For a long time I had been trying to figure out how to mount my kryptonite cable lock bracket onto my bike. My bike frame is small and the lock and bracket didn't fit when mounted on any of the frame's tubes. The cable lock needed more clearance than my frame allowed. But I didn't want to give up on the bracket since it really is a good design aside from the fact it doesn't fit.

What I finally ended up doing was to mount a piece of wood (painted black to match the frame) on to my rear rack and then mount the bracket onto the piece of wood. I sawed off the the part of the bracket that would normally attach to the frame and used two screws to mount the sawed end of the bracket flush to the piece of wood. The piece of wood attached to the rack using two j-bolts (see first picture). I also had room to mount a rear flashing light. It took more work and time than I had thought.
