Dude, that's pretty hype, I just built my own motorized bicycle recently, except mine is a 1000W electric Bike, but im interested, how fast have you gotten yours to go? Just wanna compare the gas vs electric speed.
Great video, dude! What size sprocket are you using on the back wheel? Mine can't go that fast : ( Also the air filter mod seems pretty good but won't it restrict the airflow too much?
