Given the ever changing limits on batteries (especially LIoN) on airplanes, I'd think an ebike only strategy could be iffy for Brompton.

[MENTION=72029]diode[/MENTION] "The new breed of cyclist in the UK seems to use cycling as a means to get a "work out" without having to go to the gym, so I'd imagine going for an electric bike would be counter productive." Studies suggest that you get a similar workout Quikbytes:Same Great Workout, Just Faster and More Fun (for example). Speaking from personal experience with a Stromer ST-1, I'd say they are spot on. Mostly the difference is how fast I get where I'm going (my physical effort is more or less constant); in addition it greatly increases my days ridden (due to the time savings). In fact, I got rid of my car, I do all of my commuting by bike. Currently, I use a Dahon when traveling but planning to upgrade to something better (downtube mini, Brompton, or ?).
