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.
Claims6
An electric bicycle motor system, said electric bicycle motor system comprising:
- an electric motor, wherein said motor is a BLDC outrunner electric motor, and wherein said motor comprises a motor stator, and wherein said motor stator has a stator diameter of greater than 4 times the laminate stack thickness;
- a motor mount for said electric motor, wherein said motor mount is adapted to attach to a rear disc brake caliper mounting interface;
- a motor output gear coupled to said electric motor;
- a drive gear adapted to attach to a disc brake disc mounting interface of a bicycle wheel hub;
- a chain coupling said motor output gear to said drive gear;
- and
- a first chain tensioner applying tension to said chain along a first chain portion on a first side of said motor gear.
An electric bicycle motor system, said electric bicycle motor system comprising:
- an electric motor, wherein said motor is a BLDC outrunner electric motor, and wherein said motor comprises a motor stator, and wherein said motor stator has a stator diameter of greater than 6 times the laminate stack thickness
- a motor mount for said electric motor, wherein said motor mount is adapted to attach to a rear disc brake caliper mounting interface;
- a motor output gear coupled to said electric motor;
- a drive gear adapted to attach to a disc brake disc mounting interface of a bicycle wheel hub;
- a chain coupling said motor output gear to said drive gear;
- and
- a first chain tensioner applying tension to said chain along a first chain portion on a first side of said motor gear.
