Wheels of Steel

Anyone got any idea what this is, other than the obvious? I was sent the pictures without any background or explanation at all.

I did try searching for it on the interweb and drew a blank. Funnily enough I didn't get very far when looking up 'weird bicycle with loopy metal wheels'.

Proud Owner or Mad Inventor?

It could be a ‘design’ thing, a serious attempt to run a bicycle without a tyre (in which case I don't imagine that they will be too popular in areas with cobbled streets), or simply an interesting piece of kinetic sculpture. Your guess is as good as mine.
