Black is my least favorite color, but OTOH, the Ridley bikes on this page look like they might be good deals - possibly too good to pass up. No idea which would be more desirable to thieves between the black and the white - I guess I could cover up the "Ridley" logo but then I'd probably have a harder time reselling the bike later. I find both colors bland and would probably put a bunch of stickers (reflective and regular alike) to add more color.

I like the colors of the QBP bikes (Surly, Salsa, All City) but it's harder to find good deals on those.
