Completely redesigned for 2007, the Cadenza is a more grown-up Dahon offering than the Speed. Despite being one of the biggest machines here, it should fit in most boots, although it is not ideal for carrying. It’s a little awkward to fold, too, because a hex key is required. But it rides well, so the Cadenza is particularly suited to long commutes, thanks to its extended frame and 16 gears.
