ABSTRACT:
An amphibious vehicle has a hull with a seat portion formed on its upper side. An operator seated upon the seat would straddle the hull. The hull has a flotation body for buoyancy and four hollow, cylindrical wheels also contribute to the buoyancy. Handlebars are used to steer the wheels and to operate a rudder so that the amphibious vehicle may be operated on firm, sandy, soft, and liquid surfaces. The wheels have vanes which radiate outwardly and curve counterclockwise, viewing each wheel in the foreground and the hull in the background. This causes the vaned wheels to grip soil or mud and to channel water rearwardly to propel the amphibious vehicle forwardly. The vehicle is propelled by a pedaling mechanism.
