You said that you can upgrade the Birdy, is it possible to install an Alfine, nuvinci or rohloff hub without modifying the frame or increasing wheel size to 20?
After you rode the bike for 18 + miles, did you take the public transportation at all?
I was looking at the Brompton but never tested it at Bfold. I like how unique the Brompton folds and how small it is after folding. However, ever since I checked out the Birdy, Brompton became my second choice. I can't really compare the two since I've never rode the Brompton.
I've read a lot of sites regarding the Birdy. In Taiwan and Hong Kong, you can almost put any components in the birdy. The problem is that it is very hard to get hold of them. I have friends that lives in Hong Kong so I might have to bother them to order for me and send them here in the US. Peter should be able to answer your questions regarding the upgrades.
Check out the Taiwanese forums
Google ???? - Mobile01. It has lots of upgrade info on the birdy. You can use google translate or using Chrome to read it...but it might give you a headache. I mostly look at all the pictures they posted on their upgrade bikes.
