The basic principle of electric vehicle power-assist: it is an organic combination of machinery, electronics, software and magnetism. The system uses double magnetic circuits (active magnetic circuit and passive magnetic circuit) to count the Hall elastic angle difference, detect the dynamic torque generated when people step on their feet, convert the dynamic torque signal into a digital signal, and then convert it into an analog signal and output it to the controller. The system completes the setting storage function and the system error zeroing through the storable single chip microcomputer, ensuring the matching with the whole vehicle and the consistency of the products. It has a good match with electric bicycles in China at present.

Main functions and advantages:
1, save electricity and extend the cruising range: while relaxing and exercising, the cruising range of the whole vehicle is nearly doubled. Because the current used is about half that of a pure electric vehicle, the damage to the battery caused by heavy current discharge is avoided.
2. Set the system afterburner function: it can be changed according to the user's riding mode and the matching between the controller and the motor: the compensation amount of torque parameters and kinetic energy parameters; (Set the panel as shown)
3. Repeated setting: According to the afterburner applied by different users, users can set it when riding, so as to realize humanized operation and meet the needs of different customers.
4. Universal motor controller: brush/brushless, high/low speed, 24V/36V controller-universal motor system.
5. General installation: bicycle sprocket crank with D-shaped shaft.
6. Design concept of modular combination: functional combination can be carried out according to user requirements. (such as instrument components, intelligent dual control, speed control handle, etc.). ).
