A moped, along with a bicycle, is a very convenient vehicle. Moreover, it drives faster than its older brother, thanks to the built-in drive. The ability to move quickly without special efforts Isn't this the dream of every cyclist? It is quite realistic to bring it to life - to supply your bike with a gasoline engine or an electric motor.
An assembled moped from a bicycle is a fairly common occurrence in rural areas or regional towns. It is there that they like to put innovative ideas into practice, in particular, to make smart and economical transport out of an ordinary old bike. Have you noticed a similar interest? Then it's time to get down to business!
Option 1: how to quickly assemble a moped with a gasoline engine
Before you start creating a new moped from a bicycle, you need:
- bike;
- gasoline engine and gas tank;
- battery;
- pulleys or gears;
- transmission belt or chain;
- drive cable;
- fastening clamps.
Recommended power - 2 liters. with., and the engine capacity should not exceed 50 cubic meters. see A weaker engine will not allow you to move the bike, you will have to pedal for a while. An engine of sufficient power can be taken from an old moped. Other options are from a chainsaw or lawn mower.
The working unit of the motor, the gas tank and the battery are securely fixed to the frame using mounting clamps. Convenient location:
- on the top tube - the battery;
- the junction of the lower front and seat tubes - the engine;
- next to the engine is a gas tank.
On next step you need to make pulleys - special transmission units through which the engine power will be transmitted to rear wheel. The starting material for pulleys can be small wheels with external barriers, the size of a CD. Mandatory conditions are the strength of the material and reliable fastening.
Do-it-yourself pulley installation on a bicycle:
- The front gear wheel is attached to the motor shaft.
- A second pulley is attached to the hub of the rear wheel of the bicycle.
- A belt is put on the pulleys. The tension force is about the same as that of the chain. The belt must be firmly attached to the wheels, it depends on how accurately the engine will transmit force to the wheel.
If a chain is used instead, then instead of pulleys, gears are placed on the motor and wheel.
So, the transmission is ready, now let's move on to connecting the engine:
- The working body of the motor is connected to the battery.
- Assemble the “ignition” mechanism: an ordinary brake handle is fixed on the steering wheel, then it is connected to the engine body through a cable.
- Set the tension so that the motor starts freely through the handle.
Option 2: we assemble a moped with a gas engine
This is an advanced method, and the result is more like a real moped. To make it, we need:
- gasoline engine;
- moped parts: wheels, shock absorbers, exhaust pipe, brakes;
- proven bike frame;
- tools.
Since here we are going to get a real moped, the frame must have increased strength and weight. Also, mopeds have a slightly different frame design, which may require a little redoing.
Wheels from a moped are put on the frame. You will need to change the design of the fork, as the width of the wheels will be wider than the distance between the dropouts. If possible, install shock absorbers on the fork.
The power unit of the moped should be carefully sorted out and replaced with all defective parts. The propulsion system will require a separate place, for this a welded metal platform at the bottom of the frame would be a good option. The engine and fuel tank are fixed on the site with metal fasteners. It is better to place the battery closer to the steering wheel. An exhaust pipe is connected to the bottom of the engine. The pipe must be firmly fixed to the frame so that it does not dangle during movement.
- Remove the pedals and chainring from the bike frame.
- Install sprockets on the rear wheel from the moped and the engine shaft. A star on a wheel of a larger diameter.
- Put the rear wheel on the frame.
- Use the chain to connect the stars.
Motor connection. The clutch and throttle are connected to the ignition lever via drive cables. The tension is selected so that the engine can immediately start and start spinning the wheel.
Brakes. If only one brake (for example, the front one) can be enough for a bicycle, then it is better to play it safe and install them on both wheels. The rear can be used as the main, and the front as an auxiliary, to adjust the speed.
In general, a homemade bicycle-based moped will look like this:
Converted bike
Since an engine-equipped vehicle moves faster than a conventional bicycle (this is what the alteration is thinking of), for safety reasons it is necessary to put lighting devices on it. Personal protective equipment - helmet, knee pads and special shoes.
How to make an electric bike
If there is no desire to fool around with a gasoline engine, there is another option - to put an electric motor. It can be bought or installed from another device. The first option for creating electric mopeds is preferable, since the necessary power is already provided in the engines.
Installation options - a motor-wheel and an independent engine on a chain or belt drive.
The motor-wheel differs from the usual one by the presence of a drive mechanism in the central part. With the help of wires, it is connected to the control unit. A significant advantage is the ability to make the bike front-wheel drive without making changes to the classic transmission. And if you want, you can even put two motor-wheels. Installing is easy enough, provided the bike itself allows it. However, a bike with such wheels can be attributed to a moped with a big stretch.
Motor wheel kit
An electric moped is a completely different matter, that is, an analogue of the one discussed above. Of course, an exhaust pipe will not be needed here - this is a plus both in terms of reliability and overall weight.
It will be problematic to assemble an engine from scratch at home, so let's look at how to install a finished motor shaft.
Progress:
- Install a new sprocket and belt pulley on the carriage axle.
- A shaft with a drive pulley is attached to the seat tube.
- The pulleys are connected by a belt.
- Through the wires, the shaft is connected to a power source.
- Run the wires from the battery to the steering wheel switch.
speed bike with electric motor
The location of the battery is on the lower front tube of the frame or on the trunk. The scheme of the electric motor:
- When the electric motor is turned on, the rotating roller engages with the rear wheel tire, pushing it.
- Through the pulleys and the front sprocket, torque is transmitted to the transmission.
- Gear shifting causes a change in output torque. In this case, the speed of rotation of the roller is kept constant.
DIY electric bike:
Optionally, a second shaft can be connected to front wheel, connecting it with the driven pulley of the main gear.
The engine allows you to reach the optimum speed faster and hold it longer. A bike-based moped is a budget option become the owner of a faster and more powerful vehicle. The transformation of a bicycle into a moped in most cases does not make irreversible changes to the design, so it is possible to return everything to its place.
If you have a burning desire to make a bicycle with a motor with your own hands, then get ready for the fact that you will have to work a little. In this article, we will tell you how to install a wheel motor on a bicycle and how to make a bicycle with a chainsaw motor your own.
BICYCLE WITH A MOTOR WITH YOUR HANDS: INSTALLING THE MOTOR WHEEL
The simplest and accessible way to make a bicycle with a motor with your own hands is to install a wheel motor. Connecting a wheel motor is not as simple a task as a person who has never encountered it might think. The most difficult part of this process is the connection of electricians.
By purchasing a wheel motor, you also become the owner of the controller, Pas system, throttle handle, charger and brake handle that come with the kit.
Since the motor-wheel is driven by alternating current, the need for a controller is due to the need to convert the direct current from the battery into alternating current.
The PAS system is needed in order to activate the electric motor at the moment the cyclist is pedaling.
On special brake levers there is a microswitch designed to cut off the supply current from the motor at the moment of braking.
To manually install the wheel motor, you will need to perform the following steps:
- First of all, you need to put the bike with the wheels up, and dismantle the old rear wheel. In place of the old wheel, you will need to install a new wheel with an electric motor. The motor-wheel is installed so that the bundle of power wires is on the left, in the direction of the bicycle. If this requirement is not taken into account, then the motor-wheel will simply spin in the other direction.
- After attaching the wheel motor, you will need to attach the batteries to the bike frame and connect the controller. When connecting the controller, a very important point is its additional isolation. You can, for example, protect the device with a plastic bag.
- Next is the connection of the rest of the equipment. Do not forget that all electronics must be connected to the battery through a 20A fuse, it will not allow the system to burn out if a short circuit occurs. Detailed scheme for installation and connection, you will find the wheel motor in the delivery set.
BIKE WITH A MOTOR FROM A CHAINSAW WITH YOUR HANDS
Over time, many cyclists get tired of just pedaling, and their engineering talent and imagination push them to take the step of putting an engine on a bike. As a "donor" for the motor, a chainsaw is perfect. But here's how to assemble a bike with a chainsaw motor with your own hands? Let's try to figure this out.
Take the engine from a chainsaw, whose power is 1.5 hp. Many will doubt that a motor of such power will budge a bike with a 100-kilogram cyclist, but believe me, do not worry: the bike will easily accelerate and pick up speed of 30-35 km / h.
For the sake of justice, it must be said that acceleration cannot be called fast, but this does not interfere with driving. What is good is that with such an engine you will hardly smell gasoline, which makes the option of storing at home possible.
Naturally, during the ride there is a crack like from a conventional chainsaw, which means that you will move with a rather loud sound.
The engine is mounted above the frame under the saddle with a metal clamp. You can buy bike mounts from bike manufacturers and they will come with perforations to adjust the height at which the motor will be mounted, but that's overkill.
The bushing, to which the belt is tensioned from the engine, is fastened with special washers and screws. There are bushings of various diameters for different wheels: from the smallest to simply huge ones, for 28-inch wheels.
Inside these bushings have a rubberized surface. Based on what was said earlier, it is not difficult to guess that the drive belt must be selected, taking into account the diameter of the bushing and the diameter of the wheel. An important point is also that the sleeve must be fixed evenly, excluding any distortions.
Lever "gas". Its control is carried out using a cable that regulates the angle by which the damper in the engine carburetor deviates. This lever is similar to the brake lever from a bicycle, which means that you will accelerate without turning the handle, as in a moped, but by pressing the lever, as in a chainsaw.
Bicycle motor sellers offer an option that is mounted on the handlebars, but it is better to bring the gas cable to the front brake handle and remove the brakes themselves, since, given the low weight of the vehicle, you will definitely do a somersault if you press the front brake at a speed of even 20 km/h.
To sum up the result you should get: a great motorbike at a low price. Very nimble and bringing a lot of pleasure. Although, this option has its drawbacks: because of the noise, every dog in the holiday village considers you a personal enemy, trying to catch up with you and bite you!
A bicycle is a vehicle that allows you to simultaneously get to the desired point, do your own thing. physical form and turn every trip into a walk. It does not need to stand in a traffic jam or crowd in a filled subway car, returning home from work. It is environmentally friendly. But at the same time, he also has a drawback: not everyone can overcome long distances. Still, the physical form may not allow you to drive several kilometers without stopping. But a solution to a problem can always be found. In this case, you can make a motorbike with your own hands.
Peculiarities
Motorbikes can be purchased at the store. But they are quite expensive and appearance yet far from desirable. Yes, and this design weighs about 20 kg. This weight will greatly complicate the road if the engine fails and you have to pedal. Such shortcomings can be avoided if you make a motorbike with your own hands.
This type of transport was widely popular among teenagers during the Soviet Union. But modern capabilities and tools allow you to significantly change an ordinary bicycle and create an original vehicle. Experienced do-it-yourselfers, when asked how to make a motorbike with their own hands, will answer that it is very simple. Almost everyone can cope with such an activity.
Types of engines
Getting started, you need to decide which is better to choose a motor for a bicycle. They are of two types:
- Electric, which with the advent of compact, but capacious batteries are becoming more popular.
- Internal combustion engines, which are the traditional option.
To create homemade motorbikes, gasoline engines can be used from lawn mowers, chainsaws and other tools and assemblies.
Engine selection
Most often, an old chainsaw is taken as the basis for making a motorbike with their own hands. Or rather, its engine. But here, too, there are some limitations. Do not take engines from small and light saws. They have too little power. Suitable for a bicycle motor, the power of which is above 2 liters. With. (or 1.5 kW). And the higher this value, the better. But even with the specified value, the bike will be able to accelerate to 30-35 km / h.
When choosing an engine, you should also pay attention to volume. In accordance with the Vienna Convention, this value should not exceed 50 "cubes". Only in this case, the rights and registration of the vehicle will not be needed. The motorbike will then fall into the category of "motorcycles with outboard motors".
Another advantage of such an engine is the absence of the smell of gasoline. The motor practically “does not smell”, which allows you to store the bike at home. But there is also a drawback. It consists in the characteristic sound of a working chainsaw. The sound of a running engine will accompany you throughout the trip.
Connection of individual parts to the frame
To create a motorbike, you can use any rusty, folding. A motorbike requires only a solid frame from the base. If one is not available, you can make it yourself. To do this, you need several pieces of metal pipe.
The motor is attached to the frame at the junction of the lower and seat tube. This is the most optimal, but not the only option. Sometimes you can see the motor mounted on the trunk. The main thing is that the fastening is reliable. During operation, vibration will be felt, due to which the motor may fall if it is loosely fixed. For fastening, it is recommended to use metal clamps. A kit for a motorbike may include special perforated mounts. But their use is not mandatory.
In addition to the engine, the battery and fuel tank must be fixed to the frame.
Connecting parts
Fixing all the parts individually to the bike frame is only half the job. Next, you need to combine all the elements into one system. Otherwise, a homemade motorbike will lose all its new features.
The first step is to connect the motor so that it transmits rotation to the wheels. For this, a special mechanism must be provided. There are two options for these mechanisms: with pulleys or chains.
Provides for a pulley system. This is an easier option. One pulley is put on the motor shaft. The second is fixed on the rear wheel hub. Between them is put on a tension belt. The disadvantage of this option is the shorter life of the belt (which stretches faster) compared to the chain. It should be noted that V-belts in terms of their characteristics (service life) are not inferior to chains.
In the case of a chain drive, the rotation from the engine to the wheel comes through the chain. On the one hand, it is put on the rear wheel sprocket. On the other - on the gear, put on the motor shaft. chain drive more durable than belt. But it requires regular maintenance.
The battery is connected to the engine ignition and the brake lever. Next, you can install the exhaust pipe. You can do without it, but the exhaust gases will overshadow the trip.
Electric motor installation
The use of a gasoline engine when creating a motorbike with your own hands “kills in the bud” the idea of \u200b\u200ban environmentally friendly vehicle. Therefore, models with electric motors are becoming more and more common. The development of modern technologies allows this to be done.
The principle of installing an electric motor is similar to mounting gasoline engines. This will require, in fact, the motor itself, a battery, parts for control, a controller.
motor wheel
Another option that can be chosen when creating a motorbike with your own hands is to install a motor-wheel. This option is suitable for those who understand electrics. Connecting a motor-wheel requires certain knowledge, without which it will be difficult to assemble an electrical circuit.
The sale kit of the motor-wheel includes controllers, front and rear brake handles, the Paz system, and a charger.
The battery generates direct current. The controller converts direct current into alternating current, which, in turn, will drive the wheel motor. When the wheels start spinning, the electric motor is activated. For this, the system "Pass" notes. The brake levers have a microswitch. It is necessary in order to turn off the power supply from the motor to the wheels during braking.
It is carried out in accordance with the following steps:
- The bike turns upside down. The rear wheel is removed. In its place will be a motor-wheel. It is attached in such a way that the outgoing wires are on the left (when viewed in the direction of the bicycle). This controls the direction of rotation of the wheel. If the sides are reversed, the wheel will "go" in the opposite direction.
- The controller and battery are attached to the frame. The controller must be well insulated.
- Next, the rest of the parts are installed and connected.
Collecting electronic circuit, it is important to remember that the battery is connected via a fuse (20 A is enough). It will protect the system from fire in the event of a short circuit.
Conclusion
As you can see, there are several ways to make a motorbike with your own hands. Each of them has its own advantages and disadvantages. Installing the motor on the bike does not interfere with riding in the usual way (pedaling). To do this, just turn off the motor and clutch of the motorbike. This is very convenient when you want to take a leisurely ride and get in shape. The option of a bike equipped with an engine (regardless of its type) is a good option for people who choose an active lifestyle. It is both a vacation and a way to move around the city (and not only).
Both a bicycle and a moped are very convenient means of transport. The fact is that their maintenance is not expensive. However, today many are interested in how to make a moped out of a bicycle. To do this, you need to choose the right parts.
So, first you need to decide on the frame of the product. It must be strong and unbreakable. Therefore, it is better to give preference to the basis of mountain bike made from aluminium. It can be foldable. However, if you are going to ride over rough terrain, then it is better to choose If you do not know how to make a moped out of a bicycle, since this procedure is not difficult. First, find the scheme by which you will install all the components on the structure. There are countless of them on the Internet.
Now pay attention to the body kit. It's best if it's on high level. In order for such a miracle of technology to go, it should be equipped with an engine. Moreover, the “heart” of the design can work on gasoline or electricity. The second option is simpler and lighter, as it does not require a fuel tank. However, if you do not know how to make a moped out of a bicycle that will run on gasoline, choose an engine from garden equipment. Pay attention to the number of revolutions and the weight of the machine.
The engine is mounted above the front or rear wheel. Next, you need to provide a place for a gas tank or electric accumulator. Naturally, it is mounted on the front of the frame. Before you make a moped out of a bicycle, go to technical stores, because a ready-made kit for installation can be sold there.
Now you should move on to installing the gearbox. The simplest option is the usual not too rough chain that connects the wheel and the engine directly. You can, of course, install a variator that will not reduce As for the clutch, it is better if it is automatic centrifugal. In principle, how to make a moped out of a bicycle is understandable, you just need to choose the right mechanisms. For example, when choosing a motor, pay attention not only to its power, but also to which it will publish.
The operation of such a system is quite simple: a belt or chain is attached to the sprocket, which are put on the engine pulley. When he starts to work, the bike starts to ride. The pedal can be used to start the engine.
From a bicycle can be quite convenient transportation. The fact is that they do not consume a lot of energy, are not difficult to maintain and repair, and also do not require a driver's license. In addition, the cost of such a design can be quite low, which makes such a technique popular.
The electric version of such transport is more profitable, cheaper and safer. All mechanisms are installed on special mounts, which can be screwed to the frame or welded to it. That's all the features of making a homemade moped.
It would seem that absolutely incompatible things will not allow you to get a truly original invention, but in practice this assumption has been refuted more than once. In particular, for those who do not know how to make a moped, having only a bicycle and a chainsaw from improvised means, this article will be very informative.
Moped with petrol engine
If you don’t want to fill up your car every day, and riding a bike is too tiring, then a homemade gasoline moped will be the perfect solution to your problem.
What do we need
Nowadays, there are many ready-made kits that include an engine of the required power and other parts needed to remake a bicycle. Purchasing this kit great option for those who want to become the owner of a bicycle with a motor, but do not have the opportunity to make fasteners with their own hands or choose a suitable engine.
However, there are situations when, despite possible difficulties I want to do all the work myself. In this case, it is worth starting with the choice of a suitable power unit, the role of which can be played by one of the parts of old and unnecessary household utensils. A lawn mower or a chainsaw are the most suitable donors for a “heart” transplant, but do not forget about the power of each such unit. So, a homemade moped from a bicycle should be equipped with a 2 hp engine. and volume not exceeding 50 cm3. A weaker motor will not be able to move the bike, and you will have to pedal for a while.
In addition to the power plant, you will also need other parts: a battery, pulleys and gears, a transmission belt (it can be replaced with a chain), a drive cable and mounting clamps. Of the tools, screwdrivers, pliers, wire cutters and other components of an auto mechanic kit will be useful.
We equip the frame
The bicycle frame becomes the main location for all the details and elements of the future moped. In particular, with the help of mounting clamps, the engine, gas tank and battery are attached to it. Most good option their locations are as follows:the battery is on the top tube, the engine is at the junction of the lower front and seat tube, and the gas tank is right next to the motor.
We make pulleys and install them
The next step towards creating a moped with your own hands is the manufacture of pulleys - special transmission units, through which the motor force will be transmitted to the rear wheel. As necessary materials you can use small wheels (the size of a CD), supplemented by an external barrier. Required condition when creating pulleys, this is the strength of the parts used and the reliability of their fastening.
Installation of these parts on a bicycle is carried out in the following sequence:
1. The front gear wheel is connected to the motor shaft.
2. The second pulley is attached to the hub of the rear wheel of the bicycle.
3. Then a belt is put on the pulleys, setting the tension force, like a chain.
Note!The belt must hold well on the wheels, since the accuracy of the transmission of force from the engine to the wheel depends on this. In the case when a chain drive is used instead of a belt drive, gears take the place of the pulleys.
Motor connection
After the transmission is installed on the bike, you can proceed to connect the power unit. To do this, its working body is connected to the battery and the "ignition" mechanism is assembled. The motor mounted on the bike is connected to the brake lever, which is also an integral part of the do-it-yourself moped assembly. The tension of the connecting cable must be set so that the motor can be started freely through the handle.
Interesting fact!Worldwide, there are about twice as many bicycles as there are cars and motorcycles. In addition, 50 million new unpowered two-wheelers are produced each year, while conventional cars only add 20 million to their ranks.
Assembling a moped with a gasoline engine
Compared with the previous option, this method will allow you to get a more "advanced" vehicle, which almost completely corresponds to a real moped.
What do we need
To accomplish this task, you will need the gasoline engine itself, spare parts from a real moped (wheels, shock absorbers, brakes and exhaust pipe), a strong, welded bicycle frame and working tools (including a welding machine). Considering that in this option you are going to make a real motorcycle out of a bicycle, its frame must have the appropriate weight and strength. You can try to find a part from a small moped, but if it doesn’t work out, then a “skeleton” from a bicycle in the style of “Stork” or “Yew” will do.
Preparing the frame
Suppose you could not find a ready-made frame from a moped, which means you have to strengthen the bicycle one. To do this, you will need a welding machine and an additional pipe, which is welded onto the existing structure, thereby connecting the seat and steering part. However, it must be said that this is not the only possible way increase strength, and iron strips can be used instead of a pipe.
Note! If the selected engine is not fully functional, then it should be carefully sorted out, replacing the failed elements. Although you still do not fully understand how a motorcycle can be made from a bike, the good condition of all the elements used should not raise any doubts.
By the way, the power plant requires a separate place, and the best option there will be a welded metal pad located at the bottom of the bike frame. The motor and gas tank are attached to it with metal fasteners. It is better to place the battery closer to the steering wheel, and connect the exhaust pipe to the bottom of the motor.
We create torque
The next step on the path to creating an electric bike with your own hands is the organization of a power unit torque transmission system. First you need to remove the pedals and the front star from the bicycle frame. Then sprockets are installed on the rear wheel from the moped and the motor shaft (the star is located on the wheel with a large diameter). After that, the rear wheel is put on the frame and the stars are connected using a chain.
We connect the engine
After completing all the above steps, it remains only to connect the motor correctly. To do this, the clutch and throttle must be connected to the ignition lever by means of drive cables. The tension force is selected so that the motor can immediately start and start spinning the wheel. Once you connect power unit, consider that you have already managed to make a bicycle on a motor.
It's no secret that an engine-equipped vehicle will move faster than a conventional bicycle, so for safety reasons, it is also worth installing lighting, and the driver himself must use a helmet, knee pads and special shoes. That's all. Another answer to the question "How to make a motorbike with your own hands?" I'm ready now.
Do you know?Cycling helps maintain great shape. For example, an hour of cycling contributes to the loss of 600 calories.
We create an electric bike
If you do not like the idea of using a gasoline engine on a bicycle, then you can consider an alternative option to improve this vehicle with electrical equipment.
Benefits of electrical equipment
The emergence of modern electric vehicles has allowed mankind to appreciate all the advantages of this type of transport. An environmentally friendly and economical car almost immediately gained worldwide popularity, easily “telling” motorists about all the privileges of using electric motors. Therefore, it is not surprising that many people were interested in the question “how can you make an electric bike out of a bicycle?”. The electric engine is quieter, does not emit harmful exhaust gases into the atmosphere and does not heat up as much as its gasoline counterpart.
In the case of a homemade electric bike, the role of the engine can be played by a car starter, a screwdriver, or any other power plants available on the farm. Along with the electric motor, an important component of the already converted vehicle is the controller (or regulator), whose task is to accelerate the moped bike under optimal operating conditions of the power plant. To start the movement, a very small current is supplied from the controller to the engine, due to which the motor begins to rotate smoothly. In a braking situation, the controller regenerates the driving energy in electricity that feeds the battery. The battery is almost the same fuel tank, but much more environmentally friendly. Often it consists of a matrix and batteries connected to a specific circuit.
The simplest homemade electric bike includes only a motor and a battery. After mounting the motor, it can be energized using a conventional switch. However, you should also be aware of the impracticality of this approach, because, having a powerful power plant, it is somewhat more difficult to start on such a vehicle, and this can lead to an accident. It is better to use a low power unit that can provide a slow start, even if it does not accelerate to serious values.
Assembly step by step guide
There is enough a large number of ways to assemble an electric bike, but the easiest way is to connect the drive to the tire. If you had a Soviet-built bike, then you probably came across a dynamo to connect the headlight. By the same principle, the electric motor is connected to the wheel. Of course, when using this method, the drive efficiency will be very small, but this is quite enough to test the vehicle on electric traction.
The second option, how to make a good electric bike with your own hands, involves installing an additional star on left side wheels and engine mounting with a star on the trunk. If you connect them with a chain, then we get the simplest chain drive. However, as in the previous version, there will be mechanical losses, and the appearance is not particularly attractive.
Therefore, it makes sense to consider the third and most suitable way to convert an ordinary bicycle into an electric bicycle. It involves the use of a special motor-wheel, which allows you to get an electric motor for a bicycle with an excellent aesthetic appearance and high efficiency, which will make it possible to create a unique vehicle with your own hands. The motor-wheel differs from a conventional wheel by the presence of a drive mechanism in the central part. It connects to the control unit via wires and makes it possible to create a front-wheel drive bike, without changing the classic transmission.
If there is a desire and opportunity, you can install two motor-wheels at once. The installation process involves the following steps:
1. A new star and a belt pulley are mounted on the axis of the carriage;
2. Then a shaft with a drive pulley is attached to the seat tube;
3. The pulleys are interconnected with a belt, and through the wires the shaft is connected to a power source;
4. The wires from the battery are pulled to the switch on the steering wheel.
Note! The battery is best placed on the lower front tube of the frame or on the trunk.
Summing up all of the above, it should be noted that it is still possible to assemble an electric bicycle in the DIY style, but for this you need to find all the necessary details, spend a little time and nerves. The very operation of such a vehicle should not be accompanied by any difficulties, of course, except for the surprised looks of passers-by, which, however, is more of a compliment to you.
Interesting to know! When boarding a bicycle, most people approach it from the left side, flipping right leg, which is explained by the presence of a chain and a star on the other side. The habit of placing the chain on the right side came from riding, since the sword, located at the left hip of the rider, made it difficult to land on the right.
