Abstract
An electric motor bicycle system with an electric motor driven gear adapted to drive a wheel gear coupled to a bicycle hub. The motor driven gear is coupled to the wheel gear with a chain. The chain may be tensioned with one or more tensioners, which allow for a tighter system geometry. The motor may be supported with a bracket adapted to mount to industry standard disc brake mounting interfaces. In some aspects, the motor driven gear is coupled to the disc mounting interface of a wheel hub. In some aspects, the electric motor bicycle system may also have a disc brake system integrated therein.
Claims1
An electric bicycle system, said electric bicycle system comprising:
- a bicycle frame, said bicycle frame having a longitudinal axis;
- a rear wheel coupled to said bicycle frame, said rear wheel comprising:
- an axis of rotation;
- a first pedal drive side of said rear wheel coupled to a first side of said bicycle frame;
- and
- a second side or said rear wheel coupled to a second side of said bicycle frame;
- a motor unit coupled to said bicycle frame, said motor unit comprising a low aspect ratio electric motor, said motor having an axis of rotation, wherein said motor unit is coupled to said second side of said bicycle frame such that said axis of rotation of said motor is longitudinally forward of said axis of rotation of said rear wheel and within an outside diameter of said rear wheel;
- an output gear coupled to said motor;
- and
- a drive gear coupled to said second side of said rear wheel, said drive gear mechanically coupled to said output gear of said motor.
