Abstract: A wheeled vehicle for children has an open-centered frame that is dimensionally adjustable longitudinally on which a front drive axle and a rear wheel yoke are mounted. An operator's seat having cushion and back portions is secured within the interior and towards the rear of the open-centered frame and the cushion portion is disposed at an elevation substantially equal to the axle height of the vehicle wheel base. The front drive axle has a front drive wheel rotatably mounted on each end, and a pedal portion between the two front drive wheels which propels the vehicle when actuated by the vehicle operator. A steering lever is pivotally mounted on the exterior of each side of the open-centered frame adjacent the operator's seat and is connected to the rear wheel yoke by a steering rod. A rear steering wheel is mounted by the rear wheel yoke and tilting of the steering levers pivots the rear wheel yoke, and, hence, the rear steering wheel about an upright axis imparting a steering motion to the vehicle.
