However, most (all?) of these bikes are older and some modern technology that greatly increases durability may not have been used on the bike when manufactured. Specifically, a rear wheel with a 'freehub' (freewheel mechanism built into the rear hub) rather than the older and less robust separate 'freewheel' mechanism. If this is the case for the bike you're looking at, consider upgrading the rear wheel to a freehub type hub for durability.
