1. A personal vehicle comprising:
- a first wheel and a second wheel, independently rotatable, positioned opposite from each other, and separated by a distance;
a first motor for driving said first wheel and a second motor for driving said second wheel;
a first frame attached to said first wheel and a second frame attached to said second wheel;
a linking structure coupled to both said first frame and said second frame;
at least one electronic control means for controlling said first and second motors; and
at least one leg contact surface on each of said first and second frames for contacting said person'"'"'s legs, said leg contact surfaces being fabricated of a yielding material;
wherein each of said first and second wheels are capable of tilting side-to-side in unison about a respective wheel tilting axis, relative to the riding surface; and
wherein said at least one electronic control means enacts fore-and-aft balancing of said vehicle.

Abstract
A vehicle with two independently rotatable wheels arranged opposite from each other and bridged by a linking structure, having a driving motor for each wheel, and having electronic fore-and-aft self-balancing capabilities. The two wheels are capable of tilting side-to-side in unison to execute turns. The vehicle can carry a rider, who may stand on foot supports either between or outside of the wheels and operate the vehicle by leaning forward, backward, or sideways to direct travel in the direction of leaning. Further means are provided for producing advantages in stability and portability.
