Re: Hello from NE Tennessee!
Welcome to the forum. You can go simple single speed with a motorized bike and make it up extremely steep hills if it's set up right. First unless you are going shift kit for sure, and they are awesome a beach cruiser will transfer power and climb a lot better than the mountain bikes. We have built a lot of Huffy and Schwinn cruisers and with a healthy 66cc you will climb just about any hill. If you need any help feel free to pm me questions and I can help you with a great set up for hills. And remember you have to deal with down hill if you are dealing with uphill so don't forget the brakes!
