Abstract
A bicycle frame includes a front section and a rear section. The front section includes a front frame portion having a front coupling configured to receive a front wheel support member and to allow rotation between the front coupling and the front wheel support member, the front frame portion defining a central vertical plane of the frame. The rear section includes a drive link case having an upper tube, a lower tube, a rear hub housing, and a front sprocket housing all integrally arranged with each other to form a rigid drive link case having an opening disposed between the upper and lower tubes, the drive link case being connected to the front frame portion via the front sprocket housing. The drive link case is disposed eccentric to the central vertical plane and is cantilevered rearward from the front sprocket housing. The front frame portion extends forward from the front sprocket housing.
