ABSTRACT:
A childs wheeled riding toy of the three wheeled type having a front steerable wheel and a pair of rear motor driven wheels in which the child sits astride of the toy with his feet resting on opposed foot rest positions of the toy is disclosed having a pair of direct current motors, gear reduction coupled in driving relation to respective rear toy wheels and a pair of like storage batteries for powering the motors. A control circuit for selectively energizing the motors includes a switching arrangement for connecting the batteries in series and to the motors for high speed toy operation, and in parallel and to the motors for low speed operation. A second switching arrangement for disconnecting the motors from the batteries and for connecting the motors to a resistive load for dynamic braking is also included. Still further, a foot actuable dead man switching arrangement which is normally biased to an open circuit condition to preclude application of battery power to the motors is accessible to the child and operable to a closed circuit condition for enabling the motor drive arrangement.
