I've unicycled for the last few years, and I haven't ridden anything else during that time. But lately I've had an itching to buy a road-bike. I've heard about fixies, and I figure it would be easy to transfer from a unicycle to one. I know nothing about bikes. So, if anyone could help me out on getting started, and choosing a bike, that would be great. A flip-flop hub sounds like it would be a nice medium. But I don't know where to begin, and I don't think any of the dealers around me sell fixed-gear bikes, so I'll probably have to make one myself.
