The invention is applicable to the technical field of automatic speed change and provides an automatic speed changing method and device for a hybrid power bicycle. The method comprises the following steps that a, a sensor set acquires a current riding state signal in real time and transmits the signal to a microprogrammed control unit (MCU); b, the MCU outputs a control signal to a motor controller according to the current riding state signal; and c, the motor controller controls a motor to output the corresponding assisting speed and assisting gear according to the control signal. According to the automatic speed changing method and device for the hybrid power bicycle, a traditional mechanical gear set type speed change device is abandoned, the MCU performs judging and analysis according to the current riding state signal transmitted by the sensor, and the motor is directly controlled to output the corresponding assisting speed, and accordingly automatic speed change and automatic gear adjusting of the hybrid power bicycle are achieved, and unnecessary judgment and operations of a rider are reduced.
