Hello, I'm new to the cabe but have been playing with vintage bikes since retirement a few years back. Mostly Schwinn cantilevers but I picked up this '81 Murray cruiser in good shape overall for a very modest price mostly for the rear hub, which I think is somewhat unusual on a 26" "Value Priced" American made bicycle. The rear coaster brake hub is a Sachs 2 speed automatic model A2110, not a kickback but a true automatic. The fellow I got the bike from indicated that the hub is original to the bike as purchased at Pat's Schwinn in Mesa AZ. My question to this learned group is whether there is any reason to leave this rather mediocre bike intact (as being rare or valuable) or use the hub in a '67 Schwinn Racer resto-mod I have underway. Thanks in advance for any information or opinions you may care to share.
