In one embodiment of the present invention, a steering mechanism for a children's toy vehicle comprises a non-circular wheel piece connectable to a wheel turning mechanism of a toy vehicle. An arcuate front portion extends along the front periphery of the wheel piece. Preferably, the steering mechanism further comprises a curved rear portion along the rear periphery of the wheel piece. In one preferred embodiment of the present invention, the steering mechanism includes a rear portion which is nested between two end portions of the front portion and the front portion and the rear portion form a tulip shape. In a further preferred embodiment of the present invention, the steering mechanism and wheel piece is combined with a front wheel frame which is connected to the wheel piece, a front tricycle wheel mounted to the front wheel frame, and a rear wheel frame which is pivotably coupled the front wheel frame. Two rear tricycle wheels are mounted to the rear wheel frame. The wheel piece of the steering mechanism is connected to the front wheel frame at a point eccentric to the wheel piece, and optionally is connected to the front wheel frame at a point offset forward from the center of the wheel piece.

The steering mechanism of claim 6, wherein said grips are contoured. 8. The steering mechanism of claim 6, wherein said grips are formed with a resilient material. 9. The steering mechanism of claim 6, wherein said wheel piece is primarily made of blow-molded or injection molded plastic. 10. The steering mechanism of claim 9, wherein said wheel piece incorporates one or more portions covered with a resilient cushioning material. 11. The steering mechanism of claim 6, wherein said openings are oval shaped. 12. The steering mechanism of claim 3, in combination with a front wheel frame connected to said wheel piece, a front tricycle wheel mounted to said front wheel frame, a rear wheel frame pivotably coupled to said front wheel frame, and two rear tricycle wheels mounted to said rear wheel frame. 13. The combination of claim 12, wherein said wheel piece is connected to said front wheel frame at a point eccentric to said wheel piece. 14. The combination of claim 13, wherein said wheel piece is connected to said font wheel frame at a point offset forward from the center of said wheel piece. 15. The combination of claim 13, wherein said front wheel frame and said front wheel define a turning axis, wherein said front wheel frame is coupled to said rear wheel frame along a pivot axis, and wherein said turning axis is parallel to and offset forward from said pivot axis. 16. The combination of claim 12, wherein said coupling between said front wheel frame and said rear wheel frame is along a pivot axis, wherein said front wheel frame is connected to said steering wheel piece along a mounting axis, and wherein said mounting axis is parallel to and offset forward from said pivot axis. 17. The combination of claim 16, further comprising a seat mounted to said rear frame portion and a pedal crank coupled to said front wheel to propel said front wheel. 18. The steering mechanism of claim 3, wherein said wheel piece has a downwardly recessed central portion.
