Folding Bike for Sale

I made an impulse purchase for a Dahon Shadow single speed folding bike, thinking it would be convenient for reducing the walks on each end of my metra stops. Turns out, walking works out just fine, and the folding bike is therefore not needed. It is BRAND new, has only been used for 3 days, but was purchased before well before I began using it, so the return period has passed. I paid $400 for it. Make me a fair offer and we can take it from there.
