<p>There is disclosed a hollow-form bicycle wheel (10) formed by injection molding of plastic. The wheel has an integral, central sleeve (12) to receive a wheel hub assembly, at least three, hollow-form, integral spokes (16) that are symmetrically located at equal angular spacings about the hub, and an integrally formed peripheral annulus which is jointed to an independently formed annular rim (20) having a peripheral channel (22) to receive a tire. Preferably the rim is assembled to the mandrel of the wheel and the subassembly of rim and mandrel is placed in the mold cavity (74) used for injection molding of the wheel, thereby bonding the rim to the wheel during its formation.</p> |
