>>1584652some BSOs were of very dubious quality to begin with and then they might have seen decades of commuter use and abuse so while the durability isn't always a big concern, with the performance and comfort also being shitty i wouldn't want to ride a really shitty old bike that's for sure, especially if i didn't wrench on it myself and then there's a bit of a learning curve and investment in tools to work on an older bike
