Here they are all geared up:

They weighed about 80 lbs each fully loaded. We rode them for a total of 40 miles over a 1600' pass, camping near the summit for the week.
I managed to snap my rack in half in a ditch, but it was easily repaired with some paracord:
Held up all week, too! Other than a flat tire, we really didn't have many problems out of them. I'll post the full story once my photos come in from the lab.
I actually like the tyres more that the U frame folder came with. Out of character with the bike I'm sure but they look like comfy thick profile BMX tyres.
They were, but the forks were just too narrow for them to fit without rubbing. I gave them to a neighbourhood kid for his BMX.
