1. My Surly Cross Check. It's so very useful and so mod-able. Actually, it is currently the only good bike I can afford. Really annoying when it breaks down beyond-my-ability-to-fix and I have to wait for LBS (like right now).
2. Brompton. Travel and multimodal commute. 6-gear cuz my wife's fam. lives in mountain country.
3. A nice Raleigh DL-1. If you have to ask....
4. Pashley Roadster Sovereign, for winter and transport.
5. Rivendell Bombadil. If your gonna mountain bike, do it in style.
Never abandon style for function, or the other way round. Life is balance, don't go to extremes.
