Urban downhill is an extreme form of downhill bicycle racing in which participants race through urban street environments not originally designed for bikes of any kind. Racing down steep flights of stairs, jumping over walls, flying through public courtyards, and even cutting through people’s houses, the videos you see here are shot in Chile, Mexico, and Peru and they feature some of the gnarliest urban downhill race courses in the world. Check them out… and I think you’ll see what I mean.
