Our friends at Red Bull just sent us this video, and it's so cool that we just had to share it with our Cycle World family. The video features freestyle motocrosser Ronnie Renner and friends, tearing into some fresh British Columbia powder on their snow bikes. Don't know what a snow bike is? It's basically a motocross bike with a rear wheel that has been replaced by a snowmobile track. And in front, there's a ski instead of a tire. And it's flat-out amazing what a talented rider like Renner can do on such a machine. Enjoy!
