Abstract
A three-wheeled occupant propelled vehicle is described. A seat is centrally suspended on a longitudinal axis, so that by leaning from side to side, the occupant may impart a steering motion by way of linkages between the seat and the steered front wheels. Said longitudinal axis is disposed vertically above the center of mass of the body of the occupant, so that, by the force of gravity, the occupant tends to stay in a vertical position unless a leaning motion is imparted, and straight line directional control is thus maintained. Motive power is provided by hand-actuated reciprocating levers coupled by a linking means to a driven rear wheel. Power is applied in both the fore and aft strokes of said levers. One embodiment of the present invention includes a variable ratio drive.
