A power-driving motor (10) for power-driving bike is provided, of which the length is obviously larger than its width. A rotor (14) of the power-driving motor (10) is provided at the outside of the stator (12) so as to make the distance from the rotor (14) to the motor spindle (13) increase; namely, a torque increases and then an arm increases, thereby, making the motor spindle (13) supply a higher output torque to the connected driving unit when the rotor (14) rotates. The motor (10), based on the length of a conventional power-driving motor (10), may supply a higher output torque to solve the defect of a conventional motor implemented with an inner rotor (14) of which the output torque is insufficient.
