SFMoMA: San Francisco Museum of Modern Art. MoMA itself is in Midtown Manhattan but has Rockefeller roots (I think David Rockefeller, former CEO of Chase Bank, started it, but I could be mistaken).

There would have to be a call to the curator of industrial design. I'm not sure they do bikes at all, but mountain biking basically started in California (I'm thinking all the action around North Bay that quickly spread all over the place.) It could be of interest, but I'm not really sure.

I don't know anyone there, but six degrees of separation likely exist.

Best of luck with this. I think it's a great idea to write up what you have and send the bike off to someone or someplace that will enjoy it.
