Re: New guy from AZ
I live in Kingman and have just what you described. A 48cc on a mountain bike. The 48cc rocks since there are virtually no restrictions as far as licensing are concerned. It is a BICYCLE pure and simple. State law 28-2516 says it all. It does have a word about speed. it says 20 miles per hour limit BUT does not say whether this is only under power or at any time. I'll have to look for that answer. I don't know where you are but there seems to be a bit of bias towards motorized bikes in some towns. The regulars on the board can help you BIG time. Welcome aboard.
