A three wheeled vehicle with a pair of steerable front wheels mounted to turn on a kingpin which is inclined forwardly and upwardly. The front wheel axis is offset ahead of the kingpin. The frame tilts in the direction of turning and the vehicle may be steered either by turning the front wheels or by leaning to tilt the frame. The vehicle is driven by a single rear wheel. In one form, the vehicle has a load carrier on the frame which tilts in a turn. In another form, the load carrier is connected with the kingpin and front wheels, remaining level in a turn. The frame has an intermediate joint so that one rear portion may be assembled with different types of front portions.
