After the electrical motorbike starts, the throttle unit receives external operation from a rider for generating a series of original throttle signal. An acceleration compensating module calculates a throttle variation rate based on the original throttle signal and variation of a throttle operation magnitude, and calculates a throttle compensating value based on the throttle variation rate when the throttle variation rate is larger than or equal to a correction threshold. A throttle compensating module receives and sums the original throttle signal and the throttle compensating value up for generating a new throttle signal. A torque controller generates a corresponding torque command based on the new throttle signal, and outputs the torque command to the electro-mechanic assembly for operation.
