Disclosed herein is a symmetric bicycle. Accordingly, the symmetric bicycle may include a bicycle frame, a bicycle handle, a plurality of bicycle wheels, and a crank assembly. Further, the bicycle frame may include a seat member, a down member, a top member, and a head member. Further, the bicycle handle may be coupled to the bicycle frame. Further, the plurality of bicycle wheels may be coupled to the bicycle frame. Further, the plurality of bicycle wheels may include at least one front bicycle wheel and at least one rear bicycle wheel. Further, the crank assembly may be coupled with at least one of the at least one front bicycle wheel and the at least one rear bicycle wheel for propelling the symmetric bicycle. Further, the crank assembly may include a crank wheel symmetrically disposed along a vertical plane passing through the seat member.

A bottom bracket for a frame of a bicycle and the frame thereof are disclosed. The frame includes a head tube, a connection member, and two chain stays; one end of the connection member is connected to the head tube; the bottom bracket is adapted to be connected to another end of the connection member and the two chain stays; in a forward direction of the bicycle, the head tube is located at a front side of the bottom bracket, while the two chain stays are located in a rear side of the bottom bracket; the bottom bracket is characterized in that: the bottom bracket comprises at least one joint hole, adapted to receive a bottleneck of at least one compressed air bottle to secure the compressed air bottle to the frame; the secured at least one compressed air bottle is located at the rear side of the bottom bracket.

The present invention provides a bicycle tool storage device mountable in a bicycle headset assembly and/or a bicycle pump. A top cap for loading a headset assembly and mounting the device is also provided. The top cap includes an annular body and a device receiving aperture extending through the body. The top cap includes a flange extending radially outwardly from a first end of the body and a ridge defined in an inner surface of the body adjacent to the flange. The ridge is concentrically aligned with the aperture for retaining the device. Further still, a bicycle pump for mounting the device is provided. The pump includes a pump body, a handle, a pump head, and a flange. The pump body houses a plunger and a piston. The plunger and handle define a cavity for receiving the device. The handle further defines a flange for retaining the device.

A two-wheel vehicle suspension linkage, including a shock and a shock extension assembly, is provided. The shock may include first and second mounting axes operably connected to two linkage bodies. The shock may be positioned to provide linear resistance between the two linkage bodies having relative motion with respect to one another. The shock extension assembly may include a first extension body and a second extension body. Each of the first extension body and the second extension body may include a first mounting axis and a second mounting axis positioned with respect to one another in a non-parallel mounting orientation. The extension bodies may be pivotally connected to the suspension linkage so that the first mounting axis of the first extension body is collinear with the first mounting axis of the second extension body. The second mounting axis of the first extension body may be collinear to both the second mounting axis of the second extension body and to one of the shock mounting axes defining a non-effective shock damper axis.
