This lock is a cable lock, which is known for its flexibility and ease of use but may offer less security compared to U-locks or chain locks.
Security Level:
Bike locks are often rated by security levels, such as bronze, silver, gold, or diamond, with diamond offering the highest security against angle grinders. The packaging in the image mentions “Security L,” but the specific security rating system (if any) is unclear.
Material:
While not explicitly stated on the packaging, cable locks typically consist of a steel cable covered in a protective plastic coating. Some high-security locks use hardened steel.
