The creators of the Hydrobike claim that their water bike is the fastest and most efficient in the world.
The pedals power a propeller that can bring a rider to cruising speeds of 4-6 mph, and a top speed of 10 mph.
It's quiet, stable, and can be used on most bodies of water.
The Hydrobike can be used for fun, exercise, or even for transportation purposes.
