I have gone back and forth a couple times with a Arc Rear Rack (ie not the aluminum) on my Dahon Speed D7 and I am curious if you guys run a rear rack on your folder and why.

I don't commute on my folder and only occasionally fold. I haven't found a use for the rack and if anything it hinders (not greatly) its ability to fold. I haven't bought panniers either but given how the dahon folds, I don't know if I would buy two. I basically use the bike for mixed travel or when there is no bike rack. My only reservation for ditching it entirely is if I need it.

So do you guys use your racks on your folders, and if so why?
