Community Q&A. An electric bicycle can easily be built by taking an existing bicycle and adding five parts: 1) a motor, 2) a linkage from the motor to a wheel or pedals, 3) batteries, 4) a throttle and 5) a motor controller (the brain that regulates how much battery power to send to the motor based on the position of the throttle).
An electric bicycle, also known as an e-bike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. With pedal-assist the electric motor is regulated by pedalling. 2  The pedal-assist augments the efforts of the rider when they are pedalling. 3  These e-bikes â called pedelecs â have a sensor to detect the pedalling speed, the pedalling force, or both.
