The invention relates to the technical field of bicycles, and particularly discloses an electric power assisting device and an electric power assisting bicycle. A PCB (Printed Circuit Board) control board is arranged in the motor shell; a magnet is arranged on the end face, away from the driving motor, of the power output shaft, and a magnetic coding chip perpendicular to the power output shaft of the driving motor is installed on the PCB control board. The plane where the magnetic coding chip is located and the plane where the magnetic pole of the magnet is located are parallel and not coplanar. And the central axis of the power output shaft vertically penetrates through the middle part of the magnet and the middle part of the magnetic coding chip. According to the invention, the PCB control board is integrated in the motor shell, so that the circuit arrangement can be simplified, the failure rate is reduced, and the PCB control board can stably and reliably control the motor.
