  • Ride-on device for transportation and stunt riding
    Patent number: 4941670
    Abstract: A lightweight, easily stored, portable, strong, ride-on-device (1) for transportation and stunt riding. The device is usable on a supporting surface and includes a V-shaped frame (2) on which is mounted an upper and lower body stabilization and support. At least two wheels (6a, 6b, 7a, 7b) are rotatably attached to each of two wheel mountings such that in use, the device may be propelled by potential and/or kinetic energy. The direction of travel of the device is governed by the non-perpendicular positioning of the frame relative to the supporting surface. The device further includes a braking device (8).
