Re: Hello from Kentucky
Welcome butchatron, I know you'll enjoy what is offered here. This is the BEST place to come for help, so cry all you want. We're glad you've decided to step up and get into the world of Motorized Bicycles. It's a great hobby full of interesting and knowlegable folks.
If I could make one suggestion while you're still in the planning stages, seriously consider adding front brakes to your bike. I know you said you want 'old school' but the old bikes didn't have engines that could push them to speeds approaching, and sometimes surpassing 30MPH. With the added weight of an engine and accessories a single coaster brake can be just a little light in the stopping department. Keep us informed on your progress.
