Abstract: A valve assembly for a bicycle suspension system includes a housing, a rotary valve disposed within the housing, and a rotational electro mechanical actuator disposed within the housing. The housing is configured to house shock absorber fluid. The rotational electro mechanical actuator is disposed in operable communication with the rotary valve. The housing, the rotary valve and the rotational electro mechanical actuator define a plurality of fluid flow passages internal to the housing. The rotary valve and the rotational electro mechanical actuator are each subject to contact with or immersion in the shock absorber fluid in the housing when present.

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: An expansible bicycle cargo rack includes a first member, a pivoting mechanism arranged on the first member, a second member arranged on the pivoting mechanism, wherein the second member is configured to rotate about the pivot mechanism between at least two positions, and an elastic member coupled between first member and the second member.

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.

Abstract: The present invention is directed to an integrated crank assembly. Preferably, the integrated crank assembly includes a bottom bracket spindle having an outside diameter of greater than 29 mm, a wall thickness of less than about 2 mm, and a wall thickness to outside diameter ratio of greater than about 11. In one embodiment, the assembly further includes a bottom bracket shell for receiving the spindle and bearing for rotatably supporting the spindle in the shell, where the bearings are mounted directly to the shell. Additionally, preferably the integrated crank assembly features crank arms with an optimized arch roof design. The crank arm includes two crank arm halves that are bonded together. In one embodiment, the wall thickness in each crank arm half varies continually along the length of the crank arm half. The wall thickness is optimized to carry the loads equally along the crank arm. Also, there may be total wall asymmetry throughout the crank arm.
