    The Best Bike Lock – 8 Top Rated Bicycle Locks

    OnGuard Brute STD 8001

    The Best Cheap Bike Lock

    OnGuard Brute Bike Lock



    OnGuard Brute Specifications:

    Security Rating – Sold Secure Diamond
    Weight – 1.86kg (4.1lb)
    Locking Dimensions – 11.5 x 20.2cm (4.53 x 7.96″)
    Shackle Thickness – 16.8mm Hardened Steel
    Warranty – Lifetime

    The OnGuard Brute is the first bike lock in our list of the best bike locks. This bike lock recently took first place in my review of the best cheap bike locks and brushed aside the competition.

    If you worry about your bike whilst you’re away from it, the OnGuard Brute’s whopping 16.8mm hardened steel shackle resists even the most brutal attacks.

    The Brute was one of the first locks on the market to receive the Sold Secure Diamond rating, which wasn’t a surprise to me. 

    The Diamond rating means the OnGuard Brute sits alongside some of the most secure bike locks on the market.

    OnGuard Brute Rubber Padding

    Bike locks with shackles/links wider than 16mm can be considered bolt cutter proof, so the OnGuard Brute joins this exclusive club of locks that are immune to even the largest 42” bolt cutters.

    The OnGuard Brute is significantly more affordable than most of the other best bike locks, and is ideal for cyclists who’re a budget.

    Whilst it’s the cheapest lock featured in this review, it’s not made with the highest quality materials.

    Compared to the LITELOK X1 or the Kryptonite Fahgettaboudit Mini, the Brute will require more regular maintenance as it’s more prone to rust and corrosion. 

    OnGuard Brute with extension cable
    The Brute offers plenty of locking space and is suitable for securing valuable bikes in high-risk areas.

    The Brute is not as strong as the Granit Extreme 59, which you can read about towards the bottom of the page.

    That being said, are aware of how secure the OnGuard Brute is. OnGuard gave the Brute a 97/100 rating for its security, which makes it their most secure bike lock.

    Whilst your bike is locked with the Brute, most thieves will move onto an easier target.

    You can view the most up to date and competitive price for the OnGuard Brute here [Amazon].

    Otherwise, to find out more about this strong, affordable D lock, I’ve reviewed the OnGuard Brute in much more detail here.

    Foldylock Compact

    The Best Folding Bike Lock

    Foldylock Compact before and after destruction testing review



    Foldylock Compact Specifications:

    Security Rating – Sold Secure Silver
    Weight – 1kg (2.2lb)
    Shackle Length – 85cm (33.5″) 
    Shackle Thickness – 5mm Hardened Steel
    Warranty – 3 Years

    If you’ve already read about the best folding bike locks or the best lightweight bike locks, you’ll be familiar with the Foldylock Compact [Amazon link].

    Folding bike locks are designed for cyclists who need a lock that provides increased portability, whilst retaining a respectable level of security.

    The Foldylock Compact achieves the above with ease. It’s the lightest Sold Secure Silver folding bike lock on the market.

    Weighing 2.2lb (1kg), this compact folding bike lock is the lightest of the best bike locks.

    Whilst not in use, the Compact can be folded down and inserted into its mounting bracket for a comfortable, silent transport method.

    Compact mounted with plastic straps
    The Compact is now supplied with reusable zip ties which are ideal for when your bottle mounting positions are already in use

    The Foldylock also offers more locking options than the OnGuard Brute and LITELOK X1 thanks to it’s 33.5” (85cm) hardened steel, flexible shackle.

    The Foldylock Compact [Amazon Link] provides impressive protection for a lock of its weight and size. However, you do receive slightly less protection than when using a D lock.

    Each 5mm hardened steel plate the Foldylock uses is capable of resisting an enhanced toolkit and can repel more determined attacks.

    The Foldylock is ideal for use on the move and perfect for commuters.

    benefits of folding bike locks
    The Foldylock Compact provides more internal shackle space than most D locks and can secure your bike to larger immovable objects like this street light

    For a bike lock that’s so versatile, you’d be surprised to find out how affordable the Foldylock is [Amazon Link].

    It’s not as cheap as the OnGuard Brute but is one of the cheaper locks featured in this review.

    The Foldylock is suitable for use in low-medium risk areas. Or, when locking your bike in high-risk areas, use the Compact for shorter periods of time.

    If you’re sick and tired of carrying an awkwardly heavy bike lock, this is the best bike lock for you.

    Otherwise, if you know you want a folding lock but aren’t sure about the Foldylock Compact, read my review of the best folding bike locks.


    The Best Angle Grinder Resistant Portable Bike Lock



    LITELOK X1 Specifications:

    Security Rating – Sold Secure Diamond (Bicycle & Motorcycle)
    Weight – 1.7kg (3.75lb)
    Shackle Dimensions – 10 x 19.2cm (3.94 x 7.56″)
    Shackle Thickness – 17mm Fine Grain Hardened Steel
    Warranty – 3 Years

    Today’s Best Deals:

    The LITELOK X1 is the latest angle grinder-resistant bike lock to hit the market, and with the ever-rising price of bikes, the X1 has been a popular choice for cyclists since its launch in October 2022. 

    The LITELOK X1 uses Barronium, a patented anti-grinder technology that contains tiny ceramic particles.

    If a bike thief were brave enough to cut through the X1’s shackle, small ceramic particles fused to the outside of the 16mm fine-grain steel shackle would turn the grinding disc on itself, quickly disintegrating or fragmenting the entire disc.

    I attended the LITELOk X1 launch event, where several others and I had the chance to cut the X1 and see how effective it is. 

    LITELOK X1 Angle Grinder Testing
    A guest at the LITELOk X launch event attempting to cut the X1's shackle (unsuccessfully!)

    After six attempts and six disintegrated cutting discs, we finally made the first cut through the X1’s shackle.

    Bear in mind each of us cut a new section of the shackle, but this demonstrated just how effective Barronium is at repelling attacks carried out with an angle grinder.

    Thieves using angle grinders on the street won’t usually carry replacement cutting discs or batteries, so the X1 has a high chance of beating grinder-wielding thieves. 

    LITELOK X1 Shackle after angle grinder testing
    Three unsuccessful cuts through the X1's armoured steel shackle at the LITELOK X launch event

    After watching six failed attempts, I successfully cut through the LITELOK X1’s shackle in 1 minute and 57 seconds.

    We then compared the X1’s performance to the Kryptonite Fahgettaboudit Mini, which has long been one of the best D locks on the market. A single cut through the Fahgettaboudit’s shackle took 15 seconds. 

    Fortunately, the X1 and Fahgettaboudit Mini both utilise dual-locking anti-rotation shackles, meaning at least two cuts are required through the shackle before a bike can be released.

    In addition, both tests were conducted in lab conditions, using a vice to hold either lock.

    How heavy is the LITELOK X1
    Weighing 1.7kg (3.75lb) the X1 is perfect for use on-the-go.
    How heavy is the Kryptonite Fahgettaboudit Mini
    The Fahgettaboudit Mini weighs in at 2.04kg (4.49lb), substantially heavier than the X1 and with less grinder-resistance.

    Cutting either of these locks would have been considerably more challenging if the locks weren’t held in place, and the X1’s disc shredding capabilities would be dramatically amplified.

    The X1’s only competitor is the Hiplok D1000, which is heavier and nearly double the price, retailing at $290 (£250) on the Hiplok website. 

    I had previously been using the Seatylock Mason to secure my bikes, but I’ve swapped it out for the X1, which provides unrivalled peace of mind.

    If you worry about your bike whilst you’re away from it, there isn’t a better option. 

    You can read my in-depth review of the LITELOK X1 here or check the latest price on the LITELOK website. 


    The Only Vomit Inducing Bike Lock



    Skunklock Specifications:

    Security Rating – Not Rated
    Weight – 1.77kg (3.92lb)
    Shackle Dimensions – 10.8 x 22.9cm (4.25″ x 9.03″)
    Shackle Thickness – 19mm Hardened Steel (partially hollow)
    Warranty – 30-Days

    The Skunklock is a revolutionary, one-of-a-kind bike lock. It was the first bike with the ability to fight back against thieves and is super effective at stopping them in their tracks.

    At the core of the shackle, there’s an 11mm hollow area which is filled with a pressurised vomit-inducing compound.

    If a thief cuts through to the core of the 19mm hardened steel shackle, the pressurised compound will rapidly disperse into the surrounding area, temporarily incapacitating the thief and sending them running (and spewing!).

    Skunklock double bolted shackle
    (Click to enlarge)

    Seeing as it’s so secure, I was interested to find out why the Skunklock hadn’t been put forward for Sold Secure testing.

    After speaking with Daniel Idzkowski, the entrepreneur behind Skunklock, he let me know why:

    “After having six bikes stolen whilst using Sold Secure Gold locks in San Francisco (over five years), I did my research, and the reality is professional thieves don’t waste their time with the majority of methods they (Sold Secure) test.”

    Skunklock vs bolt cutters
    Even my large 24" bolt cutters were unable to encompass the Skunklock's thick shackle.

    The Skunklock’s 19mm shackle is immune to almost all forms of attack. Whilst it doesn’t use Barronium armouring like the LITELOK X1 the smell of its pressurised compound will make thieves wish they’d taken on an easier target.

    There isn’t another lock on the market similar to the Skunklock, its appearance and huge health-warning label will be enough to deter most thieves. 

    The Skunklock’s innovative anti-theft technology means it retails at a higher price than most D locks. If I’m honest, I’d go for the LITELOK X1 over this as it retails at a similar price and offers better all-round security. 

    Best Bike Lock Mount for Skunklock = Huldit Large
    The Huldit Bike Lock Mount provides an effective and affordable way to transport the Skunklock.

    If you enjoy taking the idea of fighting back against bike theft, the Skunklock could be the lock for you.

    Unlike other brands, the Skunklock can be bought directly from the SKunklock website. You can view pricing and additional information on this top-rated bike lock here [Skunklock website].

    Kryptonite Evolution 1055 Mini

    The Best Bike Chain Lock (Portable)

    Kryptonite 1055 Mini



    Kryptonite Evolution 1055 Specifications:

    Security Rating – Sold Secure Gold & ART 3/5
    Weight – 2kg (4.4lb)
    Chain Length – 55cm (21.5″)
    Shackle Thickness – 10mm Hardened Steel
    Warranty – Lifetime 

    If you like the security that D locks (U locks) offer, but need a larger locking area for your bike a chain lock is probably the best option for you.

    The Kryptonite Evolution Series 4 1055 Mini is a Sold Secure Gold, ART Level 3 certified bike lock that provides a similar amount of shackle space to your average D lock.

    Whilst the 1055 uses a 21.5” (55cm) shackle, which is relatively short for a chain lock, it does offer an increased number of locking options compared to smaller D locks.

    Also thanks to its shorter length, the 1055 remains portable, weighing just 4.4lb (2kg). When I reviewed this top-rated bike lock, I didn’t struggle to fit it into my backpack.

    Series 4 1055 Mini in Backpack
    Alongside other items, I was easily able to fit the 1055 Mini into my backpack. Perfect for commuters!

    This is one of the best chain locks I’ve reviewed. It’s suitable for commuters and cyclists who are constantly on the move, and will lock your bike safely to most objects.

    The Kryptonite 1055 Mini bike chain lock uses 10mm hexagonal, manganese steel links.

    Hexagonal links provide a higher level of security than regular circular chain links, thanks to the increased area of their cross-section.

    Kryptonite rated the 1055 Mini at 8/10 on their in-house security scale. This means that the 1055 Mini bike chain lock is suitable for locking your bike in high-risk areas (busy cities & university campuses).

    Before After

    Whilst it’s heavier, the 1055 Mini offers more security than the Foldylock Compact. It’s also able to encompass large objects, that D locks would struggle with (see slider above). 

    If you’re looking for the most secure chain possible, keep reading. I cover the best and strongest (stationary) bike chain later in this list.

    If you need a chain you can take everywhere with you, the 1055 is the bike lock you need.

    The 1055 Mini retails at a very reasonable price [Amazon] when you consider it’s Sold Secure Gold rated and ART Level 3 certified.

    Read my complete review of the 1055 here if you’re considering this top-rated bike chain lock.

    Kryptonite Fahgettaboudit Mini

    The Original Bolt Cutter Proof  D Lock




    Security Rating – Sold Secure Bicycle Diamond, Sold Secure Motorcycle Gold & ART 4/5
    Weight – 2.04kg (4.49lb)
    Locking Dimensions – 8.3 x 15.3cm (3.25 x 6″)
    Shackle Thickness – 18mm Hardened Steel
    Warranty – Lifetime

    In 1994 Kryptonite released the Fahgettaboudit to tackle rising bicycle theft rates in New York. Since then, the Fahgettaboudit has become one of the most popular locks on the market, and for good reason!

    Like the OnGuard Brute, the Fahgettaboudit Mini uses a bolt cutter-proof shackle. However, the Fahgettaboudit’s 18mm shackle is much stronger and made using higher-quality hardened steel.

    The Fahgettaboudit is Kryptonite’s strongest and best D lock to date.

    Whilst this is a highly secure D lock, unlike the LITELOK X1 the Fahgettaboudit doesn’t feature any anti-grinder technology, which does leave it more vulnerable to angle grinder attacks.

    Kryptonite Fahgettaboudit Mini hardened steel sleeve
    (Click to enlarge)

    The Fahgettaboudit uses higher-quality materials than the OnGuard Brute, which justifies its more expensive price. If you can afford the extra money, the Fahgettaboudit will last you longer.  

    Thanks to the Fahgettaboudit’s Sold Secure Diamond Bicycle rating, Motorcycle Gold rating and ART Level 4 certification, capable of securing your bike in high-risk areas where thieves operate.

    Before I swapped over to the LITELOK X1, I’d been using the Fahgettaboudit Mini as my main D lock for over three years.

    I never had a problem when using it and no thieves targeted my bike. Possibly because they understand how strong this lock is!

    How to lock your bike with the kryptonite fahgettaboudit mini
    Whilst the Fahgettaboudit is smaller than other D locks, it offers just enough room to secure your rear wheel and frame.

    Measuring 3.25” x 6″ (8.3cm x 15.3 cm) the Fahgettaboudit is the perfect size for securing one bike.

    If you ride an e-bike or a bike that’s going to attract attention from thieves, I’d recommend the LITELOK X1 over this, otherwise, the Fahgettaboudit retails for roughly half the price of the X1, so is a better option for those with a tighter budget. 

    You can view the most up-to-date price for the Fahgettaboudit Mini on Amazon here

    I’ve produced a more in-depth review of the Fahgettaboudit here, have a read If you’re interested in finding out more. 

    Kryptonite New York Legend Chain 1515

    The Best Bike Chain Lock (Stationary)



    Kryptonite 1515 Specifications:

    Security Rating – Not Rated
    Weight – 6.6kg (14.7lb)
    Shackle Length – 150cm (59.05″)
    Shackle Thickness – 14.5mm Hardened Steel
    Warranty – Lifetime

    Today’s Best Deals:

    The Kryptonite New York Legend Chain 1515 is the best (stationary) bike chain lock on the market and one of the most secure bike locks (that’s readily available).

    Kryptonite state themselves that the 1515 New York Legend is their strongest chain, which provides ultimate security in high-risk areas.

    Each 14.5mm 3 tonne hardened steel link, provides incredible protection against all forms of attack.

    Due to the quality of the metal used to forge each 14.5mm link, it would be almost impossible to defeat this chain without the use of power tools. 

    The Best Bike Chain Lock - New York Legend 1515 14.5mm links
    Whilst the 14.5mm links aren't thick enough to be considered bolt cutter proof, it would be extremely difficult to cut this chain by hand!

    Kryptonite’s New York Disc lock secures either end of the New York Legend Chain. The Disc lock uses a 16.5mm hardened steel shackle, which is essentially a smaller version of the Kryptonite Fahgettaboudit Mini.

    This is the best bike chain on the market for securing multiple bikes at once. If you need a bike lock to secure your bike’s in your garage, or in your biked shed, there isn’t a better (readily available) option.

    Obviously, this chain lock isn’t portable like the 1055 Mini. However, if you cycle to the same destination each day, leave this chain where you lock your bike up.

    By leaving the 1515 chain locked at your destination, you’ll have access to the top-rated bike chain lock and incredible levels of security when you arrive. Ideal!

    The Best Bike Chain Lock - New York Legend 1515 locked at destination
    If you're a commuter, leave the Kryptonite 1515 locked at your daily destination. This way you'll always have access to top-quality security!

    This is the best bike lock for garages and bike sheds. If you need a lock that can safely secure multiple bikes, this is the one.

    Bear in mind that this chain is expensive due to the large amount of high-quality hardened steel it uses. That being said, I did find it at a very reasonable price on Amazon, here.

    Otherwise, you can read more about the best bike chain locks here.

    ABUS Granit Extreme 59

    One of the Strongest Bike Locks 



    ABUS Extreme 59 Specifications:

    Security Rating – Sold Secure Diamond
    Weight – 2.7kg (5.95lb)
    Shackle Dimensions – 26 x 11cm (10.2 x 4.3″)
    Shackle Thickness – 16mm Hardened Steel
    Warranty – 2 Years

    The ABUS Granit Extreme 59 is one of the strongest bike lock on the market and easily cemented its place in the list of the best bike locks.

    Before I tell you any more, I have to tell you, the Extreme 59 is expensive [Amazon link]. It’s specifically designed for high-value bicycles and motorcycles, but doesn’t offer any anti-grinder technology like the LITELOK X1 provides.

    This D lock is for people who are constantly worried about the security of their bike, and need a lock that’ll send thieves in the other direction.

    In terms of security, the Granit Extreme 59 sits in a similar category to the Kryptonite Fahgettaboudit Mini.

    It’s bolt cutter proof, dual locking and Sold Secure Bicycle Diamond and Motorcycle Gold rated, meaning the 59 is suited for use in the highest risk areas. 

    The strongest bike lock - sheldon brown locking method abus 59 extreme
    The ABUS Granit Extreme 59 is capable of securing multiple bikes effectively, in high risk areas. I was easily able to secure two of my bikes using the Sheldon Brown locking method.

    It’s worth noting, the LITELOK X1 sells for a similar price to the Extreme 59 and utilises anti-grinder technology that the ABUS 59 lacks.

    Sold Secure awarded the Granit Extreme 59 the prestigious Sold Secure Diamond rating, as well as the Sold Secure Motorcycle Gold rating.

    If you lock your bike in areas with a high risk of theft, this is a fantastic choice. The shackle provides plenty of space for securing extra accessories and is also capable of securing more than one bike.

    If you need to secure more than two bikes, I’d suggest the New York Legend 1515 Chain.

    The strongest bike lock - Extreme 59 vs fahgettaboudit shackle size
    The Extreme 59 and the Fahgettaboudit Mini offer similar levels of security. The Fahgettaboudit's reduced size makes it the more portable choice.

    Weighing 5.95lb (2.7kg), this is a heavy D lock. That being said, my Huldit Bike Lock Mount allows me to attach the Extreme 59 to the frame of my bike, so it can easily be transported when cycling.

    If you need to secure two bikes simultaneously, the 59 is your most suitable option, but if you’re securing a single bike, the LITELOK X1 will provide increased security for a lower price.

    Check the most up-to-date price for the Extreme 59 here on Amazon.

    Kryptonite Kryptoflex 710

    The Best Cable Bike Lock



    Kryptonite Kryptoflex 710 Specifications:

    Security Rating – N/A
    Weight – 0.52kg (1.1lb)
    Shackle Length – 213cm (7′)
    Cable Thickness – 6mm Braided Cable
    Warranty – Lifetime

    If you were thinking of using a cable lock as your primary bike lock, please reconsider!

    Cable locks provide a minimal level of security for your bike.

    Instead of using a cable lock as your primary bike lock, read my review and use one of the best cheap bike locks. The locks featured in this review are super affordable and provide much better security for your bike.

    I’d only recommend using a cable lock alongside a reputable bike lock. Cable locks are suitable for securing the accessories of your bike (wheels, saddle, seat post etc.) so don’t get caught out!

    Evolution Series 4 1055 Mini with cable extension
    The Kryptoflex 710 offers enough room to secure your front wheel and saddle.

    The best cable lock I’ve found is the Kryptonite Kryptoflex 710. This essentially acts as an extension to your bike lock and prevents thieves from stealing your valuable components.

    The Kryptonite Kryptoflex 710 will work well with any of the best bike locks featured in this review.

    Buying the Kryptoflex 710 will be much cheaper than having to replace components that get stolen, so you’d be foolish not to use one!

    Kryptonite Kryptoflex 710 in backpack
    The Kryptoflex is lightweight and requires minimal space in a backpack. Use one!

    You can view the cheapest price I could find online for the 710 here [Amazon], every cyclist should use a cable extension. 

    I use the Kryptonite Kryptoflex every time I leave my bike secured in a busy public area and wouldn’t hesitate to recommend it.

    If you’re curious to find out more about how the Kryptonite 710 cable extension works, have a read of my more detailed review.  

    How to Choose The Best Bike Lock For You?

    With so many different makes and models of bike lock to choose from, finding the best bike lock for your situation is a nightmare.

    The graph below gives a brief overview of each type of lock. I gave each type of lock a rating for each characteristic and rated them from 1-10. 10 means high, 0 means low.

    Best Bike Lock Comparison Chart

    Below I’ll walk you through the different types of bike lock and what each lock type is suitable for in a bit more detail.

    If you didn’t know which was the best bike lock for you after comparing the locks above, this short guide will help you find the lock you need in no time.

    Different Types of Bike Lock & Their Uses

    D Locks (U Locks)

    Kryptonite Kryptolok Mini 7

    D locks, also known as U locks, are the most common type of bike lock.

    They’re common for a reason, they offer well-rounded security, whilst being highly practical and remaining relatively cheap.

    This is the type of lock that most cyclists use, including me.

    Most D locks come with a mounting system that will allow you to attach them to the frame of your bike.

    For D locks that aren’t supplied with a mount, the Huldit Bike Lock Holder is the best way to take your bike lock with you, when cycling.

    Their solid metal shackles, do prevent D locks from securing your bike to some larger objects, such as thick lampposts. But it’s never hard to find something else you can lock your bike to.

    If you want to be able to secure your bike to any object, a folding bike lock would be a better choice.

    Chain Locks

    Chain locks are another popular choice for cyclists. Chain locks are normally used at home (in bike sheds & garages) to lock your bikes overnight. This is because they’re often too heavy to carry.

    Chain locks are long and are normally suitable for securing multiple bikes.

    Most chain locks are heavy, but there are shorter more portable chains such as the Kryptonite 1055 Mini, featured above.

    Due to the increased amount of metal used, chains tend to be more expensive than D Locks. Only stationary chains with thicker links provide similar security to D locks. 

    I’d recommend the Kryptonite New York Legend 1515 to anyone who needs a super-secure chain for their bike shed or garage.

    Otherwise, if you’re constantly on the move with your bike, a D lock will be a better choice.

    I’ve reviewed the best chain locks on the market. Have a read.

    Folding Bike Locks

    Folding bike locks offer a compromise between security and practicality.

    Folding locks offer a similar number of locking options to a chain lock, and similar levels of security to D locks, whilst remaining highly portable.

    The Foldylock Compact is the best folding bike lock, but not the strongest. If you’d like to read about the best folding bike locks, read my comparison review here.

    Folding locks are one of my favourite types of bike locks. I’d recommend you use a folding lock if you don’t like carrying a lot of weight whilst cycling.

    Folding locks are easily the most practical type of bike lock!

    Cable Locks

    Cable locks are cheap flimsy locks, and you should never use one as your primary bike lock.

    Instead, use a cable lock alongside your primary bike lock to secure extra accessories.

    Cable locks are a great way to secure expensive components of your bike, such as wheels, that you were unable to secure with your primary lock.

    Whilst cables provide an extremely minimal level of security, they’re good for deterring opportunist thieves.

    Cable locks are also very affordable and lightweight, so are easy to carry whilst cycling.

    Thieves won’t hesitate to steal an unsecured wheel, or your seatpost from your bike.

    Don’t get caught out! The more components you secure, the better.

    The Kryptonite Kryptoflex 710 [Amazon Link] provides a great way to secure extra components. I use this cable whilst locking my bike outside.

    How to Choose The Right Sold Secure Rating

    Bicycle security ratings are confusing. Below I’ve put together a simple flow diagram that will help you find the most suitable security rating for you and your bike!

    If you’ve bought a bike lock before, the chances are you’ll have seen the Sold Secure rating badges. But it’s not very clear what they mean!

    I spoke with Guy McCaffery, the Sold Secure Lab Manager, who was happy to talk me through each rating.

    The Sold Secure ratings are as follows:

    Sold Secure Bronze – Bronze-rated locks offer theft resistance against a basic tool list (aimed at preventing opportunist crime).

    I don’t recommend Sold Secure Bronze locks on BikeLockWiki. They don’t provide enough security to be used as a primary bike lock.

    Sold Secure Silver – Silver-rated locks offer theft resistance against an enhanced tool list (aimed at preventing more determined attacks).

    Sold secure silver locks offer a compromise between security and cost. You can read more about the best Silver rated locks here.

    Sold Secure Gold – Gold-rated locks offer theft resistance against a higher selected tool list (aimed at preventing dedicated attacks).

    Sold Secure Gold locks are top-quality locks that will provide great levels of protection for your bike. Find out more about Gold rated locks here.

    Sold Secure Diamond

    Sold Secure Diamond – Diamond-rated products offer attack resistance against a higher complete tool list (aimed at preventing the highest motivated attacks).

    Diamond rated locks are the most secure and will protect your bike from the most brutal attacks. The OnGuard Brute is the cheapest Diamond-rated lock!

    As Sold Secure Bronze locks only provide a very minimal level of security, you won’t find them recommended on BikeLockWiki.

    I only recommend the use of Silver or higher rated locks as your primary bike lock.

    Bronze rated locks are not worth your money. All of the best cheap bike locks will provide better security, whilst costing the same as most bronze rated locks!

    Summary - The Best Bike Lock

    So there you have it, the 9 best bike locks available on the market.

    When deciding which were the best bike locks, I took all aspects into consideration; Security, Practicality & Price.

    Several of the locks included in this review are more affordable, such as the OnGuard Brute

    However, as we’re talking about the best bike locks on the market, most are more expensive.

    If you’ve got the budget to cover it, I strongly recommend using two locks to secure your bike.

    Hopefully you now understand a few of your options when it comes to choosing the best bike lock for your needs. 

    If your bike attracts second looks, I’d recommend a Gold or Diamond-rated lock. You might think they’ll all be super expensive, but you’re wrong.

    The OnGuard Brute is one of the best cheap bike locks and is also Sold Secure Diamond rated!

    If you have the budget for it, the LITELOK X1 provides the highest levels of security at the most affordable price, there isn’t currently a better all-round option. Read my in-depth review here.

    Understanding how devastating it is to have a bike stolen, I've researched & immersed myself in the world of bicycle security since 2013.

    I then built BikeLockWiki in 2019 to share everything I'd learned with the worldwide cycling community so that cyclists can improve their bike security skills and make informed decisions when purchasing new products and services.

    1. I’d take a look at the Pragmasis SFB-DIB D-Lock. The medium one is 3.4×7.5 (it comes in 3 different shackle lengths while all have the same across diameter and 16mm shackle. For 70 bucks, I feel like it would make it on your list somewhere around the Abus Granit mini/Krypto NYC. Pragmasis also makes some of the best but heaviest chains. It’s a lock I don’t see mentioned much anywhere. For my personal use I use a Knog Strongman/Kryptolock series 2 v1, and a Hiplok v1. Might be adding the Pragmasis or Abus to my lineup soon and retiring the Kryptolock.

      1. I agree. The Pragmasis DIB D lock is definetely one of my favourites. For me, it was between the Pragmasis DIB and the OnGuard Brute. Both of these locks offer great levels of security and whilst the DIB D Locks are built using higher quality materials, the OnGuard Brute is cheaper and readily available in most countries.

        I produced a full review of several pragmasis chains and locks here, have a read if you’re interested.

        How have you found the Knog Strongman? I’ve heard mixed reviews about their locks, which are now a challenge to find for sale.



    2. I am using ABUS product, very satisfied with this bike lock. The outstanding feature of this chain lock is its exceptional security design. I was impressed by the square-shaped links, which are different from the usual rounded standard chains. I feel that the design will be more effective in preventing theft from attacking and cutting this chain type.

      1. Thanks for sharing! Do you know the model of the lock you use so that other readers can take a look?



    3. I like the sound of onguard brute. Have you been using it a lot? I did see a few negative reviews that it jammed up after a while, especially in bad weather. And on a locked bike it is then costly to remove. I need something that will be used a lot because I use the bike for deliveries

      1. Hi Hasan,

        The OnGuard Brute is a high-security, affordable choice of lock. I’ve used the Brute with several of my bikes and haven’t had an issue so far. Yes It’s made from lower-quality materials than a more premium lock like the Kryptonite Fahgettaboudit, but if you lubricate it frequently with some finish line or silicon grease, you shouldn’t have any issues with rust.

        Normally those that end up with a lock jammed to their bike have not maintained it properly. So as long as you clean and lubricate properly, you should be fine!



    4. Hi James,

      I am a product design student and we are are completing a research product into bike lock usage from students mainly aiming towards the decisions of – practicality such as mounting or in bags, cost (as budget is a big consideration) and practicality with laptops etc.

      I wanted to thankyou for this amazing resource. We will properly reference you work and would be great if we could have an email to ask you any questions or share our findings.

      Thanks again,


      1. Hi Archie,

        Great to hear from you! Sounds like an interesting project, one that I’d be happy to help with where possible.

        I’ve dropped you an email so you’ve got mine.

        Thanks for the feedback, if you need specific lock advice, I’ve reviewed loads of locks individually!

        Speak soon,


    5. With thieves using cordless angle grinders to cut through locks in a minute or 2, does it matter if these lock are good against bolt cutters etc.

      The elephant in the room is the cordless angle grinder.

      1. An interesting point Steve. I’d say that whilst angle grinders are becoming a more common weapon of choice for thieves, there are still many out there that don’t use power tools.

        On top of this, the longer a lock takes to cut through with an angle grinder, the lower the chances of success are for the thief.

        If we resort to using cheap cable locks or thinner U locks, it’s likely that bolt cutters would become more popular with thieves and we’ll be back where we started.

        Would you agree?
