An amphibious cycle is a human-powered vehicle capable of operation on both land and water. The design which has probably received the most coverage is Saidullah’s Bicycle.[1][2] The bike uses four rectangular air filled floats for buoyancy, and is propelled using two fan blades which have been attached to the spokes. Moraga’s Cyclo Amphibious [3] uses a simple tricycle frame to support three floaters which provide both the floatation and thrust. The wings on the powered wheels propel the vehicle in a similar way to a paddle wheel.
Another design is the SBK Engineering Shuttle-Bike. It consists of 2 inflatable floats with straps that allow the carrying of a bicycle with passenger. The ensemble, when deflated, fits in a backpack for carrying by the cyclist.[4]
Another amphibious vehicle, is that of seven engineering students at the University of Southampton.[5][6] The Amphibious Cycle combines a recumbent frame with separate floats, and is propelled using a paddle wheel. A speed test on water achieved an average speed of 1.12 m/s. The cyclist was able to transition the cycle both into and out of the water unassisted. This prototype has a real application in urban areas of flooding, as well as applications in the leisure industry.
An amphibious vehicle was created by five engineering students at Calvin College as a senior design project (May 2010). This vehicle improves upon previous designs by allowing smooth transition from water to land.[7]
