Re: Hey all from NW Arkansas in the Ozarks ... This is going to be fun!
Welcome to the community, Sinner. You've come to the right place to get started with your first motorized bike project.
Your choice of the Panama Jack is okay. Many have been motorized by members here. Try typing 'Panama Jack' into the 'Search' box and you'll have some reading to do about that particular bike.
For hilly terrain you might want to explore installing a larger rear sprocket than comes in some kits. Typically we recommend something in the 40 tooth range but for better hill climbing performance you might want to go to a 44, 48 or even bigger if you're a big guy. This will slow down your top speed but will help you over those Ozark hills.
Good luck and we're always here to offer help, advice and assistance if/when you need it.
