I like this Tyrell prototype as well; not sure I agree with the "Looks better than a birdy" comment, especially the new monocoque designs, but also the older design as well. As a Birdy owner, I do appreciate the chain length maintained in the fold and the rollers at the bottom of the folded package, but that cutout in the NDS "seatstay" makes me wonder if the crank positioning while folding isn't just as particular as the Birdy.

I fail to see much difference at all between this Tyrell being inspired by a Birdy and the Dahon Curl being inspired by a Brompton, aside from the lack of critical poutrage.
