Hi -
I am new to the folding bike scene, and I have a little bit of a conundrum. Where I currently live has lots of access to pretty easy trails, through fields and such. I would like a folding bike that can take those trails, so I was considering the Montague DX. I also like the full-sized wheels on that. However, I am moving to the city in three months and will want the bike to commute and for the subway. So I am also considering a Dahon D7 or maybe a Dahon Espresso. I am not sure what the difference is between them besides wheel size (I cannot find a good review of the Espresso). Finally, I am considering a Downtube ISFX. Could I please get some feedback on these bikes, and whether the non-full-sized bikes can take an easy trail? Cheers!
