I just introduced myself in the introductions thread, and I hate to be that guy who's first post is a question, but here goes!
My past biking experience is as follows, it's not much. A few years ago I assembled a 10 speed road bike from parts at the "Boise Bicycle Project." I got sick of the poor comfort factor of that particular road bike so I went to the opposite extreme and bought a nice electra cruiser which I am now wanting to sell because I am moving and need a faster commuter. I commute on paved roads, side walks, snow(sometimes), ice (sometimes), maybe even some dirt, and go over curbs, hills, and flats. Because of this I do not think a standard road bike is for me. I want something I can commute with in all seasons (reasonably fast), granted I might have to use studded tires. What is my best bet? I don't need suspension. Is it a good idea to use a suspensionless mountain bike frame and slap some street tires on it for speed? I am open/interested in 29 inch bikes as well as fat bikes (maybe, out of my price range probably) but I have a $500 or less budget. I can build or buy. I just want a dead reliable bike that I can knock around a bit. What say the experts?
