I imagine guys were doing this sort of stuff back in 1910 or so, which eventually became artistic cycling. Then BMX reinvented the sport, but with smaller wheels and a more anarchist style. True artistic cyclists put these guys to shame, as do most BMXers. Now these guys are just imitating BMXers, but on a bike more like those of artistic cyclists. Hell, even I was doing these very basic tricks back in 1987 on a Haro Master. When these guys start wearing leotards and spinning synchronous circles on one wheel to classical music, with a gear ratio less than 1, the sport of bicycle-trick-riding will have come full circle.

Its just all about having fun though, so no hate coming from me. But its certainly nothing to get excited about either.
