The most popular electric vehicles are beginning to use today, they are environmentally friendly, noiseless, and the energy for their power is several times cheaper. Many craftsmen make electric bicyclesas an example of one of these homemade I propose to get acquainted with this project. The considered bicycle design is very simple and budget, but this does not mean that it is not reliable. Homemade accelerates to 32-35 km / h, the engine here is used at 250 watts, powered by a voltage of 24V. Consider homemade in more detail!
Materials and tools used by the author:
Material List:
- bike;
- steel plate, screws (for mounting the engine);
- engine 24V / 250 W (gear);
- engine control knob;
- controller for the engine;
- batteries (24V);
- bicycle chain;
- battery charger;
- Scotch tape, plastic screeds and other little things.
for electric bicycles can be from China.
Tool List:

Homemade manufacturing process:
Step one. Pens
First of all, the author replaced the handles on the bicycle, we need to install the handle to control the engine speed, we have it electronic. Then it remains only to conduct wiring on the frame, fix it with tape, plastic ties and everything that is at hand.
Step Two Controller
To control the speed you will need a controller, it usually comes with a kit for converting a regular bike into an electric bike. Controllers are for brushless motors and brushless, it is important not to confuse.
The author installed the controller under the seat, but it would be nice to wrap it with a bag or otherwise protect the controller from water.
Step Three Engine
The engine here is gear, it has a fairly high torque. We fasten the engine to a steel plate, which the author has welded to the rear fork of the bicycle.Securely fasten the engine with screws.
Now it remains to establish the chain, the drive is carried out on the rear wheel, on the axis of which the author installed two stars with a ratchet mechanism. Now, even if the battery runs out, you can always get to your destination in the classic pedal way.
That's all, the homemade product is ready, the author rides a bicycle without any problems and quite frisky. The only drawback is the cheap batteries with a small capacity, but this flaw can be eliminated, a matter of investment and desire.
Good luck and creative inspiration, if you decide to repeat. Do not forget to share your ideas and homemade things with us!
