This guy simply know how to ride it. Take a look by yourself at that such clean tricks, one by one. Also there are some difficult. But it is not important to know super hard combos. For me is better to ride every obstacle in clean easy style than in sketchy hard tricks. Most important is how you can enjoy your riding. I like simple style, chill out, clean tricks and no sketchy tricks. Is that hard? No, everyone can ride like that.
