Lego - Free wheel system for bikes

Hi there! I've been using this system for a while in some of my cars but i never thought about how good it would be on a bike. So here's my test before i start messing with an actual bike. It works pretty well, i had to cheat a little bit cutting a 3L into 3 bits of half stud to strenghten the rubber parts in the clutch. It will basically allow the bike run free from the motor, wich means that it won't fall down as soon as you release the power button. HOPEFULLY :D
