Yesterday I could test ride the Birdy of a friend. It was a Birdy Red with the new frame. OMG, what a difference to my Dahon Mu Sport. The Mu excels in practically all aspects. I was quite surprised because I expected much more from a Birdy. But the Birdy wheelbase is too short. It comfortably rides from A to B, no question. But Jumping curbs and agressively weaving through traffic ist not its task. The whole geometry does not allow for sportier ride. Plus 18" small wheels and smallish tires (but upgradeable to Big Apples). The suspension works, but makes the ride imprecise. No hands-free riding. Unfortunalely also the long handlepost is not as stiff as the one on the Dahon (its weakest part). Also parts selection is quite mediocre in comparison to the Dahon (with Nexus hub). Also folding, rolling and overall handling seems to bee different worlds. All together it still costs twice as much as the Dahon. I really don't understand why it gets so high reviews here. What am I missing?
