I just realized that the last three bikes I've bought are black. I probably have 12-15 other black bikes in my "collection" as well. These three are a 1967 Sear three speed , a "the Realm" cruiser with a springer, and a 21 speed Ancheer (?). Actually ,I buy pretty much any color, except pink.
I like bikes of every colour, but i'm particularly partial to red, green...and black. I have a lot of yellow bikes, but that's just how the retired industrial bike frames come from the factory. Aside from that, most of my bikes have been black...
