Best Rated Bike Locks: Secure Your Ride

Whether it's the bike you commute on every day, the road bike you've spent years upgrading or the e-bike that replaces your car, choosing the right lock is about protecting something that's worth far more than its price tag.

With so many products claiming to be the best, it can be difficult to know which locks genuinely deserve their reputation. The highest-rated bike locks don't just perform well in one area. They earn trust through independent testing, expert reviews and real-world rider feedback.

What makes a bike lock one of the best rated?

A highly rated bike lock isn't simply one with hundreds of five-star reviews. It's one that consistently proves itself through independent testing, expert reviews and real-world use.

Before buying, look for evidence from several different sources:

Independent security certifications such as Sold Secure.
Customer reviews from riders who've used the lock over time.
Reviews from trusted cycling publications.
Independent testing by YouTubers and content creators.
A manufacturer with proven experience designing bicycle security.

When all of those point in the same direction, you can buy with far greater confidence.

Understanding bike lock security certifications

Independent certification is one of the best ways to compare bike locks because every product is tested against the same recognised standards. Rather than relying on manufacturer claims, you can see how a lock has performed under controlled attack conditions.

Different certification bodies use different testing methods, but they all have the same goal: helping riders identify products that offer a proven level of security.

Sold Secure

Sold Secure is one of the most recognised security certification schemes in the UK and is widely recommended by insurers, retailers and manufacturers.

Bike locks are tested against a range of attack methods before being awarded a certification level. For bicycles, the ratings are:

Diamond – The highest level of bicycle security, recommended for high-value bikes and e-bikes.
Gold – High security for many everyday bikes and commuting environments.
Silver – Suitable for lower-risk situations.
Bronze – Basic security for lower-value bikes or low-risk locations.

These ratings come under the Sold Secure Pedal Cycle (bicycle) category. However, there are also specific ratings for motorcycles, referred to as Sold Secure Powered Cycle. And in fact, some bicycle locks are strong enough to be awarded the Sold Secure Powered Cycle Diamond rating.

For riders investing in a premium bike, choosing a Sold Secure Powered Cycle Diamond lock provides confidence that it has passed demanding independent security testing.

ART Foundation

ART is a Dutch independent testing organisation recognised across Europe.

Instead of Gold or Diamond ratings, ART uses a star system. The more stars a lock receives, the greater its tested level of security.

Many insurers throughout Europe recognise ART certification, making it another useful benchmark when comparing products.

Varefakta

Varefakta is an independent Danish certification scheme that tests products against defined quality and security standards.

For riders in Scandinavia, it's another trusted way of identifying locks that have been independently assessed rather than relying solely on manufacturer claims.

Other recognised certifications

Depending on where you live, you may also come across organisations such as SBSC in Sweden or FG certification in the Netherlands. There's also FUB in France and ENRA in Europe.

While each organisation has its own testing procedures, they all serve the same purpose: providing independent evidence that a lock has met recognised security standards.

Why certification isn't the whole story

Independent testing is one of the most important things to look for when buying a bike lock, but it doesn't tell the whole story.

Every certification scheme has a highest rating. For example, many premium bicycle locks achieve Sold Secure Powered Cycle Diamond certification.

The challenge is that once a lock reaches that level, the certification doesn't distinguish between products that just meet the standard and those that significantly exceed it.

Two locks may both carry the same Diamond rating, yet perform very differently when faced with modern theft techniques.

This is one of the reasons anti-angle grinder locks have become increasingly popular. While several locks may achieve Sold Secure Diamond certification, products designed specifically to resist angle grinder attacks can offer significantly greater resistance to one of the most common theft methods used against premium bikes today.

That's why it's worth looking beyond the certification itself.

Independent attack tests

One of the best ways to compare two highly rated locks is to see how they perform in independent attack tests.

Unlike formal certification, these demonstrations often mimic real-world theft attempts, showing how different locks respond to common attack methods and highlighting the design features that make a difference.

For example, reviewers may test:

Angle grinder resistance
Bolt cropper resistance
Twist and leverage attacks
Lock-picking resistance
Anti-rotation features designed to prevent a thief completing a cut

These demonstrations don't replace independent certification, but they add valuable context when comparing products with similar security ratings.

A lock that takes longer to attack, wears down cutting discs more quickly or incorporates features that make follow-up attacks more difficult can offer a significant advantage in real-world conditions.

At Hiplok, our 1000 Series products were developed with modern theft methods in mind. Features such as anti-angle grinder materials and anti-rotation technology are designed to increase the time, effort and equipment needed to carry out a successful attack.

Customer bike lock reviews tell you what testing can't

Laboratory testing is essential, but it doesn't explain what it's like to live with a lock every day.

That's where customer reviews of bike locks become valuable.

Thousands of daily locking and unlocking cycles quickly reveal details that matter to riders, including:

Whether the lock is comfortable to carry.
How smoothly the key mechanism performs over time.
How well protective coatings prevent frame damage.
Whether the lock fits typical bike racks and street furniture.
How durable the finish remains through year-round riding.

These practical experiences help answer questions that formal testing isn't designed to cover.

The best products consistently perform well in both areas. They achieve recognised security ratings while also earning positive feedback from riders who use them every day.

Professional reviews

Alongside certification and attack tests, professional reviews provide another valuable source of information.

Trusted cycling publications such as BikeRadar, Cycling Weekly, road.cc and respected YouTube creators often review multiple locks side by side, making it easier to understand where one product excels over another.

These often include:

Ease of carrying.
Day-to-day usability.
Locking speed.
Frame compatibility.
Weather resistance.
Build quality.
Value for money.

When a lock performs well in independent certification, professional reviews and real-world attack tests, it's a strong indication that its reputation is well deserved.

Bringing it all together

By now, you've probably noticed a pattern.

The best rated bike locks rarely earn their reputation because of one feature or one glowing review. Instead, they're consistently backed by several forms of independent evidence.

When comparing two locks, look for products that perform well across all of the following:

Independent security certification, such as Sold Secure or ART.
Positive reviews from long-term owners.
Recommendations from trusted cycling publications.
Strong performance in independent attack tests.
A design that's practical enough to use every day.

A lock that scores highly in every area is much more likely to provide reliable, long-term protection than one that's only strong in a single category.

FAQs

What is the best rated bike lock?

The best rated bike lock is one that consistently performs well across independent security testing, customer reviews, professional reviews and real-world attack tests. Looking at all of these factors gives you a more complete picture than relying on star ratings alone. Hiplok's highest-rated bike locks include the D1000 and DX1000, which combine Sold Secure Powered Cycle Diamond certification with anti-angle grinder technology. They have also received consistently positive feedback from customers and independent reviewers.

Are Sold Secure Diamond bike locks worth it?

If you own a high-value bike or e-bike, a Sold Secure Powered Cycle Diamond lock offers the highest level of independently certified bike security. It's one of the strongest indicators that a lock has been tested against demanding attack methods.

Can customer reviews tell you how secure a bike lock is?

Customer reviews are excellent for understanding how a lock performs in everyday use, but they don't always reflect its security. Most riders won't experience a theft attempt, so independent certification and attack testing provide a better measure of theft resistance.

Are YouTube bike lock tests reliable?

Independent YouTube reviews and attack tests can be a valuable source of information, particularly when comparing two highly rated locks. While they shouldn't replace recognised certification schemes, they help demonstrate how different designs respond to realistic theft attempts.

Which type of bike lock is the most secure?

In general, high-security D locks offer the highest levels of protection, with many achieving Sold Secure Diamond certification. Anti-angle grinder D locks provide an additional layer of resistance against one of the most common modern theft methods, while products such as the Hiplok L1000 allow riders to add flexibility without compromising the anti-angle grinder protection of their 1000 Series setup.
