I've been riding a Brompton this last week and actually it feels 'squirrelly' compared to both my Dahon Vitesse and Curve SL. The handling is entirely different. So far I think the Curve SL with Thudbuster is a better ride despite its shorter wheelbase; certainly in terms of componentry (and aesthetics) it's miles ahead. I'm going to sell one bike at some stage and I don't know yet which, it all depends on the Brompton's shopping cart ability and how easy it is to take into shops. In terms of wheeling through stations I'm not sold on the Brompton yet; one has to unfold the handlebars in order to pull the bike whereas with Dahons I can have things set up so that wheeling is easy in a fully-folded position.
