Speedy's bump 2 ledge grind was modded, it's impossible to wiggle the bike that fast in mid-air without tinkering with the gravity. If you don't believe me try doing it yourself..
Other than that the stunts were nice, the editing could do with some polishing (I'm not a fan of weird shaking/moving effects like the ones used here), but it's more important how much you guys had making the video right
