Re: Frame or Back mount???
I agree with bikeguy joe. I have both a 66cc china girl in frame and a thatsdax rack mount friction drive with his xc50s. The 4 cycle xc50s is quiet has plenty of get up and go and the friction drive was a breeze to set up. Took about an hour and a half and I was taking my time with it. Maintainance is as easy as checking a few nuts and bolts, tire pressure, and chainging your oil on time. For ease of use go with a quality rack mount and 4 stroke motor.
