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.

The initial stage of electric bicycles is also known as the early experimental production stage of electric bicycles, from 1995 to 1999. At this stage, we mainly explore and study the key technologies of the four major parts of the electric bicycle: motor, battery, charger and controller. In terms of R&D and production, it is mainly based on the spontaneous collection of information, tracking of technology, organization of market observation, and small batch of market trial launch of the manufacturing enterprises, which also makes the electric bicycle enter the vision of consumers and gradually recognized and accepted by them. From the technical point of view, the early electric bicycles can only drive about 30 kilometers at a time when the new battery is charged. The battery life is short, the climbing ability is poor, and it is easy to wear. Moreover, the motors are also brushless toothless motors. However, the accumulation of this period has laid the foundation for the scale of industrialization in terms of talent, technology and product research and development.
