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