A cambering vehicle, having an upright main frame supporting a front steerable surface contact means and having a pair of trailing arms pivoted at one end to opposite sides of the main frame and having rear surface contact means mounted at the free ends thereof, is manually propelled by the vehicle operator who stands on foot rest means adjacent the rear wheels and, while camber steering the vehicle in a first curved path centered to one side of the vehicle, shifts his body weight from the outside to the inside foot so that the mass initially turning on a first radius is forced to turn on a smaller radius to increase velocity and conserve angular momentum. This stroking action is repeated as the operator steers the vehicle in a second curved path centered to the opposite side of the vehicle. The sinuous camber steering and body weight shifting strokes are repeated as desired to produce a net forward travel.
