DO NOT USE RED BULL AND STUFF, it's stupid if your tyred and you use red bull it can realy f**k you up, especially the younger riders out there, it's not good, especialy if you go out every night loaded on energy drinks. maybe if you have comps or something but it will leave u totally drained and stuff. also if you are tyred, DON'T ride, your f**king stupid to ride if your tyred i not got all the little facts but you ask a doctor or anything, you can uber do yourself in!
