It would of course be much better to compare a Dahon Piccolo D3 with a Dahon Vitesse D3.

The Speed 8 is superior of the Piccolo for many other reasons than only the 4" wheel difference.

I've carried my Presto Lite in a Double-play bag a lot - On ferries, underground, buses, trains. Transported it with accessories on Airlines in a 29" bag. Had it folded in the back of my tiny Seat Arosa car. I've always wished for the package to be smaller and lighter, never the opposite.
