You should never mountain bike with a 20 inch wheel which is why Dahon never made one that size. It's too dangerous and uncomfortable for mountain biking. I have a 20 inch wheel bike and it's less comfortable than a 26' or 27' inch tire by far. Furthermore, the smaller tires slips into cracks and pot holes which makes riding more dangerous at night or even during the day. Trust me.. I have a battle scars from falling off my folding bikes. Last, the smaller tire (especially the rear wheel) wears out faster than a 700 cc tire.
The 20' inch wheel is far from perfect.
