ABSTRACT

A two wheeled, rider propelled vehicle having both wheels pivotably mounted upon a medial principal frame. The pivotable rear wheel frame supports pedal mechanism propelling the rear wheel and may be steered by the feet of the user. Mechanical biasing means communicate between the pivotable rear wheel frame and main frame to bias motion and a latching mechanism allows fixed positioning of the two members. A vertically adjustable seat is fixedly carried by the principal frame and the forward portion of the vehicle provides a traditionally manually steerable, pivotably mounted front wheel frame.
