BMX star Mickael Dupont has figured out how to become the star of a viral video: perform his incredible freestyle stunts on a rickety vintage women’s bike. The video through Monday had garnered nearly 900,000 views. It’s a bit long but the tricks — jumps, tire spins, ramp and rail maneuvers, etc. — get better as the video progresses. It culminates with a back flip executed with no helmet. Kids, if you find your mom’s rusty old bike in the garage, don’t try any of this at home.
