well, i've decided to bite the bullet and save up for a used brompton... its not just that they can be rolled easily when folded, they also fold down into the tiniest size. and thats *very* helpful for a commuter who has to occasionally ride the bus or train. I basically never want to have to leave it locked up outside on the street, I want it with me at all times (indoors, outdoors etc). Thats when its most useful to me, if I can do that. They get stolen so easily...

and in that regard it looks like bromptons are the easiest to 'live with', cuz you can put that cover on them and just walk into any restaurant or store or bus and it just looks like a small suitcase. No one even has to know. And can even drag it behind you as a 'suitcase' with the cover on it. That appeals to me a lot cuz that way I never have to leave it anywhere, I can just take it indoors even in public.

regarding rolling it tho -- thanks for the tips and videos. Looks like some dahons can indeed be rolled (mu uno, curve d3, etc) based on youtube videos. Tikit is interesting with its rolling rack. But even these dont fold up as compactly as the brompton. Strida's look funny, I dont think i'd want to ride those, even tho they fold up and roll really nicely.

So yea, time to save up...
