The invention discloses a gear shifting control method and system of a bicycle electronic transmission, and relates to the technical field of transmissions. The method comprises the following steps: acquiring an angle value of a magnetic piece synchronously rotating with an output gear of a motor through a Hall sensor; according to the change condition of the angle value, the controller calculates the instantaneous rotating speed of the motor; and according to the instantaneous rotating speed, the controller adjusts the PWM value of the pulse signal, the output torque of the motor is controlled according to the adjusted pulse signal, and the step of reading the angle value of the magnetic part through the Hall sensor is returned until the angle value is equal to the target angle. According to the gear shifting control method of the bicycle electronic transmission, in the gear shifting process, the instantaneous rotating speed of the motor is detected through the Hall sensor and the magnetic piece, the output torque of the motor is updated in real time according to the instantaneous rotating speed of the motor, and therefore the rotating speed of the motor is controlled, the risk that a worm gear and a worm are locked is effectively avoided, and the service life of the bicycle electronic transmission is prolonged. And the gear shifting efficiency and success rate are ensured.
