This invention relates to an electronic gear shifting device for electric motorcycles, comprising an electronic shifting unit, an electronic clutch unit, and a throttle position sensor. Based on the rider's operation, the device outputs a shift signal, a clutch signal, and a throttle opening signal. A vehicle controller receives these signals and determines a target gear for the electric motorcycle. The vehicle controller then looks up a motor torque command based on the target gear and outputs the command to a motor controller. The motor controller then controls a power motor of the electric motorcycle, enabling the electric motorcycle to simulate the power performance of a conventional geared motorcycle without the need for a physical clutch or gearbox.
