A skateboard having a fifth wheel attached to the board and coupled to a motor mounted on the board for driving the board in response to operation of the motor. The fifth wheel is attached to the board near the longitudinal center of the board and extends through a slot in the board for coupling to the motor. The board is resilient and the diameter of the driven wheel is of such dimension in relation to the height of the board above the ground and of the trucks that support the board, and in relation to the resiliency of the board and the height of its attachment to the board that drive wheel does not contact the ground to drive the board unless the weight of a person on the board is distributed toward the longitudinal center of the board so as to flex the longitudinal center of the board toward the ground.
