The motor is a component that converts the battery electric energy into mechanical energy and drives the electric wheel to rotate. There are many kinds of motors used in electric vehicles in terms of mechanical structure, speed range and power-on form. Common ones include: brushless toothless hub motor, brushless toothless hub motor, brushless toothless hub motor, brushless toothless hub motor, high disk motor, side-hung motor, etc.

The most important accessory of an electric bicycle is the motor. The motor of an electric bicycle basically determines the performance and grade of the vehicle. Most of the motors used in electric bicycles are high-efficiency rare earth permanent magnet motors, which are mainly divided into three types: high-speed brush tooth+wheel reduction motor, low-speed brush motor and low-speed brushless motor.
