Sold Secure Diamond Bike Locks: The List

Last Updated on January 12, 2024 11 Comments

In 2020, Sold Secure added a fourth level to their lock security ratings: Sold Secure Diamond! And this became their highest security rating for bike and motorcycle locks. From their website:

  1. Diamond rated locks offer “the highest level of security” (tests include angle grinders)
  2. Gold rated locks offer “a high level of resistance against a dedicated thief”
  3. Silver rated locks offer “a compromise between security and cost”
  4. Bronze rated locks offer “defense 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 January 2024).

Sold Secure bike lock ratings

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

Why introduce a Sold Secure Diamond range?

As bikes (especially ebikes) become more expensive, and thieves use new tools and techniques, there is obvious need for more secure locks.

But adding more secure locks to the Gold rating only dilutes its value (by adding too much variety). So a new Diamond rating, which is aimed at really high value bikes and includes angle grinder attacks, makes perfect sense.

However, the new rating system is complicated by a further distinction between Pedal Cycles (bicycles) and Powered Cycles (ebikes and motorcycles), across the Gold and Diamond ratings.

So in fact there are 5 different security levels across 6 different ratings:

  1. Powered Cycle Diamond
  2. Powered Cycle Gold & Pedal Cycle Diamond
  3. Pedal Cycle Gold
  4. Pedal Cycle Silver
  5. Pedal Cycle Bronze

The idea behind this distinction is that there are some locks more suitable for bicycles and some locks that are more suitable for motorbikes (and ebikes). For example, disc locks only really work on motorcycles.

However, since most locks will work with both bicycles and motorbikes, manufacturers tend to submit their locks to be tested for both, and we end up with locks that have several ratings (more on this below).

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 Pedal Cycle Diamond vs Powered Cycle Gold

It’s important to note that Pedal Cycle Diamond and Powered Cycle Gold are essentially the same rating, as they use exactly the same testing criteria. So you will find that many of the locks in the Pedal Diamond list below, are also on the Powered Gold list.

Likewise, it’s also worth noting that Powered Cycle Diamond is more secure than Pedal Cycle Diamond. It is reserved for locks with high levels of angle grinder resistance (see more below).

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.

The Litelok X3 and the Hiplok D1000 provide the most resistance to angle grinders. The Litelok X1 offers slightly less resistance, but it's lighter, cheaper, and it's the only one that comes with a frame mount.

About the author 

Carl Ellis

I've had bikes stolen in London, New York and Barcelona. Yep, I was a serial, international, bike theft victim. In 2015 I decided to stop the rot. And not a single bike's been stolen since! Brakes, yes. Bells, yes. But they're another story. Everything I learn, I document on this website. More about my story. Contact me. LinkedIn.

  • Hey Carl, in the new Sold Secure catalogue the Seatylock Mason has been Diamond awarded. Makeing it by far the lightest of its kind – it was already the lightest in the Gold section before. So I guess it shall also have its place in the best lightweight lock section. I wish the 180mm version has the great Click n’ Ride system that Hiplok has to carry the lock on your trousers (I even carried the Hiplok DX on my swim wear ^^).
    Best regards Thomas

  • OK you have found a way to stop your bike from getting stolen. In impressed I have st least 4 bikes stolen at the time living in NY it has made me sic anyway some one told me about gallium can be bought on amazon destroys aluminum..How have you avoided this situation. I’m putting together another bike vintage specialized and I’m not ready to loose this to a thief.
    How can my story end like yours?

    • Hi Stefan

      Thanks for your comment.

      Unfortunately the Sold Secure rating system has become ridiculously complicated.

      As well as Bicycle Gold and Bicycle Diamond, there is now Motorcycle Gold and Motorcycle Diamond.

      And each lock is often rated under both the Bicycle and Motorcycle umbrellas.

      So the Hiplok DX is Bicycle Diamond and Motorcycle Gold.

      If you look in the Gold and Diamond pages on this website, you’ll see I’ve divided them up this way and the Hiplok DX is listed correctly.

      Thanks!

      Carl

  • Hi, this is a great list. I see you haven’t included any of the Pewag products (also rated SS Gold) – any thoughts on these?

  • How come something like the Yale one is diamond rated and only like 30-40$? Is it really safe like other diamond ones and better than all the gold ones?

    • Hi Benny,

      Yes, it will very likely be more secure than the more expensive Gold rated locks. It might not be as well made though, so make sure you clean and lubricate it regularly.

      Thanks!

  • Hi, I’m planning on using level 10 ABUS chain and an ABUS Granit series lock to secure a bike.
    My insurance company insist on Secure Gold Rated locks & chains, any idea if they comply?
