Abstract: A cable routing system of a bicycle, including a stem having a receiving space and an engaging hole communicating with the receiving space, a frame, a fork, an expander, and at least one cable. A head tube of the frame has a top portion having an upper mounting hole and a bottom portion having a lower mounting hole. The fork sequentially passes through the lower mounting hole, the upper mounting hole, and the engaging hole to be connected to the stem. The expander is disposed in a steering tube of the fork and has at least one cable passage communicating with the receiving space and the engaging hole. The cable extends into the steering tube from outside by passing through the receiving space and the cable passage. An end of the cable is connected to a bicycle controller, and another end thereof is connected to a bicycle component.

Abstract: A cable routing system of a bicycle, including a frame, a stem, and a fork. The frame includes a head tube and a down tube. The head tube has a top portion having an upper mounting hole and a bottom portion having a lower mounting hole. The down tube is connected to a lower section of the head tube and communicates with the head tube. The fork includes a steering tube sequentially passing through the lower mounting hole and the upper mounting hole to be disposed in the stem, so that the stem is engaged with the steering tube and is located on the top portion. At least one guiding tube is disposed on an inner wall of the head tube. An end of the at least one guiding tube extends toward the upper mounting hole, and another end of the at least one guiding tube extends toward the down tube.

Abstract: A bicycle handlebar assembly includes a stem, two handles and a plurality of fastening members. The stem includes a left extension portion and a right extension portion, with both of the left extension portion and the right extension portion having at least one mounting hole. Each of the handles has a grip portion at one end and a connecting portion at the other end, wherein the connecting portion includes at least two connecting structures. The connecting portions of the handles are detachably mounted onto the left extension portion and the right extension portion, and the fastening members extend through the mounting holes of the stem and the connecting portion so as to secure the stem and the handles together in a non-rotatable manner.

Abstract: An auxiliary control device includes an auxiliary handlebar having a handle member and a cushion member engaged with the handle member, an engaging base adapted to engage the auxiliary handlebar and a main handlebar of a bicycle, and a positioning member. The engaging base has a first base and a second base. The first base is engaged with the main handlebar, and has a first perforation, which has a first inner toothed portion parallel to an axial direction thereof formed on an inner wall thereof. The second base is engaged with the main handlebar, and has a second perforation, which has a second inner toothed portion parallel to an axial direction thereof formed on an inner wall thereof. The positioning member passes through the first and the second perforations. The positioning member has a positioning toothed portion provided on an outer wall thereof, corresponding to and meshing with the first and the second inner toothed portions.

Abstract: A bicycle stern with a shock absorber which is mounted between a handlebar and a steering tube includes a stem body, a clamping member and an elastomer. The stem body has a clamping portion formed at one end thereof, and two fork portions formed at another end of the stein body. The clamping member is connected with the clamping portion for clamping the handlebar, and the elastomer is disposed between the two fork portions. Under this arrangement, when a shock is generated from the rough road, the elastomer is compressed by the two fork portions, so that the elastomer is deformed appropriately and absorbs the shock from the road. Therefore, a rider could hold the handlebar comfortably.
