The 1932 Cyclomer amphibious bicycle

In 1932 a French inventor unveiled his amphibious bicycle, called the cyclomer, at a Paris exhibition. He demonstrated its unique ability by riding it across a swimming pool. In the photo above, it is in its land mode. The wheels are hollow, providing buoyancy for crossing water. The four smaller spheres are on arms that can be lowered to the side. These provide additional buoyancy and stability. If you look closely at the back wheel, you can see small triangular projections. These act as paddles to propel the bike forward on the water.
