There should be some Small Brown Bike and This Bike Is A Pipe Bomb on there. And that Defiance, Ohio song called Bikes And Bridges. Lucero have a song called Bike Riders, but it's about motorbikes. How about the BMX Song by the Bouncing Souls?

I've got some lyrics for a song called U-Lock Justice, but I've since found RAMBO's song by the same name.
