C.IMChuck Darwin (@cdarwin@c.im)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...
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.
