  • Patent number: 5765871
    Abstract: A tricycle has a fourth and rear supporting wheel at a distance from and a position above the usual rear tricycle wheels so that the tricycle may be tipped to raise to simulate a wheelie. The distance between the usual rear tricycle wheels and the front wheel is adjustable, so that the maximum wheelie angle may be selected according to the child's age and proficiency. The seat may be moved to make it easier or more difficult to tip the tricycle when the child shifts his body and, therefore, the center of gravity.
