ABSTRACT:
A personal traction transportation vehicle which includes two gear-motor-wheels which drive a connected chassis forward. The chassis is stabilized by a third trailing caster wheel. The vehicle is electrically driven by a removable battery pack. At least one and preferably two drag poles simulating ski poles are attached to the chassis through universal joints in a manner allowing the handles of the ski poles to be free to move in the plane normal to the direction of forward movement. The vehicle is steered by either twisting the poles which turn the front two wheels, or by motoring the front drive wheels independently, or by differentially pulling on the drag poles.
