I'm no math genius, but comfortable enough with numbers to become an engineer. I don't get it - when I see this:

"Pivoting on helical hinges, the two 24-inch wheels fold in against either side of the one-piece main frame and sit between the cranks. Once the handlebars have also been folded down, the seat lowered and the pedals flipped in, the end result is a package that measures 23 × 25 × 9 inches (584 x 635 x 229 mm). It's only slightly wider than the crankset, and not much bigger than the wheels."

I wonder how a 24" wheel can fit within a 23" x 25" area - never mind that the picture of the folded bike shows it extending beyond the bicycle rim in both horizontal and vertical dimensions.

As for it folding smaller than any other bicycle, perhaps Mr. B should edit that to read "I t folds smaller than any other bicycle that Mr. B is aware of.
