E-bike
E-bike refers to the two-wheeled bicycle fitted with pedals that can propel it. With the on-board battery as auxiliary energy, it is able to achieve electrically assisted and electrically driven functions and meets the relevant safety and technical requirements.
Based on MindMotion’s MM32SPIN0280 microcontroller, the E-bike takes MM32SPIN0280 as its main control.
