I purchased a Montgue ‘Paratrooper’ model last spring ‘07’ and have been very happy with it. Was my first bicycle in over 25 years. I haven’t dropped it out of an airplane so I can’t tell you how well it flies.
It may be heavy – I don’t have anything to compare it to.
I’ve used almost daily for 10-15 mile sessions. Used on the road, mountain bike, and rail trails. My favorite rail-trail is just a flat single track with very few improvements from the abandoned roadbed.
I fold to carry in the car as needed. Very quick to dis/assemble with no tools.
Replaced the stock pedals since the ones provided were junk. I haven’t had any breakage or failing parts. Out of the box it rode ‘OK’. A trip to LBS for fine tuning improved the ride.
