Nanos are not for everyone, as the ride is very twitchy until you get used to it. I am 5'8" and ordered the larger frame size so as to extend the wheelbase and I am glad I did. I enjoy mine a lot and find popping off the wheels makes it easy to get into the back of a small car, obviously not as easy as a Brompton, but not too bad at all. BTW, one of the the things I love about the Brompton is the luggage block on the headset which sets the weight low and on the frame. I think I will try to figure a way to do the same on the Nano which may, as it does on the Brompton, actually smooth out the handling.
