> The nominal mode enables motion through the water at 3.6 km/h, and for speed-seekers, the SEABIKE can reach a maximum of 7.9 km/h – much faster than normal swimming speeds or even flipper-assisted swimming. https://www.nauticexpo.com/prod/seabike/product-68606-564117... Pretty fast, but "superhuman"? For short distances Michael Phelps can swim faster :)
Michael Phelps is an alien..
'Underwater bicycle' propels swimmers forward at superhuman speed

#92Cool. More like an underwater 'monocycle', though. Make it into a full body struct in Y shape acting as kind of both 'guidon' and secondary propulsion axis -- more blades, an underwater tricycle. :)
Is a Monocycle something different to a Unicycle?

> There are two main types of single-wheeled vehicles. In a unicycle, the rider sits above the wheel. These vehicles are recognizable by most people. Less well known is the monocycle, where the rider sits inside the wheel.

#93It’s obscure but there was such a contraption trialled by the seals and cia in the 1950s http://www.hisutton.com/CIA_Water-Air_1958.html Here’s a pedal powered smuggling submarine from the 1940s http://www.hisutton.com/Swiss-Pedal-Powered-Smuggling-Submar...

#97I swim because I enjoy it, not because I'm trying to get somewhere fast. This seems awkward and I bet you have to use your arms just to counterbalance the twist you'd get on each 'stroke' of the leg. So even though I think it's goofy, I bet I'd like whoever came up with this. Someone who put a ton of effort into building something they thought would be interesting despite a thousand people telling them it's goofy. Go…
Balancing this device must have been a good problem to solve! All I can think of is “where does the other end that stick go?”

#98What's the advantage of this over foot fins?
I live near a fairly dangerous ocean in SF where I’ve gone bodyboarding with a wetsuit and fins. I’m concerned that, if caught in a current, fins are not enough to propel me out of it.
This would. The extra power and ease of propulsion could make all the difference.

#100Seems prime for attaching to a surfboard
Another interesting use case would be just tossing one of these into a boat that you own, or a kayak or whatever. Basically extra insurance to get you back in case your motor dies or you get swept out, similar use case as the surfboard
