Paul:
I've seen both Piccolo and Brompton side by size and the difference is not significant. I doubt the average bus or train conductor will be able to determine the difference in size and his/her opinion on allowing you to board will be based on other factors other than the 10 inch difference. The Piccolo is not 60% larger than the Brompton and this is obvious upon looking at them placed side by side. I happen to think Brompton and Dahon measured the size of their bikes based on the metal that sticks out the furtherest and not the actual size. Where the point is located from which they made their measurement is really unknown.
