Claims11
A brushless motor for a bicycle comprising:
- a plurality of ferromagnetic steel elements, annularly disposed on the wheel;
- and
- a plurality of electromagnets connected to the body, each electromagnet provides an opening through which the wheel travels, wherein when the wheel rotates, at least one steel element is magnetically charged, and the electromagnets attract at least one steel element to pass through the gap, maintaining wheel rotation.
A motor-driven bicycle, comprising:
- a main body;
- a main body with at least one wheel thereon;
- a plurality of ferromagnetic steel elements, annularly disposed on the wheel;
- and
- a plurality of electromagnets connected to the body, each of the electromagnets provides an opening through which the wheel travels, wherein when the wheel rotates, the steel elements pass through the opening.
