Brutal Urban Downhill Mountain Bike in Morro Santa Marta – Rio de Janeiro, Brazil. This is purely for fun, especially these days in which those downhill mountain bike rides are so popular. I think the source of the video clip is Root Rider Teve. Riders race though the winding paths and over the roofs of the Favela Dona Marta at the foot of Morro Santa Marta in Rio de Janeiro. The course of 800m descended 170 vertical meters with plenty of jumps. The favela community really enjoy the event.
