Hello Jerry, welcome the forum. Glad to have you with us, a great bunch of peolpe here with lot's of knowledge.

I have gone up a 9,000ft mountain in 19miles on a 36t sprocket. Had to do a little pedaling in some spots but it was a breeze. I have a 80cc two-stroke and I've been very happy with it.
I've been saving over a thousand dollars a year in fuel cost riding my motorized bike. They pay for themselfs real fast.
