Looks nicely thought out. I remember when Bicycling! first ran an article on the Bike Friday with its trailer/suitcase for self-contained travel, including to/from the airport. It got me interested in folding bikes and I bought one of theirs about a year later. It hasn't been getting quite as much use lately as when I was going on lots of business trips, but I'm glad to have it available whenever I travel - and the trailer/suitcase has come in handy on a number of occasions.
