Hi, I am in the process of getting started building up a motorized schwinn occ stingray. I have been looking online at some really nice builds and want to use the best of everything on my build but I don't know where to buy everything. A couple of main components I want for the bike is the motor mount adaptor, long drag pipe, hub adaptor and better brakes, preferably disc brakes for best stopping power. I have found a few of these items online but some of the prices seem a bit high and wondering if any of you know where I can buy these items and at a good price. Probably most important would be the brakes, I need to know what is the right size fitting for this bike and exactly what I'll need for the disc brakes. Thx chris.
