Turned out to be a way-fun bike. Before the BF "upgrade", I had uploaded pix of the disassembled bike fitting into a legal check-in size suitcase, but it was more than just a few minutes of disassembly.
Interesting! How did it ride with two speeds? Was your principal reason for doing so to cut weight, or for utility? Rebuilt an 820 Antelope with an X-RF5 a couple years back and was playing with doing a similar modification this time. Well, using anything built by Sturmey-Archer, anyway. It just wouldn't be proper otherwise.
Edit:
Oh, so I test-rode a Brompton this weekend. Yeah, they're really nice.
