Since each manufacturer uses their own scale to rate the security of their locks, it is often difficult for consumers to make comparisons between locks made by different manufacturers. A&Js' security rating is a guideline for the purpose of providing consumers with a consistent way to compare bike locks of a similar grade between various manufacturers, for more in-depth information about ratings please refer to the manufacturers rating system:
Ultimate Defense Locks - a rating of 6 out 6: Ultimate Defense Locks offer the ultimate protection and are appropriate for high-crime areas and college campuses where theft is a real threat. Ultimate Defense locks are typically available with a manufacturer supplied anti-theft protection award, that will refund you up to a certain dollar amount if you bicycle is stolen due to lock failure. *Abus does not offer manufacturer supplied anti-theft protection
Strong Defense Locks - a rating of 4-5 out of 6: Strong Defense Locks offer strong protection against possible theft for protection in areas with some crime risk and college campuses. Many of these locks are also available with a manufacturer supplied anti-theft protection award, that will refund you up to a certain dollar amount if you bicycle is stolen due to lock failure. *Abus does not offer manufacturer supplied anti-theft protection
