Note that they're only being rolled in one direction: because you can't roll backwards much (if at all) as the pedals will rotate and then lock against the folding hinge. At least the D3 and P8 series. This is a big deal: it makes manipulating the bike in tight spots surprisingly tough.
Second, a bump or two and the magnetic hinge comes undone and then all hell breaks loose.
In my opinion, my dahons cannot be rolled. They can be "rolled" sort of.
That is why you have to roll it with the front wheel. I have had the following Dahons: Jetstream P8, Speed D7, Curve D3, Curve SL, Vitesse D7; and I was able to roll all of them easily without the magnet coming lose (except for the Jetstream which did not have a magnet). The trickiest was the Curve SL since it had the ergon grips, which made contact with the wheels, but it was quickly solved by adjusting the stem riser correctly.
