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. 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 uses a simple tricycle frame to support three floaters which provide both the flotation and thrust. The wings on the powered wheels propel the vehicle in a similar way to a paddle wheel.
