This is a video of BMX biker Pat Lauglin transferring from one bike to another after launching himself off a ramp. There are actually two videos after the jump -- one really short one of just the successful attempt, and a much longer one of all the failed attempts it took before he got the trick down. Not everybody can do everything perfect on the first try you know. You think the Hulk always remembers his lines in those Avengers movies? "Hulk is computer generated." HULK IS A FRIEND OF MINE AND WE WILL CRUSH YOU. Also, this looks like a really great way to do irreparable damage to your nuts.
Keep going for the videos.
