15 Historical Photos You Won't Believe Are Real
14. Cyclomer - The Amphibious Floating Bike From The 1930s
A human-powered amphibious cycle may still seem like something of the distant future - yet in the 1930s they had already been invented.
This photo shows a man in Paris riding the "Cyclomer" in 1932 - an amphibious push bike that could float due to the fact it had buoys as wheels and also attached to both the front and back.
It seems unlikely that any fashion-conscious person would be seen dead riding one of these though...
