I'm all for diversity, as long as we're talking bikes which aren't Pareto-dominated. Sheldon Brown (may he rest in peace) championed the R20 because it was *non*-dominated. That is, there was no bike which was superior to it in all aspects (including price). So it had a niche. But the BigFish is entirely pareto-dominated by a whole host of folding bikes.
So let's restrict ourselves to just bikes of the same wheel size and approximate wheelbase Can you name a single reason why anyone,
anyone, would prefer this hunk of junk over a
Dahon Curve SL? The Curve has better support, costs less, is lighter and better constructed, has far better gearing and components, and folds much much MUCH better. And it doesn't have junk brakes.
Heck, how about just a Dahon Curve D3, at half the price of the BigFish and still superior to it? Geez.
As to
Dahon Girls....
