Abstract
A molded plastic wheel and brake assembly for a bicycle or other vehicle, which aids in isolating a bicycle frame from shocks encountered by the wheel and in isolating the plastic material of the wheel from extreme heating by the brake assembly. The wheel includes a hollow cylindrical hub and five spoke ribs extending radially from the outside of the hub to the rim. Tabs for holding the brake assembly, are formed on the inside of the hollow hub, with each tab located halfway between a pair of spoke ribs, so that the hub portion connecting a pair of ribs acts as a resilient beam to help absorb shock. The brake assembly includes a metal cylinder with lugs at its ends that mount on the tabs of the wheel, to provide an elongated heat path for the transmission of heat to the wheel and to provide an air space between the lugs for dissipating heat.
