When riding BMX learning to work on your bike is an absolute must so today we decided to do a video on fixing a flat tire something that happens all the time in the BMX world. For this video we decided to go two different ways we have BK a mechanic at my bike shop show you guys how a professional change the flat tire and we also have big boy who is not by any means a professional mechanic show you how he changes the flat tire! We figured that this way we can show you all what to do and what not to do when changing your flat tire! BK can change a flat in world record time big boy on the other hand Big Boy can manage to get a flat in world record time! In this video the guys take their own tools and show you exactly what they use them for and in big boy’s case even the Oreos and the helmet!
