Perhaps a different approach might work better. The problem faced by
the average criminal is to steal the bicycle without destroying it.
That's easy when the lock is an independently removable accessory.
However, suppose the lock were designed and built as an integral part
of the bicycle frame. Cutting the lock would destroy the value of the
bicycle making the theft much less profitable.

I recall talking to Steve from S&S Torque Couplers. He would sometimes
disassemble the frame then re-assemble it around a fixed object. Without
the proper tool, it's difficult to separate the frame.
