For travel on narrow trails, the pre-wheels are removed from the side mounts and connected to an auxiliary mount attached to the rear of the frame. Once on the auxiliary mount, the drive wheels are removed and the pre-wheels serve as the rear support for the apparatus. A steering bar is coupled to the front of the frame for towing applications and for steering purposes.

Abstract: An articulated balancer with an oscillating axle and having locking possibilities provides dynamic stability and static balance to a vehicle having a high center of gravity in rounding curves. This vehicle has three wheels, one in front and two in the rear. It rivals the maneuverability of a motorcycle, yet offers a higher level of safety and convenience than conventional motorcycles. The stability in curves is obtained by enhancing the lateral tilting of the vehicle. For this, each rear wheel must allow an up or down motion; each of these motions is opposite to the other but to the same extent. By means of "ball-and-socket" hinged joints, two connecting rods connect the balancer with the rear swinging forks, converting the balancer's rotation to an up-and-down motion. The balancer's axle allows an oscillation motion controlled by a shock absorber, that provides the rear suspension of the vehicle.
