What happens when a mountain biker takes on the legendary Hahnenkamm downhill course on the back of his bike? That’s what Max Stöckl traveled to Austria to find out. As you’ll see in the video below, he got everything he could ask for, even hitting speeds as fast as 106 km/h (65 mph) in the process. This is one fast and wild ride down slopes that average a 27% gradient. Who says mountain bikers can’t have fun in the winter?
