Not C&V, but 3-speed content: When Spin retired their dockless bikes in the South Florida region, I asked them for some my Bike Share Museum. They virtually handed me the keys to the warehouse.
Over the course of three months, I was able to donate 500 bulletproof 3-speeds between charities, community members, the county's bike program, and the non-profit I work for (who got them to Freeport to aid the hurricane relief).
Technically, there's still 38 rough ones to sort out, but COVID-19 has put the brakes on the project for now.
Got to keep two brand new ones for preservation too, plus one for my office (which is getting converted into a pedelec at the moment):
