Build a hypothetical post-apocalypse bicycle

Do you want near indestructability, or the possibility for constant repair, and maintainance?

Interesting question... on one hand do you opt for a tank, and get the industructability? Or do you opt for a Citroen 2CV and have the car that famously any farmer could fix?

I think we're basically shooting for a bicycle equivalent of a 2CV. It won't be pretty, but it would do the job and anyone would be able to fix it using scavenged parts and basic tools.

Washing machine bearings are a great idea, especially if that's a fairly standard part. They'd keep well in the unused machines too.
