Is a Monocycle something different to a Unicycle?

Apparently! I did not expect such a nice find after asking search engine this: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1700041 > 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.

But I also bike because I enjoy it, not because I’m trying to get somewhere fast. You seem to assume that because this thing is faster, it must automatically be less enjoyable. That’s not the case for bikes, why should it be the case here? In my opinion it sounds fun, and…

Maybe not necessarily "faster" but there is an idea that adding any kind of technology should be avoided for recreational activities. For example, you can mountain bike with a fully-suspended e-bike, or you can struggle with a hardtail or even a road bike. Different kinds of fun, but in the former you'll wonder if it's the technology doing all the work.

Peak efficiency probably looks like this: https://newatlas.com/marine/jetcycle-hydrofoil-pedal-bike/

That looks absolutely amazing. Super cool that you can maintain elevation at less than 6 MPH — I was expecting it to be closer to 10 or 15 MPH.

It has been a while since I was a competitive swimmer (AAA+) but imho five minutes is a very good time for 500m. That would be faster than 95% of master swimmers at such distances, and well into the 0.01% of humans overall.

Ah shit your right, I had in mind 500 (yard) Free. 500 meters in under five is very good, but still attainable by the upper tier of highschool swimmers I think. I could reliably do 500 yards in under five and was a "B relay" tier on my team.

Yeah I think for most uses I would still prefer fins for their agility. Cool idea though, and we probably haven't seen peak efficiency here.
