  • Patent number: 7213823
    Abstract: This novel all-terrain, two-wheeled, riding-board provides a safe operating sport-ride to the user. Two large diameter wheels, one fore and one aft, are provided to improve the safety of this novel riding-board. Each wheel has a resilient elastomeric pneumatic tire mounted on each rim. A dual set of smaller stabilizer wheels are mounted outwardly at the rear of the deck to limit the travel and prevent tipping over. The outboard repositionable stabilizer wheels also serve to function as maneuvering devices, where the rider, by shifting his body weight over one of the stabilizing wheels, can decisively change the direction of his descent, either to the left or to the right. A dual foot operated braking system is provided where the brake on each wheel is individually operated. Alternatively, the riding board is equipped with a dual braking system—a cable driven hand-brake and an automatically operated hill-brake.
