<P> A hubless wheel (also known as a rim - rider or centerless wheel) is a type of wheel with no center hub . More specifically, the hub is actually almost as big as the wheel itself . The axle is hollow, following the wheel at very close tolerances . </P> <P> A spoke is one of some number of rods radiating from the center of a wheel (the hub where the axle connects), connecting the hub with the round traction surface . The term originally referred to portions of a log which had been split lengthwise into four or six sections . The radial members of a wagon wheel were made by carving a spoke (from a log) into their finished shape . A spokeshave is a tool originally developed for this purpose . Eventually, the term spoke was more commonly applied to the finished product of the wheelwright's work, than to the materials used . </P> <P> The rims of wire wheels (or "wire spoked wheels") are connected to their hubs by wire spokes . Although these wires are generally stiffer than a typical wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads . </P> <P> Wire wheels are used on most bicycles and still used on many motorcycles . They were invented by aeronautical engineer George Cayley and first used in bicycles by James Starley . A process of assembling wire wheels is described as wheelbuilding . </P>
