Abstract
Abstract A vehicle has a circular ring shaped platform frame supported by three swivelled castors. A paddle wheel-seat assembly is spring mounted on the platform in a position for the paddle wheel to engage the floor surface in the center of the ring shaped platform. The mounting for the paddle wheel assembly restricts movement laterally but permits vertical movement so the wheel under weight of a rider overcomes the spring bias to engage the floor surface. A rider propels the vehicle by paddling the wheel, and steers it by balancing or leaning to one side.
