This bike lets you ride on water. The Manta5 is a hydrofoil water bike and it’s powered by a 400-watt motor. You can pedal on a river, lake, or ocean. Here’s how it works. The hydrofoils let you cut through the water with ease. It’s the same technology used by the fastest sailboats. You decide how fast you go with electric pedals, or you can pedal manually. A propeller moves it forward like a boat. The bike’s top speed is 12 mph and the battery lasts one hour. Would you pedal on water?
