Abstract
An electric power-assist drive assembly for propelling a vehicle having a frame and at least one spoked wheel includes a rotatable driving ring supporting a plurality of magnets and mountable to the wheel; a stationary stator supporting a plurality of electromagnets and mountable to the frame proximate to the wheel for overlapping the electromagnets and the magnets; and a control assembly mountable to the frame, stator, or any part of the vehicle for delivering electric energy to the stator to rotate the driving ring; wherein rotation of the driving ring propels rotation of the wheel. A vehicle including the electric power-assist drive assembly and a method of propelling a vehicle using the electric power-assist assembly are included.

An electric power-assist drive assembly for propelling a vehicle comprising a frame and at least one spoked wheel, the electric power-assist drive assembly comprising:
- a rotatable driving ring supporting a plurality of magnets and mountable to the wheel;
- a stationary stator supporting a plurality of electromagnets and mountable to the frame proximate to the wheel for overlapping the electromagnets and the magnets, wherein the stator comprises a substantially curved plate supporting the electromagnets disposed either within or on a top surface of the plate, mounting means comprising a tubular coupling structure formed of a pair of semi-tubular clamp members adapted to fit around a tubular portion of the frame for removably attaching the stator to a portion of the frame of the vehicle proximate to the wheel, and a neck extending between the plate and the mounting means;
- and
- a control assembly mountable to the frame, stator, or any part of the vehicle for delivering electric energy to the stator to rotate the driving ring;
- wherein rotation of the driving ring propels rotation of the wheel.
A method of propelling a vehicle comprising a frame and at least one spoked wheel comprising the steps of:
- providing an electric power-assist drive assembly comprising:
- a rotatable driving ring supporting a plurality of magnets;
- a stationary stator comprising a substantially curved plate supporting a plurality of electromagnets disposed either within or on a top surface of the plate, mounting means comprising a tubular coupling structure formed of a pair of semi-tubular clamp members adapted to fit around a tubular portion of the frame for removably attaching the stator to a portion of the frame of the vehicle proximate to the wheel, and a neck extending between the plate and the mounting means;
- and
- a control assembly;
- mounting the driving ring supporting the plurality of magnets to the wheel;
- mounting the stationary stator supporting the plurality of electromagnets to the frame proximate to the wheel to overlap the electromagnets and the magnets;
- mounting the control assembly to the frame, stator, or any part of the vehicle;
- and
- operating the control assembly to deliver electric energy to the stator to rotate the driving ring, wherein rotation of the driving ring propels rotation of the wheel.
