A Downton or Bromptube could be interesting, especially if it had adjustable height bars and better brakes, like a Merc. Would have to see the details. At some point, though, most of us just have to stop buying bikes and stick with what we've got for a few years. Amazing how many makes and models there are now, that are worth considering. And yet, since I got my first folder in 1995, I think I've only encountered one other folder rider outside of New York City.
