It's a life long debate because like anything else there is no right answer. You like what you like. I wouldn't mind owning a Brompton but they are expensive. I love my Dahon and loved my tern when I had it. It's like those internet fanboys arguing over android and ios smartphones. I've had them both and I love my htc one but people swear by their iPhones so....whatever makes you happy. If you can, test ride many bikes. If you can't, do your research, be honest with yourself and plunk down some hard earned cash and enjoy the ride. Either way, sure beats a 5 year finance on a nicely equipped carolla.
