Thanks for sharing your expertise, all! Sounds like my bike is low value to bike thieves which is good news to me! Good advice from someone on the bike lock thread: why not get a decent lock that can be used on an upgraded bike if/when I get one? We've taken them out for a couple of 10-12 mile rides and I dig it, and my husband is kinda psyched about dusting off his old racing bike too! So maybe there will be an upgrade in my future, but this one is good for now. Here are some
photos of my new old bike.
