Patent ID: 8183726

Claim:
An electrical assist bicycle comprising: a parallel pole direct drive motor mounted to a hub of a bicycle to provide electric motor assist, the parallel pole direct drive motor comprising: an outside rotor having a rotor disc with plural magnets having alternating polarities flush mounted into the rotor disc; an inside stator assembly having a ring of magnetic flux channel pole pieces corresponding to a phase of the motor attached with a housing for a transversely wound stator windings to capture and focus the magnetic flux emanating from the transverse winding and channel the magnetic flux to the ring of magnetic flux channel pole pieces; and a sensor for monitoring a timing, speed and direction and for producing a feedback signal; a rechargeable battery connected with the electric parallel pole direct drive motor; and an electronic controller mounted to the frame of the bicycle connected with the sensors and the rechargeable battery to measure and proportion electrical power to the motor, the parallel pole direct drive motor coupling the feedback signal to a processing unit for determining and adjusting a drive electronics for driving the transverse phase windings and generating an electrical energy to recharge the rechargeable battery.
