Marcin Wroblewski is one crazy, Polish BMXer. But even he had a hard time making this edit. He injured knee ligaments twice, went to the hospital a hand-full of times for assorted bumps and cuts, and left a lot of blood on the asphalt. But, as they say, it's a long way to the top if you want to rock and roll. And if we had only three words to describe Marcin, we'd use "rock and roll".

When you combine his fearless riding with an old school rock song performed by him and his dad, you have one unforgettable video. 2 Injured Ligaments, A lot of Blood, and One Awesome BMX Edit | Welcome to Poland, Ep. 5
