A Bike Flip on a Moving Train

Here's a bike stunt that has never been done before, either because no one thought to do it, and if they did, they couldn't afford to make it happen. Enter Red Bull. Polish cyclist and world champion Dawid Godziek will show us some bike tricks including a flip on a moving train. He and his brother Szymon Godziek designed and built the run on top of ten cars from the Polish State Railways. The locomotive here is high-tech and can maintain a steady slow speed in order to load cargo from hoppers without stopping and starting. That allows Dawid to get used to the physics of performing on a moving train, and helps keep him in the shot. (via Metafilter)
