ABSTRACT:
A two-wheel man-powered vehicle having a frame, a steerable front wheel and a rear wheel, both rotatably mounted on the frame. A hand operable power lever has a lower end pivotally mounted on the frame so as to be capable of swinging back and forth in a vertical plane passing through the frame. The lever is constructed in such manner that an upper portion is capable of rotating about its own longitudinal axis. The power lever is provided with a handle at its upper end. A seat for an operator of the vehicle is mounted on the frame so as to be movable back and forth with regard thereto. A flexible transmission mechanism has one end connected to the power lever and one end connected to one of the wheels through a unidirectional drive. The front wheel is connected to the rotatable portion of the power lever by flexible connecting cables so as to be steerable upon rotation of the power lever about its longitudinal axis. A first resilient spring urges backwardly the power lever, and a second resilient spring urges backwardly the operator's seat.
