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:
- Diamond locks: "provide the highest level of security ... aimed at very high value bicycles and e-bikes."
- Gold locks: "offer the next highest level of security, aimed at mid-to-high value bicycles."
- Silver locks: "offer a compromise between security and cost."
- 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 November 2020).
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.
Which Sold Secure Rating do you need?
This will depend on your risk level. And the easiest way to work out your risk level is to answer the questions in the table below...
Questions | High Risk | Lower Risk |
|---|---|---|
Where do you live? | Big town, city or university campus | Small town or village |
Does your bike attract second looks? | Yes | No |
How long do you leave your bike unattended? | More than 1 hour | Less than 1 hour |
Cell | Cell | Cell |
Your lock should be: |  |  |
If all three of your answers are in the "High Risk" column, then you should probably choose a Sold Secure Diamond lock.
If two of your answers are in the "High Risk" column, then you can probably get away with a Sold Secure Gold lock.
Whereas if two or more of your answers are in the "Lower Risk" column, then you may be OK with a Sold Secure Silver lock.
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!
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.
