Here's another
It's belt-driven. I test road one at the NYC bike show. I had never been on a folder / 20" bike at the time and it was reasonably comfortable. Several months now of Dahon ownership have passed and I think I'd really dig it now if I tried it again. I also tried a shaft-driven bike at the show, but it was full sized. It looks like the one in the OP is a shafter.

I was under the impression that this bike was not belt driven (like the Strida, as an example). I seems that it has a direct transmission using a spinning axel, directly connected to the center of the rear hub (or really close to it).
Looks funny though, but must be a convenience for your greasy hands.

It looks like a Sussex chainless shaftdrive conversion. I'm looking to convert my Dahon Speed P8 folder with it. If you're interested in chainless shaftdrives, see FAQ section at https://www.dynamicbicycles.com. They don't mention anything about how difficult it is to remove the rear wheel.

it may be wacky, but it will also be the succedaneum of the traditional products.

so far all shaft driven bicycles had a 20 % or more powerloss versus chain.....
I think if you use ceramic coated gears and unobtainium parts, one could make it go down to 15 % but thats it....
On a big BMW motorcycle or high power quads shaft drive can be of some advantage, although I would also prefer a chain......
