Abstract: A bicycle frame hinge is provided having a lower and upper portion. The lower and upper portions being movable with respect to each other in both translation and rotation when in a storage condition, and are locked with respect to each other to prevent both translation and rotation when in a riding condition. The lower and upper portions are configured to form an internal cable passage way when the bicycle frame is in the riding condition, and when the bicycle frame is in the storage condition. The lower portion comprises two interlocking features, and the upper portion comprises two interlocking features configured to engage with the interlocking features of the lower portion when the bicycle frame is in the riding condition. A clamping mechanism is disposed between the two interlocking features of the lower and upper portions, the clamping mechanism configured to clamp the upper and lower portions.

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 housing integrally arranged with each other to form a rigid drive link case having an opening disposed between the upper and lower tubes, the drive 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 housing. The front frame portion extends forward from the front housing.
