (because it is necessary to keep the motor alive when the galm handle is pressed, or turn on the recuperative galm bath with the engine, as it will not be stimulated) then.

Energy for the life of the heart and the brain of an electric bike is stored in battery . The voltage of the batteries of electric bicycles is variable - from 36 to 48 V. Shvidkіsnі devices can be equipped with high-voltage batteries (up to 100 V).
At this time, in the most important place of electric bicycles, lithium batteries are being used (see below for a report on these types), which may increase the energy efficiency. Heavy lead batteries are less likely to be found on found devices.
The battery is stacked with 4 battery centers connected in series/parallel.

The battery also has its own "brain" - the whole battery management system (Battery Management System or BMS). It protects the battery from overcharging, overcharging, overshooting the allowable discharge, and also balancing the cores of the battery, so that the stench is evenly discharged.

To display all the necessary information and the exact amount of calories needed wattmeter, which allows me to say exactly how much energy has been spent and is still gone. A special wattmeter is used in its own functions of a bike computer, including the speed, weather and weather indicators, as well as energy savings per kilometer of the road (W * year / km).

For livelihood of low-voltage alarms (headlight, rear light, horn, repeater) it is necessary to reduce side voltage to the lowest (5, 8 or 12 volts). For which vicory there are highly effective transformations of the post-stroma. DC-DC).

Difficulties of the transitional age

The task of building a heavy bike is folded because the entire industry of components for electric bicycles is at once insured for low-power equipment. The class of tight and swedish electric bikes, which stand on a pіvdorozі to motorcycles, is only shaped, so the creators of such devices on the skin croci have to be vigaduvati.

Batteries

Batteries for electric bicycles, which are serially produced, are usually made up of elements that cannot be seen in a large stream. C-rating (in the case of a battery, as a rule, you can see the battery, up to the capacity of the battery, expressed in ampere-years) of serial batteries, folded, as a rule, from lithium-ion centers, not more than 1, just like other bicycles, like we do, required batteries with a C-rated minimum of 2.5. Tobto, for example, with a capacity of 20 A * year, the building would be able to see a strum of 50 A. With a 50-volt battery, it would be possible to see a pressure of 2.5 kW - a minumum for us. As a result, the batteries are soldered (and at the same time they are charged for additional point charging) independently from the accessories for this element. A search for the results of the examination of the characteristics of the elements, their testing and rejection is also the order of the day. At the same time, vicory prismatic LiFePO4 and LiNiCo cells, which allow the creation of energy-efficient compact batteries.

Main types of lithium batteries

LiFePO4 (lithium saline phosphate). They can be operated in frost down to -30 degrees, an available dry charge for 45 hours, may have the largest number of charge-discharge cycles (1500-2000), allow more tension, fire safety, not combustible. However, it may be lower for the pet, lower for lithium-ion batteries (that is 2 times higher than the battery with the same capacity), but the roads (although the price of operation is lower through a large number of cycles).
We use it as the main solution in kits for hardtail bikes, due to their dimensions they are not suitable for inserting bike-double frames into the front tricot, where there is not enough free space.
Li-Ion (lithium-ionn). Classical lithium batteries, as vikoristovuyutsya mainly for the life of electronics. The stench is the lightest and most, found, can be the maximum for today's pet's capacity (W * year / kg). However, there may be a narrow temperature range of operation (from 0 to +40 degrees Celsius), a small number of charge-discharge cycles (300-400), which does not allow large jets. Qi batteries are most often used in low-power electric bikes, but for hard-boiled devices, the stench is of little use due to the low C-rating.
LiPo (lithium polymer). High energy capacity, may be the same as in Li-Ion elements. Allow high discharge streams, high C-rating. However, if Li-Ion can have fewer charge-discharge cycles (300-700) and a narrow temperature range: when operating below 0, they go out of tune, and in hot weather, they short hum otherwise, mechanical poshkodzhen can be fired. Through my temple, I’ll burn the safety on electric bikes only for fearless enthusiasts.
LiNiCo/LiNiCoMnO2 (lithium-nickel-cobalt). Mayuchi advantages of LiPo (high energy density and building seen great streams), relief of their shortcomings: may have a wider temperature range, and, smut, fire safety. Due to their compactness, they are vikorated by us in electrical kits, which are intended for installation on double-wheeled bicycles.

Motori

But the biggest problem is the creation of an effortless and light electric bike and a motor.
Serial motors are either too low-power, or important, or they may have a low CCD, or they overheat, or at once;)

Motors, which are reserved for electric bikes, can be divided into three classes, the skin has its own few hundred and tense electric bikes.

Gearless motor-wheels (direct-drive)

The force of the magnetic field is transmitted directly to the wheel, which is called direct drive (direct drive).
Nevibagly, nadiyni, to that in them there are no suitable elements, that they wear, krіm bearings. It is allowed to use an electric galm for a recuperative galm bath. Ale, there are two great shortcomings.

The first is a great vaga. For example, a rated motor for 2.5 kW has an average capacity of 7 kg, and a 6 kW motor for 12 kg. Tse is also indicated on the vase of the finished bicycle. In addition, the placement of an important motor in the rear wheel shifts the center of gravity back (the bike becomes handless to wear, perform tricks / stunts on it), as well as increase the "springless mass" of the wheel, which in the first wheel is indicated for survivability, boosting mobility. , tovshchina spoke. At the link with the cym, the wheels with important direct drives often fit into the motorcycle rim, because choose the bicycle rims for the required comfort.

Another shortcoming is low CCD when driving at low speeds. For example, when driving in a mountain, along a ford, a pisk, or I’m off-road, don’t get out of the way, such a motor is very overheated. For example, when driving uphill, a 20% spherical direct drive motor of 6 kW will work approximately 20% of its CCD, and 80% in heat. In such a mode, the exhausted motor-wheel can overheat and burn for a couple of whilins, so it is not turned on at the hour (sound to automatically turn on the motor by a signal from the temperature sensor). It's not surprising: with a weak heat supply in the closed space of the motor, the windings in the low FCC mode are heated by the speed of an electric kettle (4.8 kW heating in our case with a 6 kW motor). Vtіm, if the "teapot" is heated up more, in it you can "pour water" - for example, enthusiasts will solve the problem for help water cooling.

Reductor (geared) motor-wheels

M_styat vbudovaniya planetary gearbox, which may sound like a gear ratio of 5:1. There is less weight for tightness, a larger KKD "on the bottoms" is equal to gearless motors. However, mechanically less overhead (more rough mechanical parts) and do not support recuperative galvanization. Ale, smut, they are not commercially available for tensions greater than 1000 watts.

Central engines (middrive)

Middrive, as it is known by its original name, is the first drive with a high-speed electric motor, which is installed as a rule in the area of the carriage knot, which transmits the susilla through the lanceg system, the gear or the belt. It is allowed to achieve the greatest speed of tension-vaga (which is higher than the speed of the electric motor, with the help of the lighter yoga you can work for the same tension). For example, an aircraft model engine with a pressure of 6 kW can save only three more per kilogram:

For alignment, direct-drive motor-wheels with nominal pressure (Cromotor, Crystalite, Quanshun) should weigh 12(!) kg. Also, the alignment of the motor closer to the central part of the bike gives the correct alignment, allowing you to beat such bikes, including those for stripping and tricks. Can practice in optimal modes navit on steep slopes and deep mud.

However, the intensity of serial central motors for electric bicycles is rated at 500 watts. The most advanced solution currently available is a 1500W Cyclone kit:

The most powerful solutions on the basis of central engines are chosen by enthusiasts independently, there are no serial ready-made propositions. With the creators of such hard stories, a number of technical tasks are to blame.

reduction. For high-speed motors to reduce the revolutions (from a few thousand to 500-700), it is necessary to install a gearbox (there are no ready-made special gearboxes, you can find the wine yourself) or a lancet / belt transmission with high gear ratios (preparing independently the gears of the required diameter).
UPD: Vtіm, the solution is beginning to appear.
Broadcast. For high-power engines, a standard lancet for a bagatose-width high-rise bicycle is not suitable - the wines simply break or wear out too fast. It is necessary to use a wide shoulder strap for one-piece BMX bikes, a shoulder strap for a moped or a minibike or a strap. And tse often lead to the need to prepare non-standard gears, bushings and a flexible coupling.

Refrigeration. Compact high-speed motors (often, as a middrive, stop model aircraft engines, they are insured for operation in the minds of an intensive air blower), when running on electric bikes, they need to be cooled down before cooling: primus air, installation of a heat exchanger, cooling P.
Shvidkost. Even though a bicycle lanyard is used for transmission and a standard bicycle cassette for shifting gears, then when shifting under high pressures, the cassette is no longer suitable. The camp and planetary bushings do not seem to be roaring; The best option is NuVinchi variable bushings, which allow you to smoothly change the transmission speed. Another problem is that in the Moscow cycle, the manual shifting of the speed is not manual, it is necessary to step on the gas handle, but also on the handle, shifting the gears, which reduces the simplicity and ease of shifting by an electric bike. Exit here can be automatic planetary/variator bushings, which showed up in the rest of the hour. Prote in tight (2 kW) bicycles with a central motor in the gear shifting is often used, which simplifies the design and control, since the high-speed synchronous motor with reduction allows you to see a high moment on a be-yak_y shvidkost.

And also wax-rotating engines, gearboxes and gears make noise.

Tim is no less, the bells and whistles of their central motors gain great potential and more and more often they will win in tight electric bikes, ready-made knots and solutions will appear in the world. For the time being, prote, potuzhnі middrayvi zalishayutsya a share of okremih enthusiasts or firms that create individual solutions for themselves.

Bicycle components

Bicycle components for a charged bike can also increase the vanity and require a respectful selection.

Wheels

For motor-wheels, it is necessary to increase the amount of wear (the most common winter may be due to the increased load on the wheel, high speed and “potholes” on the roads), more spokes. Most often with important motor-wheels, install a motorcycle rim.

Hard and wear-resistant galma

For galvanizing an important bicycle on high speeds, you need good hydraulic galma with a larger diameter of the disc and a great resource of pads.
In fact, there are no special galms for tight electric bikes, otherwise the stench is more likely to appear. That’s why it’s the most important galma, that it’s important to cope with adventurousness and to wear it fast, or the most difficult galma for velo-downhill, which is more expensive. It is also possible to twist a galm into a minibike, independently attaching them to bicycle standards (preparing adapters for fixing a galm_vny machine, a galmіvny disk or winding a galmіvny disk).

Stronger forks

Bicycle shock absorbers are also aware of increased wear when working on large wheels with a larger device. For the toughest and most important electric bikes, the only appropriate choice is double-crown forks for downhill; however, it is recognized for the treatment of even great irregularities, the stench is overly soft for driving on asphalt.

* * *

In this way, the class of hard electric bikes requires special attention to components, many of which are too expensive or require additional support. There are no special components for bikes that stand in the middle between a bicycle, a moped and a motorcycle, otherwise the stench only starts to vibrate. Tse create songs of folding, but also open space for creativity.

Transport chi rozvaga?

Tim is not less, we believe that the tight electric bike is the personal transport of the future, which is gaining popularity. Mayuchi all the practical advantages and speed of the scooter, more universal and passing, maneuverability, noiseless, environmentally friendly, cheap to operate. You can take an electric bike at home, for it you don’t need a garage or a parking lot, which is protected, like for a motorcycle or a scooter, which can be safely left on nothing on the street.

However, not only a practical transport, but also a miraculous way of doing it: driving on a swedish silent motorcycle across the road in the “enduro” mode is inexhaustible for adrenaline. So, on a scooter or a motorcycle, which is installed in the cold weather at the garage, on an electric bike

Technical Director of REG.RU Valeriy Studennikov tried to solve the transport problem especially for himself, and then turned his hobby into a startup.

Such a device for a grown-up person can be lifted by force with gatherings, carried through the crossings.

What did you give?

The design of the electric kits and electric bikes Electron Bikes continues to be gradually improved. Nezabar will be ready before the industrial serial release of two models of the bike:

"Standard" (on the basis of a standard bicycle frame): intensity 2.2 kW, battery capacity 1 kW * year, speed up to 63 km / year;

Electric choopers (without pedals) "Electro-classic": intensity 6 kW, speed up to 85 km/year, capacity of two external batteries up to 3 kW * year;

І "Electro-bobber".

The rest is also owned by a unique parallelogram fork made of titanium, issued in a limited edition.

Not much about attachments of an electric bike

A few words about the power of the components of an electric bike, as well as about technical folding, how to stand on the path of the creators of a hard bike.

The main electrical components of an electric bike

Energy for the life of the heart and the brain of an electric bike is stored in battery. The voltage of the batteries of electric bicycles is variable - from 36 to 48 V. Shvidkіsnі devices can be equipped with high-voltage batteries (up to 100 V).
At this time, in the most important place of electric bicycles, lithium batteries are being used (see below for a report on these types), which may increase the energy efficiency. Heavy lead batteries are less likely to be found on found devices.
The battery is stacked with 4 battery centers connected in series/parallel.

For livelihood of low-voltage alarms (headlight, rear light, horn, repeaters), it is necessary to reduce the on-board voltage to the lower one (5, 8 or 12 volts). For which vicory there are highly effective transformations of the post-stroma. DC-DC).

Difficulties of the transitional age

Batteries

Main types of lithium batteries

LiFePO4 (lithium saline phosphate). They can be operated in frost down to -30 degrees, an available dry charge for 45 hours, may have the largest number of charge-discharge cycles (1500-2000), allow more tension, fire safety, not combustible. However, it may be lower for the pet, lower for lithium-ion batteries (that is 2 times higher than the battery with the same capacity), but the roads (although the price of operation is lower through a large number of cycles).
We use it as the main solution in kits for hardtail bikes, due to their dimensions they are not suitable for inserting bike-double frames into the front tricot, where there is not enough free space.
Li-Ion (lithium-ionn). Classical lithium batteries, as vikoristovuyutsya mainly for the life of electronics. The stench is the lightest and most, found, can be the maximum for today's pet's capacity (W * year / kg). However, there may be a narrow temperature range of operation (from 0 to +40 degrees Celsius), a small number of charge-discharge cycles (300-400), which does not allow large jets. Qi batteries are most often used in low-power electric bikes, but for hard-boiled devices, the stench is of little use due to the low C-rating.
LiPo (lithium polymer). High energy capacity, may be the same as in Li-Ion elements. Allow high discharge streams, high C-rating. However, Li-Ion may have fewer charge-discharge cycles (300-700) and a narrow temperature range: when operating below 0, they go out of tune, and in hot weather, due to a short flicker or mechanical faults, they can fall off. Through my temple, I’ll burn the safety on electric bikes only for fearless enthusiasts.
LiNiCo/LiNiCoMnO2 (lithium-nickel-cobalt). Mayuchi advantages of LiPo (high energy density and building seen great streams), relief of their shortcomings: may have a wider temperature range, and, smut, fire safety. Due to their compactness, they are vikorated by us in electrical kits, which are intended for installation on double-wheeled bicycles.

Motori

Motors, which are reserved for electric bikes, can be divided into three classes, the skin has its own few hundred and tense electric bikes.

Gearless motor-wheels (direct-drive)

Reductor (geared) motor-wheels

Central engines (middrive)

Middrive, as it is known by its original name, is the first drive with a high-speed electric motor, which is installed as a rule in the area of the carriage knot, which transmits the susilla through the lanceg system, the gear or the belt. It is allowed to achieve the greatest speed of tension-vaga (which is higher than the speed of the electric motor, with the help of the lighter yoga you can work for the same tension). For example, an aircraft model engine with a pressure of 6 kW can save only three more per kilogram:

For alignment, direct-drive motor-wheels with nominal pressure (Cromotor, Crystalite, Quanshun) should weigh 12(!) kg. Also, the alignment of the motor closer to the central part of the bike gives the correct alignment, allowing you to beat such bikes, including those for stripping and tricks. They can practice in optimal modes on steep slopes and deep delusions.

However, the intensity of serial central motors for electric bicycles is rated at 500 watts. The most advanced solution currently available is a 1500W Cyclone kit:

And also wax-rotating engines, gearboxes and gears make noise.
