The key lies in its revolutionary but very simple construction. Underwater wings provide stability and at the same time are responsible for motion, which allows to swim. You just have to push yourself on Pumpabike away from shore, a platform, a boat or any other on-water stable construction.

I would like to introduce Pumpabike. An ingenious machine, which is neither a bicycle nor a water jet, yet it is capable to run at amazing speeds propeled only by your own muscles! The key lies in its revolutionary but very simple construction. Underwater wings provide stability and at the same time are responsible for motion, which allows to swim. You just have to push yourself on Pumpabike away from shore, a platform, a boat or any other on-water stable construction. Having done that, all you need to do is to jump as if you were pumping... to move on water's surface up to 30km/h!
