Abstract: A lightweight wheel assembly intended primarily for use on wheelchairs including an injection-moldable fiber-reinforced plastic push rim, injection-moldable fiber-reinforced plastic wedge-bottom spokes, and a lockable static in-hub brake. Important advantages of the invention include very light weight compared to prior art wheel assemblies while achieving the high component strength desired, shock absorption qualities beneficial to wheelchair users not provided by other wheel assemblies, a convenient and easy-to-operate positive-engaging static brake, and components which may be made from the inexpensive injection molding process.
