Hydrofoils are the fastest water-based vehicles propelled solely by human power. They can reach speeds of up to 34 km/h (21 mph; 18 kn), easily exceeding the world records set by competitive rowing which stand at about 20 km/h (12 mph; 11 kn).
How fast can you go on a pedal bike?
With medium effort a cyclist can pedal 8 – 10 KPH up a gentle incline. Riding on grass, sand, mud, or snow will also slow a rider down. Without pedaling downhill a bicycle rider can easily reach speeds of 20 – 40 kilometers per hour down a gentle %5 slope and dangerous speeds exceeding 50 KPH on steeper inclines.
What is the fastest hydrofoil?

What is a water bike called?
A hydrocycle is a bicycle-like watercraft. The concept was known in the 1870s under the title ‘water velocipede’ and the name was in use by the late 1890s. Power is collected from the rider via a crank with pedals, as on a bicycle, and delivered to the water or the air via a propeller.
