Description

The present invention relates to the technical field of electric motorcycles, and more particularly to a combination of power assembly of electric motorcycles.

A conventional electric two-wheeled vehicle mainly uses a motor as a power source and transmits the power to wheels by a transmission device to drive the vehicle. In order to increase the torque of the motor or reduce the rotational speed, the motor is usually coupled to the transmission of the reduction gear set. In order to carry out the operating load, operating rotational speed and maintenance of the motor with the highest operating efficiency, it is necessary to properly combine the motor and the reduction gear set to obtain favorable operating characteristics. Further, it is necessary to combine an appropriate controller (device) with the motor. The controller (device) detects the output rotation speed of the motor and immediately transmits a control signal to control the rotation speed of the motor.
