All this talk about small wheels doesn't change the fact that really small-wheeled bikes such as the CarryMe are a pain to use for medium to long range commutes. At least here in NYC. I tried one, and it was too tedious and uncomfortable, not too mention much slower than my Brompton or 26" or 700c wheeled bikes. Oh, and yes and the bike sucks when hitting potholes. No amount of theoretical analyses can overturn that experience.

I look forward to the folder chain lubing myth busters thread.
