Where did the concept for the modern U-lock originate in 1971?

Answer

Massachusetts Institute of Technology

The foundational design for the modern U-lock was conceived by a small group of junior students at the Massachusetts Institute of Technology in 1971. Driven by the personal frustration of having a bicycle stolen, these individuals aimed to create a more effective defensive mechanism than the simple chains and padlocks that were available at the time. They developed a prototype featuring a hardened shackle specifically engineered to withstand the tools commonly used by thieves, which successfully established a new industry standard for bicycle security.
