5 Best Bicycle Locks To Keep Your Bike Safe

Cycling is a great way to get exercise, enjoy the outdoors, and even commute to work. However, with the rising popularity of cycling, the risk of bike theft has also increased. In fact, according to the FBI, over 188,000 bicycles were stolen in the United States in 2019. This is why it’s crucial to invest in a high-quality bicycle lock to keep your bike safe and secure. With so many different types of locks available, it can be overwhelming to choose the right one. In this article, we will highlight the 5 best bicycle locks on the market to help you make an informed decision and ensure your bike stays where it belongs – with you.


A U-lock, also known as a D-lock, is a popular type of bicycle lock that features a U-shaped shackle made of hardened steel. The shackle is designed to resist cutting and prying, making it difficult for thieves to break through. U-locks are available in a range of sizes, allowing them to fit around the frame, wheel, and an immovable object, such as a bike rack or a pole.

One of the main advantages of U-locks is their durability and strength. They are typically made of hardened steel and can withstand a variety of attacks, including bolt cutters and hammers. They are also easy to use, with a simple locking mechanism that can be secured with a key or combination.

However, U-locks can be heavy and bulky, making them less convenient to carry around. They may also not be suitable for larger bikes or those with wider frames.

When choosing a U-lock, it’s important to consider the size and thickness of the shackle, as well as the locking mechanism. Look for locks with a Sold Secure rating, which means they have been independently tested and certified for their security level.

Some of the best U-lock options on the market include the Kryptonite New York Fahgettaboudit Mini, the Abus Granit X-Plus 540, and the OnGuard Brute STD.

Chain lock

A chain lock is another popular type of bicycle lock that features a chain made of hardened steel links. The chain is typically covered with a sleeve to protect the bike’s frame from scratches, and it can be secured around the frame, wheel, and an immovable object, such as a bike rack or a post.

Chain locks offer a high level of security and flexibility, as they can be used to secure bikes of different shapes and sizes. They are also relatively lightweight and portable, making them a good choice for those who need to carry their lock with them.

One of the main disadvantages of chain locks is that they can be vulnerable to bolt cutters if the links are not sufficiently thick or made of hardened steel. They can also be more difficult to lock and unlock than other types of locks, which can be frustrating if you’re in a hurry.

When choosing a chain lock, look for models with thick and hardened steel links, as well as a secure locking mechanism. Some popular options include the Kryptonite New York Chain, the Abus Granit City Chain X-Plus 1060, and the Hiplok Gold. It’s also a good idea to check the Sold Secure rating to ensure the lock has been tested and certified for its security level.

Folding lock

Folding locks are a type of bike lock that offers the convenience of portability and the security of a U-lock or a chain lock. They consist of a series of metal plates or bars that fold together like a tape measure and can be easily carried in a backpack or mounted on a bike frame.

Folding locks typically feature hardened steel plates or bars that are resistant to cutting and drilling. They also have a secure locking mechanism, such as a disc detainer or a combination lock. Some models may also have additional security features, such as anti-pick covers or alarms.

One of the main advantages of folding locks is their compact size and portability, which makes them ideal for commuters or those who need to lock their bike up in different locations throughout the day. They can also be easier to use than other types of locks, as they can be wrapped around the bike frame or seat post without needing to find an anchor point.

When choosing a folding lock, look for models with a high-security rating, such as the Abus Bordo Granit X-Plus or the Foldylock Compact. It’s also important to consider the length of the lock and whether it will fit around your bike and the anchor point you plan to use.

Cable lock

Cable locks are a popular type of bike lock that use a long steel cable with a locking mechanism to secure a bike to an anchor point, such as a bike rack or a post. They are often lightweight and flexible, making them easy to transport and use.

Cable locks come in different thicknesses and lengths, and they typically use a combination lock or a key lock. They can be made from a variety of materials, including steel, braided steel, and titanium. While they are generally less secure than U-locks or chain locks, they can be a good option for low-risk situations or as a secondary lock in conjunction with a stronger lock.

When choosing a cable lock, look for models with a thick cable and a secure locking mechanism. Avoid models with plastic components that can be easily broken or cut. It’s also important to consider the length of the cable and whether it will fit around both your bike and the anchor point you plan to use.

While cable locks are a convenient and portable option, it’s important to remember that they are not as secure as other types of locks and can be easily cut with bolt cutters or cable cutters. As such, they are best suited for low-risk situations, such as quick stops at a coffee shop or for securing less expensive bikes. For higher-risk situations, consider using a U-lock or a chain lock.

Smart lock

Smart locks are a newer type of bike lock that use Bluetooth or Wi-Fi technology to allow for keyless locking and unlocking through a smartphone app. They often use a combination of sensors and encryption to ensure that only the owner of the lock can access it.

Smart locks offer several advantages over traditional locks. For example, they eliminate the need for physical keys, which can be lost or stolen. They also allow for remote unlocking, which can be useful in situations where you need to give someone else access to your bike, such as a friend or family member.

Some smart locks also offer additional features, such as GPS tracking and tamper alerts. This can be especially useful in high-risk areas where bike theft is common.

However, smart locks also have some drawbacks. They can be more expensive than traditional locks, and they require a smartphone with the compatible app to use. They also rely on batteries, which can die at inopportune times and render the lock useless.

When choosing a smart lock, it’s important to look for models with strong encryption and a reliable app. It’s also a good idea to consider the battery life and whether the lock offers additional features such as GPS tracking.

Overall, smart locks can be a convenient and secure option for those who are comfortable using technology to secure their bike. However, they may not be the best choice for everyone and should be carefully considered before making a purchase.

In conclusion, choosing the right bike lock is essential to keep your bike safe from theft. With a variety of options available, including U-locks, chain locks, folding locks, cable locks, and smart locks, it’s important to consider your specific needs and usage patterns when selecting a lock.

For maximum security, it’s recommended to use two locks of different types, such as a U-lock and a cable lock, to deter thieves. Additionally, locking your bike in a visible, well-lit area and removing any accessories or quick-release components can also help prevent theft.

Ultimately, investing in a high-quality bike lock is a small price to pay for the peace of mind that comes with knowing your bike is secure. By taking the time to choose the right lock and use it properly, you can help ensure that your bike remains safe and protected for years to come.


Can I use the same lock for multiple bikes?

It’s not recommended to use the same lock for multiple bikes, as each lock is usually keyed differently and the keys may not work for both bikes. It’s best to invest in a separate lock for each bike.

How long should my bike lock be?

The length of your bike lock will depend on the size and shape of the objects you plan to lock your bike to. It’s generally recommended to choose a lock that is long enough to secure both the frame and one or both wheels to a solid object.

Are smart locks worth the investment?

Smart locks can be a convenient and easy-to-use option, but they may not offer the same level of security as traditional locks. It’s important to research and choose a smart lock with strong security features and to use it properly.

Can cable locks be cut easily?

Yes, cable locks can be cut easily with bolt cutters or other cutting tools. They are generally not recommended for high-security situations.

What is the most secure type of bike lock?

While no lock is completely foolproof, U-locks and chain locks are generally considered to be the most secure types of bike locks.
