Packing for transit of almost any bike to fit in 62 linear inches is a major pain:

Here's what it takes to get the 20" Airnimal Rhino into a case:




TSA will then try to take it out, rip your case apart and then not wrap things up or be able to get it all in just right so they wont be able to close the case tightly when they are done.

The Brompton is a lot better for them as it just lifts out as one item.

As a next project, that Ibis Tranny frame sure does look nice - just for in car transport though.

I did once get my full 26" MTB to NZ free - by having one bag with a stripped frame and the wheels and bits in another - to be honest that was not any more work than packing the Rhino.
