Liang, please post photos of the new BF. And, how small does it fold? Do you know if BF folders fold as small or smaller than Dahons?
Curious: I notice the greater ease of “roll-over” of our wide pavement expansion cracks with 29er tires (~29” tall with 50+ mm tires) compared to 26” 42s at 25 3/10” tall, and certainly compared to 24 1/2” tall wheels with 26X1.1” (559X28 mm) tires. I am very curious to learn how a 20” wheel rolls smoothly over bad pavement. What tires do you use? Of course, tire width, inflation pressure, and casing quality matter almost as much or unqualifiedly as much as diameter, IME; but I do find myself being much more careful riding over a 10” expansion crack with 28 mm 24.5” tires at 55/60 (otherwise, very smooth indeed) than with 622 X 54s at 20 psi. Some years ago I rode a 451 bsd Dahon fixed gear with ~340 mm tires at 30 psi over the same expansion cracks. I never worried about it, particularly, and the tires were pretty beefy and not gossamer RH’s, but you did feel the bump more than with taller tires.
