Best Bike Locks of 2020

In short

The lock is an essential protection system to have if you own a bicycle. During the day and at night, it allows you to have peace of mind. In trade, there are several models. Because of this, everyone can find the one that will be suitable for their needs. Whether it’s for long-term or short-term protection, you’ll find the right one for you.

Whether it is for use inside your home or use at a station, you will find several types of locks on the market. The best known are the locks: Evolution Mini-7 from Kryptonite, Foldable Bordo Granit X-Plus from Abus and New York from Kryptonite. In addition to these models, the U Granit X-Plus 54 Abus locks and Evo Serie 4 locks from Kryptonite are also very popular.

Indeed, known for their robustness and rigidity, it should be noted that there are models that are flexible and light. These are compact, transportable and can easily be stored in a cover to be fixed. Besides that, they are quick and easy to use since they are made with materials such as hardened steel shackle and special cemented steel.

However, it should be noted that although they are generally all designed with steel, they do not really have the same characteristics. Each model has its peculiarities and it is these specificities that allow each user to find what suits him.

Moreover, it must be said that their main dissimilarity lies in their weight. The less bicycle locks weigh, the easier they are to transport. The weight of light models varies between 900 grams and 1.5 kilograms. On the other hand, the heavier they are, the more difficult they are to transport. The weight of heavy models is often 5 kg.

Several other criteria such as rigidity, level of security and warranty allow you to choose the best lock, the one that best suits your bike. In short, you must therefore take all these elements into account to make the choice that suits your needs.

The different models of bicycle locks

The bicycle, this ecological and healthy means of transport, often attracts envy, especially in the city. Thefts are more than frequent there, by sawing, twisting or forcing the lock with a bar by leverage.

The bicycle lock is therefore the most effective and practical solution to counter this scourge and deter thugs. On condition, however, to take the model most suited to the type of bike.

The most frequently recommended remains the U-shaped bicycle lock, ie with a handle whose ends are locked in a housing protecting the lock. Indeed, this handle made of a steel of round section is more resistant to break-ins. Note, however, that this design also makes a U-lock heavy and weighs over a kilogram.

Other types of locks include the folding lock. It comes in the form of a carpenter’s yardstick, with flattened steel arms hinged to each other with rivets. In general, due to the thickness of said arms, it will resist a bike thief a little less.

There is also the “chain” lock, made of steel links joined by a padlock: this makes it more vulnerable than a U-shaped lock, the lock of which is embedded in a block.

The class of anti-theft devices also includes “cable” (or “snake”) anti-theft devices. They are made of braided steel wires, coiled or not, wrapped in a protective plastic sheath (usually transparent, for an illusion of thickness). This type of lock has a version with a cable protected in a steel frame, called an articulated cable, “boa”, “python”, more resistant to the section than the basic cable lock. The length and flexibility are the main advantages of this type of lock. However, they are easier to remove than the other lock models mentioned above.

How to choose your bike lock?

A bicycle lock serves as a protection system, but it must still be suitable for the bicycle in question. It is therefore necessary to take into account the following aspects to choose the most suitable for your bicycle:

The anti-theft locking mechanism

We mentioned above the fragility of a padlock in the face of possible assaults by a thief. Then check that the anti-theft locking system is effective, but also practical. It should not get stuck after a while of use. Also make sure that it is well protected from the elements. Rust can easily unbalance a lock’s interlocking mechanism.

The dimensions of the lock

Whether you choose a U-lock, folding lock, or hinged lock, make sure that its length can allow you to secure your bike to anything that could serve as a stand. Because you won’t always have a bike rack available, or a bike rack with hoops to hang your bike on. 

You need to consider all the elements that could be used as a bicycle parking space: post, tree, guardrail (the handrail, either the horizontal part to which you hang, or one of the posts, one of the vertical bars at the bottom guardrail). 

Depending on the support available, your lock should therefore allow you to secure your bike to its support (upper frame tube – support, down tube and / or fork + front wheel – support, seat tube and / or seatstay + rear wheel – support, etc.).

At the same time, make sure that the lock does not damage the paint on your bike. Certainly, it should not dangle (which would guarantee the absence of scale). However, a protective coating against direct contact between the metal of the frame and the steel of the lock would be well thought out.


The comparison of the 5 products selected by the editorial staff shows that the Evolution Mini-7 lock from Kryptonite represents the safest alternative.

Indeed, only its Flexframe support is criticized in fact. No mention was made of the lock being blocked. Of course, this lock is small compared to other models. However, the 4 ‘Flex cable makes it possible to reinforce the safety of the bicycle.

Finally, the protective coating of the lock is a significant bonus. Regarding its transport, the support provided by the manufacturer is fragile, but with its 1.6 kg and its 18cm, it will easily fit in a bag.
