ABSTRACT:
A wheel capable of being used as the front or rear wheel of a chain-driven velocipede or as the front wheel of a pedal-driven tricycle has a wheel rim whose hub is formed with an axial passage and an array of receptacles extending inward from the opposite ends of the hub. A pair of identical metal plates are positioned at opposite ends of the hub, each plate having a set of tabs aligned with the receptacles at the associated end of the hub and an axial opening which is in register with the passage through the hub. The two plates are clamped together with the wheel hub between them so that they rotate in unison with the wheel hub. When mounted on an axle, the wheel can function as a non-driven velocipede wheel. Also, pedal crank sections can be inserted through the axial plate openings into the opposite ends of the hub passage and secured to the plates so that the wheel can be used as the front wheel of a tricycle. Still further, a sprocket can be mounted to one of the plates so that the wheel can function as the chain-driven rear wheel of a velocipede.
