In sand or mud terrain, steering can also be affected by use of the directional brakes or by only one pilot pedaling.

Races where Rex has competed:

Corvallis daVinci Days: Leo

Other interesting features:

Rex is perhaps the only Kinetic Sculpture with a luggage rack.
Rex introduced the concept of moving the pontoons in the plane of the wheel rotation. This provides the advantage of moving the wheels forward when transitioning from water to land, thus giving more traction to the wheels at a critical moment.
On the road, Rex can be fully driven by one pilot, from either pilot seat.
