I just took my Troll to the big island of Hawaii. It was great, I was mostly on roads but had a few dirt/sandy and lava rock trails as well.

I boxed it up and it was easy to get back and forth from the airports. That's exactly what I intended to do with this bike- take it around the world. I'm still considering cutting the frame in half and installing the S&S couplers so it will fit in a suitcase, that would make it even easier. I took a Dahon folding bike for my g/f that fits in a Samsonite and that was really easy too.

Trolls fly just fine!
