An electric motor bicycle system with an electric motor driven gear adapted to drive a wheel gear (102) coupled to a bicycle hub. The motor driven gear is coupled to the wheel gear with a chain (103). The chain (103) may be tensioned with one or more tensioners (114, 117), which allow for a tighter system geometry. The motor (101) may be supported with a bracket (110) 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.
