As you may already know no bike lock is undefeatable. However, there are a select few that can be considered the strongest bike locks.

The bike locks listed below are the strongest bike locks on the market to date and are guaranteed to make thieves think twice before trying anything funny.

    The Strongest Portable Bike Locks

    Kryptonite Fahgettaboudit Mini – The Strongest Portable Bike Lock

    The Kryptonite Fahgettaboudit sends a clear message to bike thieves. Forget about it! The Kryptonite Fahgettaboudit Mini D lock is easily the strongest portable bike lock available and makes most other D locks look flimsy. 

    This lock features an 18mm hardened max-performance steel shackle. I’ve previously covered how important the thickness of a lock’s shackle is, and Kryptonite have pulled all the stops on this one.

    For a bike lock to be bolt cutter proof, it’s shackle or links need to be at least 16mm thick. There are a few exceptions for some locks, but I stick to this as the general rule of thumb. This doesn’t mean, that locks with thinner shackles or links are no good. 

    Many Sold Secure Gold bike locks have reasonably thin shackles. If you want to make sure your bike lock isn’t going to be cropped, stick to locks that are 16mm thick or more. These are untouchable with all bolt cutters.

    Thanks to its 18mm steel shackle, this D lock will shrug off attacks from even the biggest hand-powered bolt cutters. The super thick shackle also means that it’s a great struggle to start any form of twisting motion. 

    Twist attacks are a technique commonly used by thieves to snap cheaper bike locks. The video above shows how the Fahgettaboudit performs against an advanced pair of hydraulic bolt croppers, impressive huh?

    The Fahgettaboudit also features a high-security double deadbolt system. Put simply, this means at least two cuts would have to be made before your bike could be released. This feature dramatically increases this locks security and overall strength. 

    You may have noticed, the Fahgettaboudit is “mini”. Yes, this D lock is actually rather small compared to others of its type. I use the Fahgettaboudit as my main bike lock and combine it with an extension cable so that I’m easily able to secure my bike’s frame and both wheels.

    The best thing about using a smaller lock is, once your bike is secured there is no room for thieves to insert any tooling. A popular method of stealing bikes is using a small hydraulic car jack. 

    Thieves insert the car jack inside a lock and expand it until the bike lock pops open. The shackle of the Fahgettaboudit is only 8.2cm wide. This means when you secure your bike properly with this lock, you’d be hard pushed to fit anything else inside the shackle and attempt to break it open.

    10/10 Kryptonite Security Rating
    Kryptonite gave the Fahgettaboudit the highest security rating they offer, putting it up there with their strongest bike locks!

     

    With extreme strength, sacrifices have to be made. The Fahgettaboudit weighs in at 2.06kg, making it slightly heavier than most of its size.

    If you want the strongest portable bike lock, the slight increase in weight is a sacrifice you’ll have to make. It’s only 1.1lb (500g) heavier than the other strongest bike locks in my list, and it’s definitely worth the extra weight for the increased security. 

    It’s really no surprise that this 18mm D lock is Sold Secure Gold Rated.The Fahgettaboudit had no trouble gaining the motorcycle Sold Secure Gold rating as well as the Gold bicycle rating!

    The Kryptonite Fahgettaboudit is the strongest portable bike lock available. Period.

    Litelok Gold – A One of a Kind, Super Strength Portable Bike Lock

     

    The Litelok Gold has taken the bike security market by storm. The Litelok Gold uses revolutionary new technology to provide unrivalled protection for your bike.

    This beautiful futuristic bike lock is already breaking records. The Litelok Gold is one of the lightest locks to gain the Gold Sold Secure rating. Weighing in at just 1.1kg, the engineering behind this lock is second to none.

    The LiteLok Gold is 73.6cm long (28.9″) which gives you a locking circumference of 73.6cm (28.9″) and means that you won’t struggle to fit this lock around larger objects. This brightly coloured bike lock also harness’ the new patented material, Boaflexicore. Boaflexicore gives this lock the ability to self-repair. 

    If you somehow managed to make a cut into this lock, the super flexible core would ‘spread and squash’ into the cut you’ve made. This incredible method of self-repair makes it much harder for thieves to defeat this bike lock and made sure it secured its place amongst my strongest bike locks.

    There are several videos available on youtube where a wide selection of tools are used to try and defeat this lock. LiteLok challenged an ironman athlete to defeat their LiteLok Gold. *Spoiler* he doesn’t get far!

    Because it’s so lightweight, the LiteLok Gold is super easy to transport, and even comes with a carry bag which is handy for those travelling without a rucksack.

    Thanks to the shape and design of the alternative model, the LiteLok Wearable, this lock can be worn around the waist as if it were a belt. You’d be hard pushed to find a lock, that is more convenient than this beauty!

    Litelok Wearable the strongest bike lock

    Much like Kryptonite, LiteLok also give customers the chance to register and receive their anti-theft protection offer. Essentially, if you are enlisted in this scheme, and your bike is stolen whilst secured with a LiteLok, you should be able to get your money back. 

    It’s definitely worth having a look at, but make sure the terms and conditions suit you before joining this protection plan.

     

    This scheme shows that LiteLok stand behind the security of their product and are willing to put their money where their mouth is. It’s a great option to have, for people living in areas that have a high risk of bike theft.

    Finally, the price. At the end of the day if you want one of the strongest bike locks it will cost you, and for how practical, versatile and secure this bike lock is, it’s a bargain!

    Abus X-Plus 54 Mini – The Fahgettaboudit’s Lighter Substitute

    ABUS Granit X -Plus 54 Mini Bike Lock

    At almost half the weight of the Fahgettaboudit, the Abus X-Plus 54 mini is the third lock in the list of the strongest bike locks available. It boasts some seriously impressive accolades, such as the Gold Sold Secure rating, what’s more, ABUS rated it 15/15 on their security scale.

    This impressively engineered lock features a 13mm square hardened steel parabolic shackle. You may be now thinking, why would I want a 13mm shackle if it is not bolt cutter proof? You’d be right to think so too! 

    The square shape of the X-Plus 54 Mini is designed to resist bolt cutter attacks. ABUS also made sure to include the upmarket double deadbolt system within this lock, which means two or more cuts are needed before the lock can be removed from your bike. This is a premium feature that only the best and strongest bike locks utilise.

    If you’ve ever tried to cut hardened steel with bolt cutters, you’ll understand how much effort making two cuts through this 13mm square parabolic shackle would be. The chances are, you probably haven’t tried this, but believe me, it’s hard! 

    The video above shows the ABUS Ultimate Mini 420 which uses the same 13mm hardened steel shackle as the ABUS 54 Mini. They both feature the ABUS double deadbolt system, which works flawlessly and drastically increases both lock’s security.

     

    The X-Plus 54 Mini has already featured on the list of the best lightweight bike locks. But for this lock to be included in my list of the strongest bike locks, is one hell of an achievement! Weighing in at just 1.16kg this is a much lighter, yet less secure alternative to the Fahgettaboudit. The size of this D lock means that it can easily be stowed away.

    This lock is the little brother to the Granit X Plus, which is one of ABUS’ flagship models. The great thing about smaller locks, is they are harder for thieves to manoeuvre.

    This D lock measures in at 10.8 x 14cm which allows for plenty of locking space whilst you’re using it. However, once you have secured your bike, due to the “mini” size, there is no room inside the shackle for thieves to play with. Which is exactly what you want from a bike lock.

    For a lock of this standard, you’d expect it to set you back a large sum. But you’d be wrong to think so. The Granit X Mini is one of the cheapest locks in this list, this solidifies second it’s place in the list of the strongest portable bike locks.

    • Weight: 2.68lb (1.22kg)
    • Dimensions: 4.25" x 5.51" (10.8cm x 14cm)

    The Strongest Stationary Bike Locks

    Stationary bike locks are monsters. These bike locks are built to be undefeatable and provide the best possible security for your bike. You’d seriously struggle to carry one of these around, as most are over 5kg!

    However, if you always secure your bike in the same location it can be a great idea to leave one of these secured to an immovable object. By doing so, you’ll always have the best level of security possible.

    It’s important to note that over 50% of bikes stolen are taken from their owner’s home. So make sure that when you secure your bike at home, you are using the best method of protection possible.

    According to reports from the Transport Research Laboratory 50% of bikes are stolen from the owners home!

     

    Stationary chain locks are almost immune to even the biggest hand-powered bolt cutters and aren’t nearly as vulnerable to other attacks as D locks or other portable bike locks are. As these chain locks have a large locking area, they’re immune to most hydraulic attacks.

    It’s important to remember that, your bike lock is only as secure as the object it’s locked to. If you decide on securing your bike with a stationary bike lock, consider using a top-quality ground anchor.

    All in all, these are a better, more secure option for securing your bike, and if you don’t need it to be portable, definitely consider one of these.

     

    Pragmasis Protector 16mm Chain – Strongest Stationary Bike Lock

    Pragmasis Protector 16mm Chain Sold Secure Gold The strongest bike lock chain

    The Pragmasis Protector 16mm is the strongest stationary bicycle chain lock on the market. This chain is made from hardened Boron steel and weighs a whopping 3.02lb per foot (4.5kg per metre).

    This Pragmasis chain received the Sold Secure Gold rating in almost every possible category. From ATV to Caravans and Commercial Vehicles, this chain is capable of securing almost anything. If you need something secured, this will do the job.

    Before we all get too carried away, the Protector is a lot more expensive than the other strongest bike locks. It’s also made to order, so won’t be readily available like the other strongest bicycle locks are.

    Wayne Winton a locksmith and Youtuber put this lock to the test and attempted to cut it with two giant (42″) pairs of bolt cutters. See how he gets on below!

    Supplied with this chain is the Squire Squire SS65CS padlock. This padlock is Sold Secure Motorcycle Gold Rated and provides an easy way to secure this hefty chain. The squire padlock weighs 2.2lb (1kg) making it one of the best heavy-duty, armoured padlocks available.

    When customising your chain at the pragmasis checkout you can make various adjustments (length, end link style and key types). Just like the Kryptonite noose chains, you’re able to add a large circular link/noose onto the end of the Protector Chain. This feature allows you to pass the chain back through itself and increase the chain’s usable length.

    You can also choose exactly what length of chain you require, starting at 2.62′ (0.8m) and working up to 19.69′ (6m). The strongest, best bicycle chain on the market (stationary). 

    Larger Pragmasis chains and Almax chains are available, but with heavier chains than this, you run the risk of damaging your bike. A 16mm chain will be enough to protect even the most expensive bikes.

    If you’re interested in the strongest chain lock, I’ve covered Pragmasis Protector chains in much more detail here.

     

     

    The New York Legend 1515  – The Strongest Readily Available Stationary Bike Lock

    Kryptonite New York Legend 1515 Chain Lock

    It’s worth noting that whilst kryptonite do not produce locks of the same size that Pragmasis do, all of their locks are readily available

    After reading about 16mm bike chains, this 15mm chain may sound like a downgrade. However, I’ve still never heard of a chain this size being defeated by a pair of hand-powered bolt cutters.

    The New York Legend’s chain is made from 3T hardened steel, which “resists bolt cutters”, according to Kryptonite. If you haven’t already, have a look at the video above which puts a 16mm chain lock up against a pair of large bolt croppers. 

    The padlock supplied with this bike chain has a 16mm shackle, made from max performance steel. It also makes use of the double deadbolt design that Kryptonite use on their top of the range D locks. This means that for the armoured padlock to be released, two cuts would have to be made through its shackle (almost impossible).

    The New York Legend 1515 is suitable for all bicycles, most thieves will move on just by the sight of this chain. The 1515 comes with a secure protective nylon cover, to prevent your bike from being scratched and is also supplied with three stainless steel “I” keys for better ergonomics.

    Kryptonite 1515 security ratings the strongest bike lock
    The New York Legend 1515 has gathered top security ratings!

    You won’t be surprised to hear that the New York Legend 1515 gained 5/5 from ART the bike Dutch security testing organisation. This is definitely Kryptonite’s most secure chain lock available, they gave it 10/10 on their security rating scale.

    The chain of this lock is 4.92′ (150cm) long, so it provides plenty of locking space, and can easily be used to secure more than one bicycle.

    If you know that the New York 1515 is too long for you, then the New York Legend 1590 should do the job. This is exactly the same bike lock, but is 23″ (60cm) shorter, and will still resist bolt croppers.

    The 1515 model weighs 15.94lb (7.23kg) whereas the 1590 only weighs 9.5lb (4.31kg). If you’ve only got one bike to secure, then the 1590 will be the better option. But if you are securing two or more bikes the 1515 will be your best bet.

    For those within the UK or Europe, this chain has been hard to get hold of recently. If you can’t get hold of one of these, try the Kryptonite New York Fahgettaboudit 1515.

    Kryptonite New York Noose 1275 – Strongest Portable Chain Lock

    Kryptonite New York Noose 1275

    As always with my reviews, I like giving my readers the full range of options, and this is where the Kryptonite New York Noose 1275 comes into play.

    The New York Noose is a 12mm six-sided chain made with 3T hardened manganese steel and is designed to put up a fight. It weighs 3.15kg, so it’s on the heavy side, but could still be considered portable if you’re feeling strong!

    This chain is secured with what is essentially a super-mini D lock. Its Max-Performance steel shackle is 14mm thick, and it features the double deadbolt design that you’d expect from a larger Kryptonite D lock.

     

    Whilst it may not be the strongest bike lock featured in this list, it is very strong and does not suffer from the same vulnerabilities that many D locks do.

    Whilst 12mm isn’t completely bolt cutter proof, it would be anything but easy to crop this chain! As previously stated, if you can keep your lock off the ground it greatly reduces the locks vulnerability, and will make it much harder for a thief to steal your ride!

    Sold Secure gave the 1275 the Gold rating and ART gave this chain lock 4/5 which means they deem this lock suitable for securing not only bicycles, but mopeds and motorcycles (on the road) too!

    If D locks aren’t for you and you’re able to bear the slight weight increase this is your next best bet!

    Portable and Non-Portable Bike Locks – What’s the difference?

    As you may have noticed, I separated the strongest bike locks above into two categories: Portable bike locks and non-portable bike locks.

    If you’re looking for something super heavy duty for securing your bike at work or at home, then consider a stationary bike lock. These locks are too heavy to carry whilst cycling but provide unrivalled protection. Consider leaving one of these in places that you often leave your bike. 

    However, if you need a super-strong bike lock, that you can slip inside a rucksack and easily transport, then you’ll be best off with a portable bike lock.

    Don't get caught out, get yourself a portable bike lock that you can easily carry!

    Portable bike locks are bike locks that you can keep on you as you travel with your bike throughout the day. D lock’s are an example of a portable bike lock. You’ll be able to comfortably fit these into your rucksack, and it won’t weigh you down.

    Perfect for commuters, couriers, and casual cyclists portable bike locks are the most popular type of bike locks. The Kryptonite Fahgettaboudit Mini is the strongest portable bike lock and is covered towards the top of this page.

    Summary – The Strongest Bike Locks

    So there we have it, the strongest bike locks available to date. I will keep on updating this list as new releases are made, but you can rest assured these locks won’t let you down if you use them to secure your bike properly.
     

    It’s important to remember that no bike lock is undefeatable. However, there are many steps that you can take to make sure yours is as secure as it can be. You should also remember that security comes at a price. If you want to secure your bike with the strongest and best bike lock, it will cost you.

    If you’d rather something more portable, why not check out the best lightweight bike locks?

    Would you secure a £1,000+ bike with a £20 bike lock? Surely not!

    If you ride a nice bike, get yourself a nice lock. It doesn’t make sense to purchase an expensive bike, only to secure it with a £20 lock. Police guidelines are to spend 10-15% of the value of the item on its security.

    So you now know which are the strongest bike locks, take a look at my guide covers the steps you should take before your bike is stolen for tips that will greatly increase your cycle security skills!
