A bicycle having a drive-shaft 84 connecting a crank to an internal hub gearbox on a rear wheel 78, the bicycle having a suspension system and a cantilevered rear stay that connects the rear wheel 78 to the frame 102 and maintains the hub in a relative radial distance from the crank to maintain contact of the drive-shaft 84 with the crank and gearbox. The suspension system has a linearly moveable damping device 112 disposed within the frame 102. A swing arm 104 pivotally extends from the rear stay to the damping device 112. The pivotal connection of the rear stay to the frame 102, the linear connection of the damping device 112 to the frame, and the pivotal connection of the swing-arm 104 to both the rear stay and damping device 112 provide a four-bar mechanism to provide suspension for the rear wheel on the bicycle. |
