Amphibious cycle

"[1][2] The bike uses four rectangular air filled floats for buoyancy which propelled using two fan blades which were attached to the spokes.

"Moraga’s Cyclo Amphibious" [3] uses a simple tricycle frame to support three floaters which provide both the flotation and thrust.

[5][6] The "Amphibious Cycle" combines a recumbent frame with separate floats, and is propelled using a paddle wheel.

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.
