For those researching minivelos, I stumbled into this Thai thread with tons of pics of minivelos.

Many I've never heard of, clearly most were not for the US market but cool to check out anyways.
Oddly I don't see many minivelos rolling around Bangkok but I think they are ideal for such a congested place with small apartments..
I do see a lot of folding bikes, MTBs, roadies, and fixies though.
