The problem is in having a single speed capable of both 30+ cruising speeds along with hill climbing capability. Depends to on the grade and length of hills... a long steep climb takes either lower gearing (bigger rear sprocket) or more power. A bigger rear sprocket is at the sacrifice of top end cruising speed. How big a guy are you? Will you be pulling a trailer?
Thanks for the point of proper gearing. It's mostly long steep gradual hills. The top end isn't so important. I mostly want to enjoy the ride. I mostly have to pack work clothes and tools in my panniers - nothing more than when riding my bike. I weigh about 170.
