Ever wondered what happens if you take a sidehack BMX down a trail? Well, thankfully Dylan Stark tried it and filmed it so you don't have to. There's a long intro section showing how the video came together but we've skipped straight to the bit with Metallica on the sound track and big crashes on the screen, this is pure carnage.

Drew and Luke push the limits of a new sport called SHDH ( Side Hack Down Hill) Let me know what you think in the comments this video was so much fun to make!"
