Cities are great for bikes becasue they are probably the easiest form of transportation (and cheapest), as well as more maneuverable. While in my euphoria of seeing all these bikes in downtown Chicago unknowingly I captured a rare sight, a mountain bike being used as a city bike. I doubt it's an actual 29er, if it were I would probably go into ecstactic shock, but looking at this bike in more detail it looks like a mountain bike outfited with 700c wheels and probably a 40c tire. What's really interesting, however, it the fork choice. While it could be just about any brand, this definitely looks like a carbon fork.
