Sold Secure Diamond Bike Locks: The List

Sold Secure have added a fourth level to their bicycle lock security ratings: Sold Secure Diamond! And it now becomes the highest security rating for bike locks. From their 2020 catalogue:

  1. Diamond locks: "provide the highest level of security ... aimed at very high value bicycles and e-bikes."
  2. Gold locks: "offer the next highest level of security, aimed at mid-to-high value bicycles."
  3. Silver locks: "offer a compromise between security and cost."
  4. Bronze locks: "typically offer defence against the opportunist thief."

At the bottom of this page you'll find a full list of all the Sold Secure Diamond locks currently available (updated June 2022).

Sold Secure bike lock ratings

Sold Secure rate the security of bike locks from Bronze to Diamond

Why introduce a Sold Secure Diamond range?

It seems easier than ever for a lock to achieve a Gold rating, and as a consequence there are more and more Sold Secure Gold locks every year. Which dilutes the value and confuses the customers.

Certainly there is wide range of different security levels included in the Sold Secure Gold rating.

For example the 16 mm Kryptonite New York Standard and the 12.7 mm Kryptonite Kryptolok are very different locks, offering very different levels of protection. But they're both rated Sold Secure Gold!

So a new, higher level (Diamond) is definitely a step in the right direction.

Do you need a Sold Secure Diamond bike lock?

This will depend on your risk level. And the easiest way to work out your risk level is to answer the 3 quick questions in the quiz below...

The quiz above will recommend either a Sold Secure Diamond or Gold bike lock if your answers place you in a higher risk group. Or a Sold Secure Silver bike lock if your circumstances are lower risk.

It won't recommend Sold Secure Bronze bike locks because they're not secure enough for any circumstances!

Sold Secure Diamond vs Gold

Bear in mind that locks can't be rated Diamond until they're submitted for testing. So for a while, the picture will be confusing as locks that should be Diamond remain Gold!

Also, you may buy a lock that's now rated Diamond but is still labelled as Gold on the packaging when you receive it, as it will take some time for new (Diamond) stock to get into the market.

Yes, I know it's confusing and it will remain so for some time! If you have any doubts about the rating of any lock, leave a comment below and I'll get back to you as soon as possible!

June 2022 Update: It seems like the lock manufacturers are still submitting their locks for both Gold and Diamond accreditation. This could be because Sold Secure Gold is a more widely known rating.

Finding Diamond rated Bike Locks

You can search for all the Diamond rated bike locks on the Sold Secure website. But it's not very easy to compare different locks there.

So I've compiled a complete list of all the Sold Secure Diamond locks below. If you click on the names you'll go to Amazon or other websites where you can compare prices and reviews. Some of these are affiliate links.

The "Cans of Coke" column lists the approximate weight of each lock in cans of Coke! I think this will help you imagine how heavy the locks really are.
