A wheel assembly includes a central hub, an outer rim including a spoke bed wall, and a spoke unit including first and second spokes. Each of the first and second spokes extends between the outer rim and the central hub, and has a first end connected to the spoke bed wall, a second end opposite to the first end and connected to the central hub and a span portion connected between the first and second ends. The first ends of the first and second spokes are respectively formed with first and second spoke bed connection portions where the first and second spokes are respectively connected to the spoke bed wall. With respect to the central hub, the second spoke bed connection portion is radially outboard relative to and circumferentially spaced from the first spoke bed connection portion.

A height adjusting device for a bicycle includes a mounting tube, a seat post, and a ratchet member. The mounting tube is configured to be inserted into a seat tube of the bicycle, and defines therein an inner tube space. The seat post is telescopically received in the inner tubular space through an upper open end of the mounting tube, and has a rack region with a plurality of rack teeth. The ratchet member has a ratchet end which is rotatable about a ratchet axis among a forward position, a normal position, and a rearward position, and which is coupled to a selected one of rack teeth so as to permit said selected one of the rack teeth to be kept engaged relative to the ratchet end.

Height adjusting device

A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.
