Sold Secure Gold bike locks: The List

At the bottom of this page you’ll find a long list of Sold Secure Gold bike locks. U-locks, chains and folding locks, they’re all here (updated September 2020)!

But first, just in case you don’t know who Sold Secure are or what they do…

Sold Secure is an independent, non-profit organisation based in the UK. They test and certify locks to make it easier to compare the security levels between different types and brands.

The Sold Secure Lab

No lock gets out of here alive: the Sold Secure workshop!

Manufacturers can submit their locks to Sold Secure who will try to defeat them using a wide range of different tools and techniques.

They then classify each lock according to the amount of time they took to defeat it, with four available classifications: BronzeSilver, Gold and (new for 2020!) Diamond...

Sold Secure now rate locks from Bronze to Diamond

In the past, Sold Secure stated that a Bronze rating was for locks that could withstand “a minute with basic tools”, a Silver rating was for locks that could resist for “three minutes with a wider selection of tools” and Gold was for locks that lasted “five minutes with a sophisticated array of tools”.

However, they have since removed this quite specific classification from their website, preferring this much vaguer guidance:

  • Diamond rated locks “provide the highest level of security ... aimed at very high value bicycles and e-bikes.”
  • Gold rated locks “offer the next highest level of security, aimed at mid-to-high value bicycles.”
  • Silver rated locks “offer a compromise between security and cost.”
  • Bronze rated locks “typically offer defense against the opportunist thief.”

While there has been some criticism of their testing techniques and the resulting classifications, there are number of very good reasons that we should use their ratings when choosing the best lock for our bikes:

  1. Their tools and methods are standardized. So you can compare the ratings of different locks with confidence
  2. They use inside information from the police and insurers to keep their tools and methods up to date
  3. Many insurance policies specify that you must use a Sold Secure rated lock
  4. Of all the independent testers, they classify by far the widest range of locks
  5. The purpose of the organisation is to test locks. They know what they’re doing.

All this means that the Sold Secure rating system is the easiest and most accurate way to judge the security of a bike lock.

But how do you know which rating you need? It depends on your own risk level. And this can be difficult to judge. However, I recommend you 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:

Sold Secure Gold and Diamond
Sold Secure Silver

If two or more of your answers put you in the “High Risk” column, you should buy either a Sold Secure Gold or Diamond rated lock. Whereas if two or more of your answers put you in “Lower Risk” column you could possibly get away with a Sold Secure Silver lock.

I don’t recommend Bronze rated locks at all because they just don't provide enough protection.

Gold vs Diamond

So if you're high risk, which should it be: Gold or Diamond? Well the truth is: it's a bit complicated at the moment!

Locks can only be rated when they're submitted for testing (once every year). Since the Diamond rating is new, there's loads of locks that are currently rated Gold, but will definitely be bumped up to Diamond when they're tested again.

This means the current picture is slightly distorted. We can't assume that locks on the Diamond list are more secure than all the locks on the Gold list. Because they're not.

The Kryptonite New York Fahgettaboudit is still rated Gold for example, but it's more secure than almost every other lock on the Diamond list!

All we can be say at the moment is that the locks on the Diamond list are very secure! So look at both lists. As I mention below the best way to determine which locks are more secure is to look at the "shackle thickness" column. Generally, thicker = more secure.

If you have any doubts about ratings and security levels, leave a comment below and I'll get back to you very quickly.  

Finding Gold rated Bike Locks

So how can you find locks with a Sold Secure Gold rating?

You can find a complete list of Sold Secure locks (and other security items) on their website. But it’s not very user friendly.

So I provide a list of the best Sold Secure Gold bike locks here. If you click on the names of the locks in the table, you’ll be taken to Amazon or other websites, where you can further compare prices and reviews. Some of these are affiliate links.

At this point you may have a couple of questions:

1. Are all Sold Secure Gold locks as secure as each other?

No, not at all. The easiest way to tell the difference is to look at the “Thickness” column in the table above. Generally, the thicker the lock, the more secure it will be.

2. This list is missing some very secure locks. Why?

For a lock to be rated by Sold Secure, it must be submitted by the manufacturer. And there’s plenty of really good locks that are either never submitted or have not been submitted yet. But that doesn’t mean they’re not Sold Secure “standard”.

Off the top of my head:

  • OnGuard Brute Mini U-lock
  • Kryptonite New York Legend Chain
  • OnGuard Beast Chain

These are all Sold Secure Gold “standard” bike locks that don’t have a Sold Secure Gold rating.

If you want to see which locks would most likely be granted a Gold rating if they were submitted to Sold Secure, you can use the manufacturers own ratings on the u-lock comparison and chain lock comparison pages:

If a lock without Sold Secure certification has the same manufacturer rating as a lock with certification, it's most likely Sold Secure "standard".

3. Aren't the Abus Ultimate 420 locks rated Sold Secure Silver?!

Yes they were. But they seem to have been re-tested and now they have a Gold rating! You can check the Sold Secure or Abus websites to be sure!

However since the locks available on Amazon (and elsewhere) tend be the ones with the Silver rating, I've removed the links until the Gold versions are more widely available.

Also, be careful: I have seen several locks marked as Sold Secure Gold on Amazon and other websites that are in fact not. If in doubt check the Sold Secure website itself.

4. Aren't the Kryptonite Kryptolok u-locks rated Sold Secure Silver?

At the moment Kryptonite make two versions of the Kryptolok. The Series 2 is the original and is rated Sold Secure Silver. The New-U is well, new(!) and is Sold Secure Gold.

Visually the locks are almost identical. But there are subtle structural differences that account for the different ratings by Sold Secure.

The Gold rated Kryptolok New-U

The Series 2 features the famous "bent foot" shackle which makes it easier to fasten the lock when you're securing your bike. But the bent foot side of the shackle isn't locked into the cross bar with a dead bolt.

The "bent foot" shackle of the Series 2 omly locks on one side

This makes the lock more susceptible to twisting and leverage attacks which can pop the bent foot out of the crossbar and defeat the lock.

Whereas the New-U shackle locks into the cross bar on both sides making it more resistant to these type of attacks (which are one of the most common methods of defeating decent u-locks).

So the bump up in ranking makes sense so far.

However, the Series 2 seems to be made from better steel (top of the range "Max Performance") than the New-U (standard "Performance"). Not only that, the Series 2 shackle is thicker (13 mm) than the New-U (12.7 mm)!

So bearing all this in mind: the Silver rated Series 2 will be more resistant to bolt cutter attacks than the Gold rated New-U!

Presumably Kryptonite wanted to keep costs down and worked out they could still get up to that Gold rating with slightly inferior steel and shackle diameters. Which is fair enough!

In my mind they both remain very good mid security locks. But the New-U is not a high security option.
