Abstract
Abstract A carrying device for small two-wheeled vehicles such as mini bikes includes a clamp for securing the carrier to a conventional trailer hitch. The clamp includes an upper plate having an upwardly concave socket surface complementary to the curvature of the ball hitch and a lower socket which receives the ball hitch nut. The upper and lower plates are clamped together by a pair of bolts. Support arms extending upwardly from the upper plate include cantilevered portions for supporting a vehicle or the like.
