I've got a question about the old Murray cruisers, which is a copycat design of the old classic schwinn cruiser. First of all, I can purchase one at in rideable condition at my second-hand bike shop for $15.
What I would like to be able to do is use it as a general beater bike, and maybe commute a couple of miles to work. Ultimately I would like to convert it to a fixed-gear. Is it possible to convert this type of old bike to fixed? Would this bike be good for that, or should I hold out for a real schwinn? I would like to be able to ride light-duty off-road fixed also. thanks
