yeah, i'm still doing some research as to what will be needed. If i can get this motor, change my gearing, and get everything running okay, then we'll see what it can do. If it hit's 80, I'll be happy. I just want it to be more realistic as a bike to take around town. hitting 50/55 around town isn't that spectacular, and i'm lucky to hit 45 up a hill, i couldn't imagine how it would be like that in heavy traffic.
