Human Powered Hydrofoil

To look at the Pump-a-bike, you’d swear it would sink the moment it hit
the water. Not so, indeed, with a bit of practice, the human powered
hydrofoil is capable of nearly 20 miles per hour – not that much shy of
the world record for human powered watercraft
. To make it work, all you need to do is jump up and down. Given some
time to coordinate the movements and gain a degree of mastery, the
Pump-a-bike can even be used in surf to ride waves. Great photos.

Not as strenuous as it looks, but a bundle of fun.

Still hard to believe it works, but it does

Constructed of aluminium and plastic, the hydrofoil weighs just 14 kilograms.

Launching needs a platform of some sort – any steady platform will do.

Unlike any other water craft, the hydrofoil comes apart and can be transported in a small bag.

Pumpabike’s Simple Operating Procedures:

  1. Hold the bike over the edge of the water with the big wing just touching the water.
  2. Place one foot in the toe strap while holding the handle bar.
  3. When ready, roll forward in order to place the front (small) wing into the water.
  4. Then the most important step: In a very smooth action, push the bike
    hard away from the side. This will make you “take off” like an airplane
    and start to “fly”.
  5. Once the bike is “flying”, you then start to bounce up and down in the toe straps. This will propel the Pumpabike forward.
  6. Once “flying”, it is important to keep the wings in a horizontal plane.
    Do this by keeping your body centralized. To correct any sideways roll,
    simply move your body to counter this roll.
  7. Enjoy the ride and come back to land carefully so that the bike will not be damaged on rocks or similar objects.
