The Bike Cuff is designed to be used with another lock. Like "The Club" for cars, the Bike Cuff is a theft deterrent. It takes care of securing the front wheel and the frame, and in the process immobilizes steering at a 40 45 degree angle. The tight adjustable fit was inspired by handcuffs. This reduces space for insertion of pry tools and cable cutters.
This was a term project for IEOR 170 at the University of California Berkeley.
I am aware of the Master Lock Street Cuff. The Bike Cuff was designed with this in mind and has several advantages of the Street Cuff and AXA Lock widely used in Europe. The primary problem with the Street Cuff is that it the two halves are joined by a metal chain. This lock has been defeated by simply cutting the chain. These slides could not be discussed within the 10 minute presentation.
