I'm starting to re-think my original post. Traveling with a full size folder (even if I didn’t have to pay the oversize fare) would not be practical because of what I need to bring with me. I’m limited to 2 50# checked bags and one carry on. I typically travel with 3 bags. A backpack (as my carry on) and 2 checked bags.
1) In the small - about carry on size – bag - I'm an EE - so in this bag I carry the tools I need for the job - meters, a few hand tools, com cables for different devices, steel toe boots (most sites I go to are industrial), and drawings for the job. About 38 pounds
2) In a large bag - Clothes, running shoes, workout gear, protein powder (it's notable, because it's heavy), books, toiletries etc. about 45 pounds.
I figure, if I get past the ego issue of riding a small wheel bike, I can fit it in with what I carry now (but having 2 large bags), with a bit of redistribution, and stream lining what I carry on a trip.
Realistically, a full size bike would not work – I would be pushing size limits from the start – plus the hotels I stay in may not appreciate me wheeling a full size bike to and from my room – so I will need it to fold quickly.
The bike I will need would have to be similar to my Specialized Tri-cross. I use this as my commuter when I’m in town. I have done a century on it, ridden single track, mount studs on it in the winter – is a do all bike that performs well.
I have looked at the Dahon and Friday sites a bit – any specific suggestions?
