There is such a thing as floating cars, boats that drive on the road and now a floating bicycle.
The Amphibious Bike made by Li Wieguo was shown off at Naishahu Park in China. The bike is outfitted with 8 water gallons that allow it to float and the wheels have paddles attached to them to make it move.
If you want to take the bike out of the water, the water jugs can be raised up for easy riding. Li Wieguo is currently refining the design in hopes of mass production.
