This year's Red Bull Ride & Style competition in San Franciso will forever be remembered as the day Japanese fixed-gear freestyle rider Kozo pulled off the first back flip to be done on a fixed-gear bike in competition, ever. What makes the feat even more amazing is that dude even did it with no straps on. The entire event looked like a ridiculous amount of fun, and anyone who was lucky enough to have been there that day caught a little bit of FGFS history being made.
