  • Aerodynamic amphibious recumbent cycle and kayak
    Patent number: 9533536
    Abstract: A human powered aerodynamic amphibious recumbent vehicle having an outer shell that operates as the cycle exoskeleton, aerodynamic fairing, and boat hull. The vehicle includes a propulsion design adding paddles to the front drive wheels or pairing traditional pedaling to a propeller mounted on a kayak rudder via a flexible axle. Composite materials are used to form the vehicle and allow it to remain lightweight, abrasion tolerant, structurally rigid under rigorous operating conditions, and waterproof. The vehicle can enter and exit the water by riding directly in and out, or can be lifted by one person safely.
