Sweet mother of jesus! That's quite a collection! Very nice! I would do crazy stuff for any of those bikes! What is was curious about:

How big is the quality (ride, flex, folding, comfort, speed) difference between each bike? Big diff between Dahon and BF? I am particularly interested between the difference in the two fridays as i am considering both for a (future!) purchase. Also, how come you didn't go for a Pocket Rocket pro?

Do you think the BF's could last indefinately with some care? Maybe even decades?

The pro is prob. the bike i most want but i am a little worried that i won't be suitable for somewhat loaded touring (as BF site suggest) and as i can only spend that kind off loot once i would really like to have a durable bike that can pretty much do it all.

Thanks!
