ABSTRACT:
An amphibious bicycle intended to be highly efficient, safe and maneuverable forms of both land and water transportation. This achieved by the addition of a strong, rigid frame work, small paddles in the rear wheel assembly, and durable, nonsinkable pontoons of high density styrofoam, made structurally strong and protected by linear outside structural supports sandwiching them. And finally, adding bracing at strategic points to effectively maintain the pontoons' land or water position.
