(above) You're right, on a big-buck folder, I do expect 400% gear range, or at the very least, ability to get there easy. I recommended to the Origami Bull seller on here, that since it comes with an FD bracket, he should offer it with 2X, because it would offer much greater value to the buyer than it would cost for it to come factory that way. 1X is a great option these days as you've proven, but 20" makers seem to limit themselves to 34T RDs, but that may change.

I normally have high standards for value in what I buy, but that can be hard if *no one* offers what I want at reasonable cost. Dahon has had the offerings at times, but charged ridiculous multiples in price for discs and 2X (Formula 18) which added, what, at most USD$200 to the bike cost? That bike had stellar reviews, but didn't sell due to the price, like 3X that of a Mariner, IIRC.
