bmxTwo BMX riders bombed down the sloped side of a Rotterdam skyscraper for this video that’s surprisingly not preceded by the words, “Don’t try this at home.” After playing around in the dark on their glowing bikes, Mark Vos and Boy Janssen head for the roof of the Willemswerf building and drop down the steep face. Shot from several angles, it’s compelling footage but pretty suspect. After all, not even Jackie Chan pulled off that 5-story drop after his “Who Am I?” slide. Watch for yourself below.
