The 14 Best Bike Locks


Choosing a bike lock seems like one of the simplest decisions and in many ways it is.

When you’re sifting through the best bike locks out there, you need to prioritize only three elements:

  1. Security
  2. Ease of use
  3. Ease of transportation

Before you compare the locks we review today, it is worth first familiarizing yourself with the various different types of bike lock.

  • U-locks: Also known as D-locks, these locks look like jumbo padlocks. This type of lock delivers a great balance between price, performance, and security. The rigidity of these locks can make transportation challenging, but in return you will benefit from a high level of protection and complete peace of mind when you leave you precious bike unattended. If you are only looking to buy one bike lock, make it a U-lock.
  • Chain locks: This type of locks consists of a lengthy metal chain and a large lock. The chain is typically covered by a protective sleeve ensuring that the paintwork of your bike doesn’t get scratched or scuffed. Portable chain locks are usually less than 12mm thick meaning the lock can be wrapped around the seat post or carried in a bag. The length and flexibility of the construction lets you lock your bike to a wider range of objects. Stationary chain locks, by contrast, are typically more than 12mm thick, featuring a thick hardened steel chain and a top-notch padlock. The drawback of this type of chain is the difficulty of transportation.
  • Foldable locks: Foldable bike locks are made from metal plates joined together with rivets. Lightweight and extremely easy to transport, you unfold these locks into a flexible shape, affording more freedom when locking your bike than a U-lock provides.
  • Cable locks: You should avoid using a cable lock as the primary means of locking your bike. These locks are made from multiple strands of steel braided together inside plastic tubing. Although lightweight, flexible, and inexpensive, almost all cable locks can be easily cut with bolt cutters or cable cutters. The best use case for cable locks is as a secondary lock, enabling you to secure your saddle or wheels.

Now you can see at a glance the benefits and drawbacks of each type of bike lock, you should consider the two other most important variables – ease of transport and ease of use.

  • Ease of transport: If you purchase a bike lock that’s too bulky and heavy to easily carry around, there is much more chance you won’t bother using it. A lock should be easy enough to slip into your bag or pannier. Alternatively, you should be able to mount the lock on the frame of your bike for even greater convenience.
  • Ease of use: The best bike locks need to be easy to use, especially if you frequently mount and dismount during the day.

So, make sure the type of lock fits your needs and allows you enough freedom when locking your bike. If it’s also easy to use and carry around, you’ve got a winning recipe! Explore our showcase of the best bike locks out there and protect your investment rather than ending up the victim of bike theft.

The 14 Best Bike Locks

1. Our Pick: Kryptonite New York U-Lock



  • Lock type: U-lock
  • Weight: 4.4 pounds
  • Dimensions: 3.2 x 1.2 x 1.2 inches

First in line and our overall favorite from today’s bike locks is from industry leader Kryptonite.

U-locks offer protection against many different attacks, including pick and drill, twist, and single cut attacks. This is achieved thanks to the disc-style cylinder onboard. Beyond this, double deadbolts serve to engage both ends of the shackle for maximum security.

This model is the New-U, a redesigned version of the original classic. Offering an interior locking area of 4 x 8 inches, the shackle of this lock is made from 16mm hardened steel finished in black and yellow finish.

Designed to ward off assaults from bolt cutters, hand tools, and leverage attacks with crowbars, this lock provides you with first-class protection against most would-be thieves.

Although the manufacturer supplies an anti-theft protection offer for one year, you should read the fine print. Many consumers report adverse experiences when trying to claim cash for stolen bikes under this warranty coverage.

Kryptonite will send you two keys free of charge in the event of loss, ideal peace of mind. You get three keys bundled with the lock, along with an LED fob.

As long as you don’t mind the minor restriction of the small interior locking dimension, this is one of the most effective and easily transportable U-locks out there, so what are you waiting for?

Things We Like

  • Resistant to multiple types of attacks
  • Key safe program offered
  • Hardened steel build

Things We Dislike

  • Some reported issues with insurance

2. Abus Granite XPlus



  • Lock type: U-lock
  • Weight: 4.4 pounds
  • Dimensions: 14.6 x 9.3 x 7.7 inches

Abus has a deep bench of highly effective bike locks, so how does the Granite XPlus U-lock stand and fall?

As with all U-locks, also known as D-locks, the Abus is heavy and pretty bulky. This solidity, though, provides a solid method of securing your bike against most reasonable attacks.

The alloy steel build is finished in a matte black and built to stay the distance.

This model is mis-advertised as featuring a combination lock, one of the most easily conquered of all bike locks. Instead, you get three keys bundled with this lock for added security. You will also get a key code so you can order more keys in the event of loss.

Although the Abus is a weighty lock, you get a bracket included which should fit on most standard bike frames. You might run into trouble if you have a fat bike or mountain bike with a non-standard frame.

This iteration of the Granite XPlus is the uprated version of the gray outgoing model.

With the exception of a few complaints about quality control issues, there is not much to knock about this U-lock aside from its slightly unwieldy nature.

Things We Like

  • Made from rugged alloy steel
  • Bracket included to fit most frames
  • Heavyweight and robust

Things We Dislike

  • Quality control concerns

3. Abus Granite 540 Padlock



  • Lock type: Arch padlock
  • Weight: 3 pounds
  • Dimensions: 1.4 x 6.9 x 11.6 inches

Another Abus lock up next with the Granit 540 arch padlock, looking very similar to a U-lock. How does it perform, though?

Perhaps the key selling point here is the lack of moving parts – there are none except for the locking mechanism itself. This should lead to long-term ease of use without anything going amiss. That’s something that can’t be said for all locks in this class.

Boasting high protection against picking attacks, the 13mm bar is made from hardened steel and coated with a thin layer of rubberized protection. The shackle is equipped with double bolts to ramp up security further. The main strength of this lock comes from the intelligently designed shape.

Hand tool attacks against this lock are liable to prove fruitless. The lock protects against handsaws, hammers, bolt cutters, and wire cutters. As with all bike locks, this model might be beaten by power tools, but it will certainly deter casual thieves.

By the standards of U-locks, this model is reasonably lightweight and pretty easy to transport in a bag or bike pannier.

You’ll get two choices of mount with this model. One of these requires you to lock the lock into the bracket, although this doesn’t prove to be much hassle.

Overall, whether you call this a U-lock or an arch padlock, you’re benefiting from robust protection against most attacks for far less than you might imagine.

Things We Like

  • Strong picking protection
  • Few moving parts
  • Trustworthy brand

Things We Dislike

  • Awkward returns policy

4. Kryptonite Kryptolock



  • Lock type: U-lock
  • Weight: 2.9 pounds
  • Dimensions: 4 x 4 x 9 inches

We have another offering from the inimitable Kryptonite next with the bestselling Kryptolock. How does it shape up, then?

Bike thieves go after bikes in many different ways. This lock provides pretty decent protection against most of those attacks. As with any bike lock, a committed thief equipped with an angle grinder may hit paydirt, but hand tools of any description will be unlikely to break this lock.

By the standard of U-locks, this model is quite light and shouldn’t be an excessive burden when transporting it between uses.

The shackle is made from hardened steel as with all Kryptonite locks and you also benefit from a 10mm steel cable to complete a winning package.

Internal locking dimensions of the Kryptonite are 4 x 9 inches, and the cable is 4 inches long.

Aside from a few glitches with ill-fitting keys, almost all user feedback concerning this bike lock is positive. Kryptonite locks might not be cheap but when you’re buying one of their locks you are making a sound investment in your beloved bike.

As part of this brand’s key replacement program, you are entitled to two keys shipped free of charge in the event of misplacing the lock key.

Things We Like

  • Prevents almost any attack
  • Reasonably lightweight for U-lock
  • Unbeatable brand image

Things We Dislike

  • Some snags with ill-fitting keys reported

5. Master Lock 8170D



  • Lock type: U-lock
  • Weight: 1.96 pounds
  • Dimensions: 9.8 x 7.3 x 1.3 inches

Master Lock is a specialist in this vertical with this U-lock costing far less than you might first imagine.

You first need to choose from several variants. This is the smaller of the two locks offered at 6.125 inches. The larger model measures 7.25 inches.

Made from vinyl wrapped steel, you’ll enjoy all the benefits of a U-lock with the added advantage of a superlight build. Weighing under 2 pounds, this is one of the lightest locks in this class. You’ll get a carrying bracket supplied so you can attach the lock to the frame of your bike if desired.

Fortunately, you don’t sacrifice security to achieve that lightweight form. The body is constructed from hardened steel. The double-locking mechanism ensures the shackle is firmly secured and your bike stands the best chance of evading theft.

The disc key is designed to withstand picking attacks and you’ll get two of these bundled with the lock. Make sure you keep the spare in a safe place!

Not only does this lock deliver outstanding protection against most attacks with the exception of power tools, but it’s also remarkably easy to use. Consider, too, the ease of transportation, and you have a strong contender for the best bike lock out there. As an added kicker, the pricing is in line with more or less anyone’s budget.

Things We Like

  • Outstanding value for money
  • Carrier bracket thrown in
  • Decent anti-pick protection

Things We Dislike

  • Customer service issues reported

6. Kryptonite Evolution



  • Lock type: U-lock
  • Weight: 1.96 pounds
  • Dimensions: 9.8 x 7.3 x 1.3 inches

As you can see from the number of Kryptonite locks we review today, this brand is a powerhouse in this vertical with an impressive range of locks. How does the Evolution compare to the opposition?

Firstly, choose from multiple variations to suit. This iteration features both a traditional U-lock and a steel cable.

Perfect for protecting all types of bikes against pretty much any attack, don’t let the mini size of this lock fool you.

The lightweight nature – it weighs half as much as some locks in this class – means you will never be weighed down by your lock.

Despite the slender form, the 3mm steel shackle is designed to cope with leverage attacks or attacks from hand tools or wire cutters.

The looped cable included allows you to secure your bike even more firmly, or to secure the seat and wheels if you haven’t already done so.

As with all locks from this brand, you can take advantage of a free key replacement service on the first two occasions you lose your bike lock key.

The bracket included gives you the ability to attach the lock to most standard bike frames for even greater convenience.

Things We Like

  • Ideal for warding off most attacks
  • Lightweight and portable
  • Manufacturer ships keys globally in event of loss

Things We Dislike

  • Questionable anti-theft protection policy

7. Ottolock Sidekick



  • Lock type: Compact U-lock
  • Weight: 1.65 pounds
  • Dimensions: 5 x 1.5 x 7.8 inches

If you’re looking for a compact lock but you also want the security of a U-lock, Ottolock offers the Sidekick, one of the strongest options at your disposal.

For anyone tired of bike locks in black or silver, there are multiple vibrant colorways here to match your bike’s paintwork.

That paintwork will also stay free of scratches and scuffs thanks to the protective coating over the hardened steel.

Given the impressive robustness and overall strength of this lock, it’s surprising that it’s also one of the lightest U-locks you can find. If you prize ease of transportation over maximum durability, the Sidekick is well worth a place on your shortlist. There is a larger version of the lock available if you prefer more heft.

The notable drawback well worth pointing out is that many keys will fit this lock, exposing you to a potential security hazard. After all, it is not much use having a solid overall build if the lock has a weak point like this. Buyer, beware.

As with most bike locks, you get a couple of keys thrown in to complete a decent option at a pocket-friendly price, as long as you don’t mind the risk inherent with this lock.

Things We Like

  • Light lock considering its strength
  • Silicone coating to prevent scratches to frame
  • Pair of keys bundled

Things We Dislike

  • Most keys open this lock

8. Kryptonite Kryptoflex



  • Lock type: Double-looped cable
  • Weight: 1.15 pounds
  • Dimensions: 42 x 1 x 2 inches

Yet another Kryptonite bike lock up next in the form of the Kryptoflex.

Now, you should be clear what you’re getting here before committing to purchase – more specifically, you should be clear about what you’re not getting. This is simply a double-looped cable with no lock. Designed for adding extra security to existing Kryptonite locks, this is not a standalone product.

The braided steel cable is a lengthy 41 inches, giving you plenty of freedom when tethering your bike to a fixed object. Use this lock in combination with other Kryptonite locks and you can minimize the chance of anyone making off with your precious bike.

Another great use case for this cable is for locking more than one bike together. Again, you’ll need a method of securing them, but the cable offers you great protection.

The vinyl cover ensures the lock doesn’t scrape the paintwork on your bikes, so you have no concerns on that front, ideal for owners of expensive bikes.

While this cable is no use as a primary lock, it’s well worth adding to your arsenal, especially if you need to secure multiple bikes against most attacks.

Things We Like

  • Useful for locking multiple bikes
  • Compatible with all Kryptonite bike locks
  • Comes with protective cover

Things We Dislike

  • You will need a lock for cable

9. Kryptonite Evolution Mini



  • Lock type: Integrated chain lock
  • Weight: 4.3 pounds
  • Dimensions: 5.75 x 2.5 x 2.4 inches

Kryptonite comes to the fore once again, showing their complete dominance of this market segment with yet another first-class lock.

Now, the Evolution Mini is not designed with the same applications in mind as a heavy chain lock or a rock-solid U-lock. What you’re getting here is a quick and easy way of securing your bike against many different attacks but in a pocket-sized format.

The chain links on this lock are six-sided and constructed from manganese. This chain is covered by a thick protective sleeve, adding strength and safeguarding your bike frame against scuffs and scratches.

The way the links attach to the deadbolt removes one of the most common weak points on this type of lock.

You will find your bike protected against various different attacks, including picking and drill attacks.

You benefit from three keys in this package, one of which features a replaceable LED fob.

The most significant drawback is linked to its scaled down dimensions – it’s cut so short that using it can prove problematic, depending on your intended anchoring.

While this lock does not offer the same level of protection as a more substantial U-lock or chain lock, what you get in return is a marvelously portable bike lock capable of deterring all but the most dogged thieves equipped with power tools – ultimately, there is not much you can do to protect your bike against that kind of attack anyway.

Things We Like

  • Super-simple to transport
  • Pick-resistant and drill-resistant
  • Links made from manganese steel

Things We Dislike

  • Lock is too short for many applications

10. Hiplok Gold Wearable Chain Lock



  • Lock type: Wearable chain lock
  • Weight: 3.3 pounds
  • Dimensions: 18.75 x 2 x 5.5 inches

As we near the end of our bike lock reviews, we have an innovative option from Hiplok in the guise of this wearable lock.

The main differentiating point with this lock is the way it’s designed to be worn around the waist when not in use. If you have a heavy load on your morning commute and you don’t want the added encumbrance of a bulky bike lock, adjust this to fit and wear it like a makeshift belt. The speed buckle attachment ensures the lock will never become locked around your waist, preventing you from needing to pull a Houdini act.

Although the wearable nature of this lock is impressive, any bike lock stands and falls on the strength of the security it offers. For this type of chain lock, you’ll benefit from gold-rated protection against most types of attack.

Covering the robust chain is a thick protective sleeve, further strengthening the lock and guaranteeing that your bike frame remains scratch-free. The sleeve is studded with reflective detailing to help you stay seen at night. You can remove and wash the sleeve for your convenience.

The only minor gripe we can level at this lock is the way it can be prone to rust developing over time. Avoid leaving the lock out in the rain attached to your bike whenever possible.

With three keys included, you should be safeguarded against that most frustrating of experiences – being prevented from unlocking your own bike.

Things We Like

  • Wear around waist when not in use
  • Made from nylon and hardened steel
  • Protective sleeve is removable and washable

Things We Dislike

  • Some reports of rust developing

11. Kryptonite Keeper



  • Lock type: Integrated chain lock
  • Weight: 1.1 pounds
  • Dimensions: 7.9 x 3 x 2 inches

Next up comes another entry from industry legend Kryptonite. As with all locks from this brand, you’ll benefit from enrollment in the key protection program, providing you with two key replacements free of charge in the event of loss.

Choose from a handful of commanding colorways at a reasonable price point and benefit from solid protection against most standard attacks from would-be thieves.

Four-sided 7mm chain links are securely fastened to the deadbolt, offering the ultimate in strength where much of the opposition fails.

The chain is encased by a protective sleeve designed to cope well in adverse weather conditions. You can remove and wash the sleeve to prolong lifespan and keep your lock looking immaculate.

The deadbolt is designed to withstand most incursions and the disc-style cylinder should ward off any drilling attacks.

While this lock might not offer the same level of protection as a more solid and substantial U-lock, you should find it suitable for most commuting purposes and it makes a great choice for anyone prioritizing ease of use and transportation.

Things We Like

  • Several striking color options
  • Two keys included
  • Weather-resistant protective sleeve

Things We Dislike

  • Not the strongest lock

12. OnGuard Mastiff



  • Lock type: Integrated key chain lock
  • Weight: 1.9 pounds
  • Dimensions: 11.5 x 3 x 8 inches

OnGuard offers up an integrated key chain lock that performs similarly to the Kryptonite lock above and is priced in the same territory.

One of the primary benefits of this bike lock is the double-locking mechanism, offering you maximum strength and protection where you need it most.

The chain links are made from lightweight but rugged titanium so the lock can withstand cutting attacks.

The cylinder baked is designed to protect against both picking and physical attacks, giving you close to all-round protection for much less than you might imagine.

Both the cylinder and the crossbar are covered by a heavyweight sleeve, so you don’t need to worry about the paintwork on your bikes getting snarled up.

While the engineering and design of this lock are commendable, the overall build quality and finish is something of a disappointment.

Things We Like

  • Double-locking mechanism
  • Protects against picking and physical attacks
  • Reinforced protective sleeve

Things We Dislike

  • Disappointing build quality

13. FoldyLock Compact Bike Lock



  • Lock type: Foldable bike lock
  • Weight: 1.9 pounds
  • Dimensions: 2.4 x 2.4 x 7.5 inches

Before we wrap up today’s bike lock roundup, we have time for a couple more models, including the FoldyLock.

Available in multiple bright colors, this lock is designed to fold up to a fraction of its size so you can easily slip it in your bag or backpack when not in use.

Perfect for all types of bikes including e-bikes, the FoldyLock also works well for securing scooters.

Guaranteed for three years, this weather-resistant lock should give you plenty of faithful service.

There is a frame mount included and this is designed to secure the lock to your frame without kicking up too much noise.

You get a carry case included along with the master keys and these keys do not require codes.

As long as you understand that you won’t be getting quite the same degree of protection as a U-lock arrives, investing in this innovative light might be the smartest purchase you make for your beloved bike.

Things We Like

  • Innovative and compact foldable design
  • Ideal for bikes, e-bikes, and scooters
  • Wide choice of colors

Things We Dislike

  • Doesn’t offer as much protection as U-locks

14. Abus Bordo Granit



  • Lock type: Foldable bike lock
  • Weight: 1.9 pounds
  • Dimensions: 33.5 x 0.4 x 0.4 inches

Last but not least in today’s showcase of the best bike locks is another entry from Abus in the form of the Bordo Granit. What do you get for your money here, then?

Well, this is another lock boasting foldable technology, making it the ideal choice for anyone unable or unwilling to carry a heavy bike lock around.

The cylinder of the lock is impressive and should withstand a variety of attacks on your bike.

There are two keys supplied with this lock, one of which comes with an LED fob.

Overall construction is hardened steel and the rivets used are designed to make life tough for even the most enterprising thieves. This is more than you can expect from a lock that places convenience uppermost.

Not only is this lock super-portable, but it’s also extremely light considering the overall strength and solidity.

The only notable drawback of this lock is the fact it’s too small to accommodate the frames of most e-bikes. For most other types of bikes, though, this foldable option makes a wise bet.

Things We Like

  • Foldable technology
  • Extremely lightweight
  • Two keys supplied

Things We Dislike

    • Too small for e-bike frames


1) What is the most effective way to use a bike lock?

When locking your bike, lock according to the value of components. Start with the frame and then move to the rear wheel and the front wheel. Any frame and wheels left unlocked are left wide open to thieves. The best option is to lock both bike wheels to the frame using a chain lock or a cable lock. If you are leaving your bike in a high-risk area, consider using a U-lock for this purpose. You can then secure the frame to a fixed object. Leave your bike in a well-lit area if possible. If in doubt, ensure that anything you are locking your bike to is stronger than your bike lock.

2) Which are better, key locks or combination locks?

Combination locks are easy to hack with no tools required. On the plus side, you have no chance of losing a key. A key lock is typically more secure, although you’ll be exposed to the risk of losing your keys.

3) Do many bike thieves try to pick bike locks?

Most bike thieves rely on brute force rather than picking techniques. This means if you invest in a strong lock, you should safeguard yourself against all but pro bike thieves.

4) What is a disc detainer?

A disc detainer is also known as a disc tumbler lock. This type of mechanism features a line of slotted and rotating discs. These discs are separated by washers and each disc features a cutout. When locked, these cutouts will not line up. When you insert and turn the key, this rotates the discs into alignment and forms a channel. This type of lock is highly resistant to picking.

5) What is a pin tumbler?

Pin tumbler locks have a plug sitting inside a cylindrical housing. Both the housing and the plug have lengthy pin chambers. These allows spring-loaded pins to move back and forth between the two. When locked, these pins sit between the housing and the plug, stopping you from turning the plug. When you put the key into the plug, this lifts the pins so they enter the housing or the plug. A gap remains between the two so the plug can turn. The disadvantage of these locks is that they can be easily picked and raked.

6) What is a slider?

Slider locks consist of a series of sliders. These springless sliders are set inside a plug and correspond to an external slot on the plug. Above the sliders is a sidebar. This must be positioned in the slot or you will not be able to turn the lock. When you insert the key and the sliders are positioned correctly, the sidebar will tumble into the slot, allowing the plug top turn inside the cylinder. If investing in this type of lock, look for one with plenty of sliders.

7) What is a wafer?

Usually considered the least secure of all bike lock designs, this type of lock is not unlike a pin tumbler lock. Rather than spring-loaded pins, though, these locks feature rectangular wafers. Prone to picking and raking, these locks can also sometimes be opened with random keys.


A bike lock is crucial for almost all cyclists, especially those reliant on a bike as their main method of transportation. Losing your bike to theft because you don’t have a lock or don’t have a good enough lock is one of the most frustrating experiences, and it can also prove extremely costly.

Today’s guide should help you to confidently pick the right type of lock for your circumstances. As long as you avoid cable locks, you can’t go far wrong with any of the options on our shortlist today.
