Abstract
An electric motor assisted bicycle is provided having a fork, a frame, a front wheel, a rear wheel, and pedals drivingly coupled to at least one of the front and rear wheels to enable human powered motion of the bicycle. The bicycle further includes a plurality of bearings uniformly spaced around a perimeter of a rim of one of the front and rear wheels and an electric motor drive system coupled to the bicycle to selectively provide electric motor assisted motion thereof. The electric motor drive system includes an electric motor coupled to the bicycle and a drive cog drivingly coupled to the electric motor, the drive cog positioned to sequentially engage the plurality bearings when driven by the electric motor to power the bicycle in a motor assisted manner. Other bicycle systems and components and related methods are also provided.
