Abstract
The Trike's unique power source is provided by a rowing-type motion of the user rather than the less efficient 'hand rim' grip or wrist propulsion. The rowing motion significantly reduces the chances for repetitive stress injuries, like carpal tunnel. Furthermore, the rowing motion and movements, are designed to facilitate efficient propulsion and steering in combination, to be effected simultaneously. The rowing motion allows the user's full arm strength and full range of motion to assist in the powering of the vehicle. The wheelchair also has a retractable fifth or propulsion wheel that allows the chair to be used in a confined space without sacrificing performance.
