dpc1192,

Clearly, you are taking a little (not too much really) flack over your question. I'd ask you to take a close look at what you are asking and you'll quickly see why. Asking for the cheapest possible fixed clearly implies (not necessarily true but certainly implies) that you are looking for a fashion statement, have done little or none of your own leg work and beyond that your personal safety is secondary. You gave no details such as price range, you are asking people who don't know you at all and to fit you over the internet with a single given dimension (height) - which clearly shows you know little to nothing about how to correctly fit yourself on a bicycle. On and on.

I'm not taking cheap shots at you. I'm pointing out that you have no right to expect people to just do all of this for you and have them thank you for the question. Helping is one thing but doing everything for you is another. To put a fine point on it - you are being incredibly presumptuous (another way of saying that is "rude") and vaguely insulting. If you did not intend to be then I suggest posting a reasonable "oops" (everyone will accept that) and try to be more specific/give more details about what you want. Or, go to your local bike shop, talk with them and get their advice. Do not be afraid to make your first question about their awareness of used bikes they sell or are aware of in the area. You can appropriately imply you are new to the area or to cycling and just looking to get on board. Be honest, direct and reasonably humble. They will help you as they will someone who as time goes on will drop coin in their shop. That's really the proper way to go. Spend your money locally and engage the local professionals as much as possible. You will be helping them keep their jobs and you'll end up with a better product. Win-win.
