The rear axle has a centrally located string receiving pin mounted to the axle so that when the user forces back the lever arm and attaches the string loop to the axle pin and turns the rear wheel set counter clockwise thereby winding the string about the rear axle and then releases the vehicle, the vehicle is propelled forward when the the torsion spring forces the lever arm to return to a rest position thereby causing the string to unwind thereby causing the rear wheels to rotate in a clockwise fashion.
