Abstract: A bicycle wheel includes a central hub and a rim including multiple openings positioned about the circumference of a radially inner surface of the rim. A rivet nut or similar attachment element is positioned in each opening and coupled to the rim. A first end of a nipple or similar coupling element is threaded into or otherwise attached to each rivet nut. A first end of a spoke is threaded into or otherwise attached to a second end of each nipple. A second end of the spoke is coupled to or engaged with the central hub. Each nipple optionally includes left-hand external threads and right-hand internal threads, or right-hand external threads and left-hand internal threads, such that rotation of the nipple simultaneously tightens or loosens the nipple with respect to both the rivet nut and the spoke.

Abstract: Improved handlebars for power vehicles such as two wheeled vehicles and all terrain vehicles, and in particular to handlebars for off road motorcycles, dirt bikes, all terrain vehicles and jet skis. The improved design eliminates the requirement for a crossbar by designing handlebars that have a larger diameter central portion including the area where the handlebars are attached to the vehicle, and a unique tapered configuration wherein the handblebars are manufactured through a process that causes the same amount of metal to be located in the widest diameter portion of the handlebars as in the narrowest diameter portion of the handlebars. The handlebars have a longer unsupported span than conventional handlebars, thereby providing more cushioning strength and greater steering control.
