French company Seabike has developed a swimming device that uses your own leg power to accelerate you through the water at superhuman speeds. This crank-driven pusher prop looks a bit like an underwater unicycle... We'd love to take one for a spin!

I can't say I've seen anything like this "underwater mobility device" before. The idea is simple enough; you extend the Seabike's pole to the appropriate length, then strap it to your waist with a belt. Then you find the pedals with your feet, and start turning the crank, with the waist strap to push against.

This drives what looks like about a 15-inch (38-cm) propeller. At this point, you start gliding through the water with the splendid, gracious ease of a cruising dugong with an outboard up its bum. You can swim with your arms as well, which creates a surreal visual effect somewhat akin to watching somebody walking along an airport travelator:

Or you can laze along, arms held out Superman-style. Or indeed, you can angle your nose down, go fully underwater and make like a pedal-powered fish. It's fully compatible with a SCUBA setup if you want to really go nuts down there, although you wouldn't want to take it down too deep and overexert yourself.




Awesome!
