Getting started assembling an electric bike


A feature of these bikes is the lack of a rear foot brake. They provide for manual braking of the rear wheel by means of rubber pads, and two multidirectional levers in the form of an arc. Their compression comes from pulling a steel cable, connected to the handle on the steering wheel. The principle of the driving module is based on the transmission of torque from the engine to the bicycle wheel through the auxiliary wheel with a rubber coating.

Engine preparation


The engine has a regular cylindrical shape, to the body of which two metal mounting corners are welded. It is necessary to fix a wheel on the motor shaft, which will transmit torque when it comes into contact with the tire is large.
In size, it should not exceed the diameter of the engine casing so as not to overload it during operation. It can be a rubberized wheel for trucks, equipment or even of furniture.

Installing the engine on a bicycle


Using plates with holes and a small piece of the board, we fix the engine to the bicycle frame on the bolts. We center it so that the auxiliary wheel has uniform contact with the tire is large.

To protect against dirt and dust in bicycles, a wing is provided, which in our case is metal. We leave it in its place, making a hole with a grinder under the device wheel.

For power batteries, the author chose inexpensive lead-free 12 V connected in series, suggesting, as an option, placing them in an old laptop bag. It can be attached behind the saddle, on the side of our device.

We remove the wires from the batteries, connect them in series with the engine and lead to the steering wheel toggle switch. There are no speed control controllers, I pressed the button - the full voltage of 24 V was applied to the motor from the batteries. The simplest toggle switch can be fixed somewhere in a convenient place on the steering wheel.
To protect the driving mechanism of our electric bike, you can fix the metal plate on both sides of the frame.

    “We leave it in its place, making a hole with a grinder under the device’s wheel” - of what ????? Grinder ????? Have you seen this "hole" made by a grinder? Author, why lie so ???? Such a HOLE in the wing can be made only with extremely crooked hands with a blunt chisel, knocking on it with a brick fragment !!! "Grinder" here does not even smell close .... P.s. But the idea is good, something to finish, bring to mind, and you can apply it practically!

      Until the first rain, all this will work. I would like to see you when you go fishing from a dirt road.
      For trips around the house, in clear and dry weather and on asphalt, it will pull, but the tire will wear out very quickly. Friction for rubber is not good.

    It’s easier to criticize, but to do it yourself is weak?

      As a physical education teacher told us in grade 9, having sex in a condom is like sucking sugar through a glass.
      Here the author is engaged in this. If it’s so rugged, then you need to change a lot in the bike, the carriage, the rear hub and do everything wisely. And this is pure sucking sugar through the glass.
      To remake a bicycle (regular) to electric traction, factory conditions are needed. At home, it’s utopia.

    when you press the brake, it is necessary that the motor moves away from the wheel, well, and pressing the spring seems to me not bad to do
