Do you guys find that bikes are worth more sold in pairs? For example, I often see matching his and hers bikes for sale on C.L.? Or what about two identical men's bikes? I mentioned above that I picked up a couple mtn bikes, they look exactly the same. I don't really need two of the same bikes so I was thinking of selling one as is, as needing work, for $20-$30 in order to help with the cost of refurbishing the other, but for some reason I'm a little hesitant to break up the pair. Neither one of the bikes will make a lot of money, but would their value increase if I get them both in good condition and sell them together?
