I don't own a motorized bicycle yet, but I'm planning on getting a schwinn this upcoming weekend. I will slowly be converting it to a derringer style board track racer replica, and me being me, I want to see how much speed I can get out of a little 49cc 2 stroke engine I also want to install a disc brake on the front as a minimum, and I would really like to devise a way to install dual disc brakes up front. I'll use a standard 2 inch wide front tire, and the widest rear tire I can fit on the bike. I can't wait to start!
