'Underwater bicycle' propels swimmers forward at superhuman speed
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!

seems a little bit scary being clipped into the contraption. maybe not as bad if scuba is involved. but what if the mechanism fails or gets snagged while you’re clipped to it?
You unclip, same as with a bicycle.
What bicycles require you to be strapped into them?
Clipping into pedals is pretty common actually (which is actually called clipless despite having clips), at least with road bikes and racing. The idea is clipping your shoe to the pedal makes your pedaling more efficient.
Personally, I prefer flats in case I need to hop off quickly, like if I'm about to get hit by some dipshit in an SUV.
Mountain biking too.
I prefer flats too but most pro downhill and enduro riders use clipless.
That's why I asked, I've never seen anyone do it before. Pretty much for exactly that reason.
I would never ride without being clipped in, maybe 100 yards to the shop and back but other then that clipless is much much better. Used then for about 20 yeaes now. Took about 2 weeks to get used to from memory.
It's definitely common among more hardcore/serious cyclists.
I rode clipless pedals for mountain bike racing (cross country). It is so much more efficient and they have shoes with thicker soles and deep treads which makes them more comfortable to walk in.
They also make jumping over small obstacles and rocks easier and safer.
Yep. I just use the clips with the smallest degree of pop out...works great and I never noticed being "delayed" to get my foot out and onto the ground if I need it. Even in some VERY time sensitive situations
Any bike with clipped pedals???
I've never seen one???
hard to imagine it’s truly the same. would be interested to see the process
They probably rotate their foot 45° to lock and unlock.
aha i just saw the “seat”. guess thats what makes it possible
You thought the thing was just entirely untethered?
i hadn’t seen the seat, just the clipped-in feet.
when its underway i guess the “seat” lets you steer (with your thighs) a bit and gives a point of leverage for the unclipping (especially when its the singleton clip/unclip).
not sure why, but it all seems a bit inelegant. but if it multiplies effort anywhere near what a bike can do, that’s a big achievement.
There's a clip of a swimmer doing it without shoes/clips so maybe they're optional.
