See full text

A bicycle includes a frame having a seat tube, a rear wheel including a drive plate, and a drive system configured to drive rotation of the rear wheel. The drive system includes at least one shaft operably extending in a direction between the seat tube and the rear wheel and arranged to interact with the drive plate. A pair of drive assemblies are located near or at least in part inside the seat tube and are arranged to operably interact with the drive shaft. The at least one drive shaft converts linear motion of the drive assemblies into rotation of the rear wheel without a chain or chainring.
