I need to see a physician to uncover the root of my problem. I've had trouble riding geared bikes though. I absolutely hate them. It might be something personal from when I was a kid though. I don't know for myself.

Well there is someone selling this http://sfbay.craigslist.org/sby/bik/2919921566.html and I was wondering if it's something good to start with? Also is the price ok or should I negotiate?
