I live in Oklahoma which is nothing but a big hill made of smaller hills with potholes disguised as landmine fields. I would like some help trying to figure out what type of bicycle that I could put an 80cc motor on that would be powerful enough to take hills and not destroy the front tire when I hit a bump/pothole. I weigh 140 lbs. and am 5'5" if that helps on what type of bicycle. If you need more information please let me know I really would appreciate serious help.
