An end-weighted vehicle comprising a framework having opposing ends and a wheel mounted to one of the ends for rotation and defining a footprint, and a weight supported by the framework proximate the wheel so as not to interfere with the rotation of the wheel, wherein a)the weight is sufficiently heavy and sufficiently distributed proximate the wheel so that the framework is forced to reside in an inclined position with the other of the ends positioned above a supporting surface when the wheel is positioned against the supporting surface, and b)the footprint is of a size sufficient to support and maintain the framework in the inclined condition.

1. An end-weighted vehicle comprising: a framework having opposing ends and a wheel mounted to one of the ends for rotation and defining a footprint; a weight supported by the framework and substantially contained by the wheel so as not to interfere with the rotation of the wheel, the wheel being mounted for rotation to ends of an axle of the framework and the weight being fixedly attached to the axle between the ends of the axle, wherein a) the weight is sufficiently heavy and sufficiently distributed proximate the wheel so that the framework is forced to reside in an inclined position with the other of the ends positioned above a supporting surface when the wheel is positioned against the supporting surface, and b) the footprint is of a size sufficient to support and maintain the framework in the inclined condition; and adjustment mechanism coupling the axle to the frame and adjustable between a loosened condition wherein the axle is rotatable with respect to the frame, allowing the orientation of the frame with respect to the weight carried by the axle to be altered, thereby adjusting the inclined position, and a secured condition wherein the axle is fixed with respect to the frame. 2. The vehicle of claim 1, wherein the wheel is associated with a drive assembly carried by the framework for driving the wheel for rotation. 3. The vehicle of claim 2, wherein the drive assembly is non-motorized. 4. The vehicle of claim 2, wherein the drive assembly is motorized.
