5 Things to Consider Before Buying Bike Locks

1. Type of Locks


A Bicycle U-Lock

Also commonly known as D-locks, these are made from hardened steel in shapes of D or U.

Normally, the U locks are covered in vinyl or rubber to prevent corrosion and also helps to protect the paint of your bike.

  • Pros. Compared to other locks, U locks are one of the hardest to break, pick or drill, even with a strong bolt cutter.
  • Cons. Because they are mostly made out of steel, they’re pretty heavy to carry around.

The Abus Granit X-Plus 540 U Lock is represents the best value for money. If you’re looking for one that is small, yet very secure, consider the Kryptonite New York Fahgettaboudit U Lock

Chain Locks

A Secure Bike Chain Lock

Chain locks are made out of steel chains and they usually vary in length, weight and chain size.

Chain locks often come with a built-in lock using combination locks or keyed locks. One such example is the Kryptonite Keeper 785 chain lock.

  • Pros. Chain locks are also usually longer and can reach up to 6 feet, which means it can easily be wrapped around your bike. It can also endure tensional forces.
  • Cons. Depending on the quality, chain locks are can often be broken by thieves using torsional forces.

Cable Locks

A Cable Lock on a Bike Frame

Cable locks are made of braided and twisted wires. They’re typically coated with plastic or rubber so that they don’t scratch your bike frame.

  • Pros. Cable locks are the lightest of all bike locks, which means they’re easier to carry. They’re also flexible and don’t need too much effort to be wrapped around other objects.
  • Cons. Cheap cable locks can easily be cut using bolt coppers. Furthermore, most cable locks don’t have gold or silver sold secure rating and typically rated with bronze rating, which isn’t good.

Folding Locks

Abus Bike Folding Lock

Folding locks are made out of steel bars connected through rivets.

They have the most distinctive designs among all bike locks. If you’re all about aesthetics and new designs, you’ll love this.

  • Pros. Easy to carry around and can be kept compact in your bag. They also vary in length and sizes, so there will be various options for you pick from.
  • Cons. Folding locks are relatively still new to the market, which means it’s not as available unlike its counterparts.
PRO TIP : U locks offer the highest level of security among all as they’re typically thick and available in various sizes.

2. Security Rating

If you’re eyeing a specific bike lock, it’s important to know its security level.


This is to know if a certain bike lock is worth paying money for and if it’s durable enough to withstand the various techniques used by thieves to break them.

But as consumers, which ratings do you go to and who should you trust?

Abus vs Kryptonite Security Ratings

Manufacturers Rating

Most manufacturers use their own description about how their bike locks are at a certain level, which would probably leave you and I confused and totally puzzled because we have no idea about the real meaning behind it.

Sadly, most leading manufacturers use their own security ratings and only compare among their own bike locks, which make their ratings even more unreliable.

Sold Secure

Sold Secure is a reputable non-profit association that evaluates security products sold to the public and provide ratings. Bike locks are one of those products they evaluate among many others.

To have their products rated; manufacturers send their products to United Kingdom.

Sold Secure ratings are classified into 3 categories:

  • Gold. This is the highest rating. Any bike locks that have this rating means it offers maximum level of security. For example, the Abus Granit X-Plus 540 U Lock and Kryptonite Kryptolok Series 2 U Lock
  • Silver. Offers a medium level of security and gives off good enough resistance to determined thieves. For example, the Abus Ultra 410 Mini U Lock.
  • Bronze. This is the lowest rating by Sold Secure yet it provides sufficient security from opportunist thieves. Bike locks with this rating is mostly recommended for cyclists biking around normal risk environment.

By now, you’d probably be asking, what’s the difference between all the security ratings?

Sold Secure Rating Explained

Sold Secure is the most trusted ratings among all security products like bike locks.

Their ratings are far from biased. So most likely they’re going to tell the truth about certain products.

The scheme is tested by a group of professionals and performs it by doing old and modern theft procedures. You can verify the Sold Secure ratings of a bike lock from their online database.

3. Size

Bike locks also differ from thickness, length and weight.

If you want to secure your bike against an immovable object, then I’d recommend opting for a lock with lesser diameter (example: Kryptonite New York Fahgettaboudit) that is just enough to wrap around the bike frame.

But isn’t the bigger the better?

Well, not really.

Thieves can take advantage of the extra space available inside the bike lock by using a leverage bar. Also, the weight of the lock also matters since you’re basically going to carry this around wherever you ride.

4. Keyed vs Combination

Generally, bike locks can be categorized in 2 types:

  • Keyed locks
  • Combination locks

Keyed Locks

Circular vs Flat Bike Lock Keys

Key locks use circular/tubular shaped keys or flat keys. It aligns the spring loaded pins located inside the lock and opens once the right key is inserted.

Keyed locks are generally durable and hard to break. However, if you buy a cheap bike lock, there’s a high possibility that thieves will be able to pick it by just using a pin.

Combination Locks

Combination Bike Locks

Combination bike locks on the other hand uses multiple dial locks or single dial locks, which means it requires you to remember a series of numeral codes.

It’s convenient to use because you don’t have to worry about losing your keys unlike the keyed bike locks.

In spite of this, combination bike locks can still be cracked by any determined thief in around 40 minutes to 4 hours.

PRO TIP : Keyed bike locks are preferred and provides more security.

5. Reputable Brands

While there are hundreds of bike lock brands in the market today, some are always the go-to brands.

Kryptonite and Abus are the top 2 bike lock companies and they’ve both been around since the 70s. But which one is the best?

I’ll let you decide.


Abus is a prominent European brand founded in 1971.

They’re one of the first companies to offer bike locks and since then, they’ve been known for their reliability and good reputation.

Their locks are made in Ruhr Valley located in Germany which ensures that they’re using quality European steel. Abus also offers replacement keys in case you lost it. Each Abus bike locks come with a card where you’ll quote the code on it to them for keys replacement.

Kryptonite Locks

Kryptonite Locks has been around since 1970 and was founded in United States.

They are usually a little cheaper than Abus, which makes it a good candidate for those trying to save money.

Moreover, Kryptonite provides one of the best customer services. In case you lose your keys, they offer to give replacement keys for free so long as you’ve had your lock registered.

Additionally, they also offer their own anti-theft protection if your bike ever get stolen because of their locks.

One thing to note though. Kryptonite manufactures their bike locks in China/Taiwan as compared to Abus in Germany.

All in all, if you want to achieve reliability, value for money and excellent service, then Kryptonite it is.

Frequently Asked Questions

1. Which type of locks are the safest?

The best type of bike locks are definitely U locks, taking into consideration of all the pro and cons. You can see my list of U locks recommendations above.

U-locks offer the highest level of security among all as they’re typically thick and available in various sizes.

Because they’re made out of hard metal and rigid construction, U-locks are pretty challenging for bike thefts to cut or break.

2. Which U-lock thickness should I buy?

Go for U-locks with diameters ranging from 16 to 23 mm and above.

This way, even if the thieves use the biggest bolt cutter on the planet, they’d have a hard time doing so.

For U locks, it’s smarter to select the ones with thicker metals. An average-sized bolt cutter can easily cut through 13 to 15 mm of metal no matter what kind of metal it was made of.

3. Can the locks be cut?

In short, the answer is yes. However, it depends on various factors such as below.

  • Type of Thieves. Opportunists are thieves that look for easy targets and thus won’t carry advanced and powerful tool. Professionals look for high value targets and carry all the tools needed to do the job
  • Type of Tools. There are many types of tools use to steal a bike, from bare hands to cable/wire cutters, hacksaws, hammers, crowbars, bolt cutters, hydraulic jacks and even portable angle grinders. The good news is, a stronger bike lock requires a more powerful tool to break. This itself is a big deterrent factor.

4. What can I do if I can't find my keys?

Normally, keyed bike locks come with 2 keys, so you can keep the other 1 as a backup. However, it’s not uncommon to see cyclists lose both of those keys.

Luckily, most companies, especially reputable ones provide replacements, assuming you’ve registered your bike locks or remember the key numbers written on the key.
