A novel structure in a scooter type sport vehicle is presented. The vehicle is of the type which includes a supporting frame structure in combination with at least front and back wheels mounted for rotation with respect to said frame to define a wheeled vehicle. A rockable platform for supporting a standing rider is supported pivotably on said frame. The platform includes an extended forward portion so as to make the platform non-symmetrical with respect to the pivot, and the platform may be rocked back and forth on the frame about the pivot point with increased leverage exerted in the forward direction. Driving means responsive to the forward rocking movement of the platform is included for producing a unidirectional turning moment on the real wheel, whereby a rider may shift his weight to forwardly rock the platform and thereby propel the wheeled vehicle forward.
