Spoked wheel assemblies (22, 55) having included angles (50, 70) about a center line (20) passing through tire rims (25, 78) and a midway point on a distance between forks, yielding uniform tension in their sets of spokes (30, 31/76, 77) forming the included angles (50, 70) that are equally divided about their corresponding line (20). A front wheel hub assembly (37) includes a housing 27, a web 28 mounted thereon and passing through the center line (20), a circumferential member (29) mounted to web (28), and a pair of flanges (23) spacedly mounted on member (29). Openings (34) are provided in assembly (37) to lessen weight. A drive hub assembly includes a housing (71), an included angle (70) equally divided about its line (20), a web (72) mounted on housing (71), a circumferential support member (73) mounted on web (72), spaced flanges (74) with their apertures (24) for spokes (76, 77), and a circumferential ring (97) formed on the perimeter (98) of member (73) to maintain a vehicle's chain (100) on the cogs of an adjacently disposed sprocket (99a). Angular inclinations (35) for circumferential member (73) draw the flanges (74) yet closer to the rim (78) of the wheel. Uniform tension and strength in both front and rear or drive wheel assemblies are achieved.
