You're welcome. I remember seeing that montague some time ago when i was looking for something similar to what you are looking for - a folding travel bike.

To complete the kit, I would have a rectangular travel bag custom made, from tough nylon or some other material, then i'd line it with cardboard. at the other end of the flight, after putting the bike together, i can just throw away the cardboard lining and keep the custom bag rolled up and lashed to the frame or something. I'd also design the bag to open completely so that it would double it's function as a ground tarp or a sleeping pad.

I have something like this, but for a normal 26" mountain bike - a large cordura nylon bike bag that i can use as a sleeping pad. a bit cumbersome though because it is such a large bag.
