Thanks Artkansas. I really didn't think anything beyond the interesting bikes when posted (didn't even bother to read the article in fact).
P.S. Why couldn't we have tandem taxis these days?
We can. Most pedicabs these days are toys though. Made to drag tourists around flat places. I'm guessing that the tandem taxi's were intended to actually cover a fair distance with some speed. Necessarily, though they would double your labor costs over a pedicab.
