A cambering vehicle includes a single steerable front wheel and a pair of rear wheels at the rearward ends of trailing arms extending from the front structure. The two trailing arms are articulated to the front structure, and may move arcuately in a plane parallel to the front wheel column of the vehicle. The two trailing arms are linked together by a novel yoke mechanism, and move in opposite directions but in equal arcuate distances relative to one another. The vehicle operates using the principle of conservation of angular momentum, with the vehicle traveling a sinusoidal path and the operator leaning to the inside of the turn. This moves the center of gravity of the vehicle and operator to the inside of the turn, thus accelerating the vehicle and operator along the path of the turn to increase the velocity of the device. The yoke mechanism of the vehicle may be quickly and easily removed, thus allowing the vehicle to be folded for storage. The yoke mechanism also allows the vehicle to be provided with a simple, fixed stop mechanism for limiting the arcuate travel of the two trailing arms. The present vehicle is also equipped with brakes for the two rear wheels, with dual operator controls independently actuating each brake. While the present invention is primarily directed to a wheeled vehicle, the operating principle is applicable to use with skis, skates, and other sliding contact devices as well, with such sliding contact devices being adaptable to the present vehicle.
