A vehicle with a vehicle frame including a pair of substantially horizontal rear members extending longitudinally of the vehicle at its rear. The forward part of the vehicle frame is made up of a pair of elongated forward members joined to said rear members and projecting forwardly and inclining upwardly therefrom. The forward members have front portions which converge on each other progressing forwardly and upwardly in the vehicle thus to form a tongue. Rear wheels support the rear members of the frame, and a single dirigible wheel disposed under such tongue supports the forward part of the frame. The engine for powering the vehicle is mounted on said frame with such lodged between the forward members adjacent where they join with the rear members, and located rearwardly of the tongue. Journaling the dirigible wheel on the tongue, is an upright spindle fixed to the tongue and with the upper and lower ends projecting above and below the tongue. Stabilizing collars snugly embrace the upper and lower ends of the spindle and are also joined to the tongue, these being left unjoined to the spindle. Above and below these stabilizing collars are upper and lower bearings which are mounted on a wheel mounting bracket which supports the dirigible wheel.
