As noted earlier, if you are of average height, there is a plethora of very acceptable folders to choose from. If you are 6'2"-6'3" or taller, there are only a couple of 'comfortable' fitting bikes.

I recently tried out a friends new Tern - very nice bike, but just too short a cockpit for me, and the max seat height was a bit short. If I want to confirm how 'inadequate' most folders are for me, all I have to do is get on either of my Fridays. My city bike (the Bikes Direct Windsor) is a bit small for me, but was inexpensive and works very well for the 1-4 mile shopping trips we go on.

If I had to purchase a small-fold bike for train trips (which I/we might do in the future) I'd basically have two choices in the fit and quality range I would want - a Brompton or a tikit. Luckily, because we are spending our daughter's inheritance, we can afford either.

Note: We started with inexpensive 2005 Dahon Boardwalks (both a D7 & S1 for me). They were good bikes, folded better than the Fridays, but not as comfortable, capable, or as easily upgraded parts wise.
