Everyone knows that BK is a master when it comes to tail whips and everyone also knows that he is the mechanic at my bike shop! People constantly come in to have BK work on their bikes because he is one of the best there is! Today we are going to see just how fast BK is when it comes to building up a BMX bike! I challenged BK to a build off! We both start off with the same bike and build it from scratch and then you have to complete a bunny hop tail whip on the bike that you just built! I might have bit off more than i can chew on this one! Follow me @SCOTTYCRANMER and remember to SUBSCRIBE!
