For those who love jet skis as well as basic water skiing, the Pumpabike could help with your insatiable appetite for an adrenaline rush. This vehicle is a highly manoeverable and light machine without any large components that could cause serious injury.

All it needs is a minimum water depth of a mere 50cm for you to take it out on a spin. The Pumpabike propels itself (along with you, of course) by the motion of the rider jumping up and down just like a kangaroo - so make sure you’re in a decent physical shape before you venture out too far, as you might run out of enery to head back to shore.

Rhythm is king here as losing it will send you into the water without a moment’s notice. The Pumpabike is available to outdoor enthusiasts for £449.00.
