I got a chance to try this out in my recent trip to Mallorca. It worked great! The only real issue is to keep the cab drivers from using the straps to pick up the whole box!

BTW, the fold out "outriggers" need to be as long as possible to keep the wheels on the box. This appears to be a fatal flaw in the original design which may be why it was abandoned.

Th wheels were made to be adaptable to 8-12" wide bike boxes. The box I used which only required removing the front wheel and the stem was a standard 10" wide box that REI uses to ship bikes. I found it quite snug width wise as the front tire (wrapped in cardboard) would only fit amidships in the box.

BTW, I have attached some photos of the packed bike in the box to show the lack of side clearance in a 10" wide box. I don't know if any of you have any better suggestions on how to pack but this is the best that I could come up with. The other issue that needs work is that the box is about 4-5" too long so the bike "package" will shift within the box which damages and wears on the inside of the box which is bad if you intend to reuse the box.
