I suggest reaching out to Mobic and Bfold. See how they compare and what models they can actually get you. Then try Max Yeh and see what he can do. The shipping and custom duties could be problematic. The person I bought my bike from had ordered it from Bfold. He bought a standard 9 speed but had it modified to a mtb 10 speed and changed the stem to the one used on a GT and had Jackblack tires installed. Not sure why he didn't just get a GT.
I checked out St. Kildas in Australia and they have really good sale prices but do not ship to the US.
The Birdy seems popular everywhere else but in the US. Which I don't get. Maybe it's the price point.
I check out the Global Birdy Community on Facebook and everyone seems to be very excited about the new R20 11spd. So the older 11spds are going on sale.
