Sold Secure Diamond Bike Locks

Sold Secure had used a three-tier rating system to grade the security of different bicycle locks, until 2020, when the Sold Secure Diamond bike lock rating was introduced. 

At the time of  Sold Secure Diamond’s introduction, the Gold category had become overcrowded, and cyclists needed help understanding which of the many Gold-rated locks offered more security.

Additionally, as the e-bike market has rapidly expanded over recent years, the average price of a bike on our streets has risen, and the tools thieves are now using to steal bikes have advanced. 

So, Sold Secure introduced the Diamond rating to clarify confusion among cyclists and highlight which locks are suitable for the highest-value bikes and e-bikes.
