The Best Folding Bike Locks

So, you’re wondering which is the best folding bike lock. When it comes to folding bike locks, there aren’t many models that have received a Sold Secure rating.

Throughout this short article, I’ll talk you through the best quality and most secure folding bike locks on the market. I’ll also help you decide which folding works best for you.

Currently, as it stands there isn’t a huge selection of Sold Secure rated folding bike locks available. This is mainly because folding locks are still a relatively new concept.

If you’re looking for a new bike lock and would like a broader range of recommendations, read my review of the best bike locks or the best uncuttable bike locks.

There are both advantages and disadvantages of using a folding bike lock, but overall, the pros do outweigh the cons.

I use one of the folding bike locks I’ve recommended below almost daily and have never had an issue with it!

Overview - The Best Folding Bike Lock

People who opt for a folding bike lock are obviously after a versatile, portable lock that will provide a good level of security for their bike.

None of the 4 best folding bike locks are bolt cutter proof, which means you’ll want the lock that offers the best security to weight ratio.

Weighing a mere 2.2lb (1kg) the Foldylock Compact is a super lightweight folding bike lock that offers security comparable to many quality D locks. Every feature of the Foldylock Compact has been optimised to perfection.

foldylock compact - the best folding bike lock

The Foldylock offers 33.5″ (85cm) of locking space, which is enough to secure both wheels & the frame of any bike. The Foldylock Compact is super user friendly and folds down into a small package that doesn’t weigh you down whilst you cycle.

For these reasons, the Foldylock Compact is the best folding bike lock on the market to date.

    Why You Should Use a Folding Bike Lock

    Folding bike locks have quickly become a popular choice within the cycling community because of their practical, compact, folding design.

    No one wants to lug around a bulky bike lock whilst out riding. Heavy locks are awkward to transport and even if you were to stow one away in your rucksack, it would be uncomfortable to carry.

    Folding bike locks can easily be attached to your bike's frame, to provide convinient and secure transport.

    The best folding bike locks come with a well-designed mounting system that allows you to easily attach and transport your folding lock whilst cycling.

    Some mounts are better than others, have a read to find out which works best for you and your bike below.

    Folding bike locks also give you the ability to secure your bike to almost anything. If you’re using a D lock to secure your bike, it’s likely that from time to time you’ll encounter an immovable object too large to secure your bike to. Simply because the solid metal shackle is just too narrow.

    Before After

    With folding bike locks, shackle space isn’t an issue. This is because each plate is secured with a rotating rivet that allows the lock to easily fold around larger objects.

    The best folding bike lock weighs less than the best D lock and gives you more locking room.

    Compared to the majority of D locks, folding bike locks do offer a small increase in locking room. The difference is marginal, but this difference can be very helpful at times!

    Disadvantages of Using a Folding Bike Lock 

    If you haven’t used a folding bike lock before, it may take some time to get used to operating one. Most folding locks have a similar but slightly different design, which means their operation is not as straightforward as a classic D lock.

    However, after using a folding bike lock for a week or so you’ll soon be used to the way it works.

    Every bike lock should be kept clean and given regular maintenance to stop parts from deteriorating.

    Moving parts often stiffen up over time due to a build-up of grime, a quick read of my bike lock maintenance guide and you’ll have no problems with your lock.

    Due to their compact design, folding bike lock’s plates are not as thick as the shackle of a D lock. This means that the best folding bike lock isn’t as secure as the best D Lock.

    However, the practical features that folding locks offer, make up for their few disadvantages. Next, we need to find out which security rating will work best for you and your bike …

    Selecting Which Security Level Suits You Best

    So now that you know about the security ratings, you’ll need to find out which rating suits you and your bike the best. Using the flow diagram below you’ll be able to work out which Sold Secure rating you require. 

    You’ll notice that I don’t mention Sold Secure Bronze. This is simply because bronze rated locks only ‘offer protection from opportunist thieves’. This quite simply isn’t a suitable level of protection for any bike.

    Using the flow diagram below, you should be able to determine which rating suits you best. 

    None of the best folding bike locks are bolt cutter proof, so the difference in security between the Silver and Gold rated locks is marginal. 

    Below I’ll give you an insight into the security that the 4 best folding locks provide. 

    The Best Folding Bike Locks - Top 4

    So now you’ve decided which sold secure rating you require we can move onto the best folding bike locks. As I’ve already covered, there aren’t many Sold Secure rated folding locks available, so your choice is fairly limited.

    Below I’ve built a comparison table that will allow you to compare each lock’s features. Beneath the table you’ll find a more detailed review of each folding lock.

The 100dB alarm will help to attract the attention of passers by if your bike is tampered with whilst locked and will help to scare off thieves who try anything funny. Its large shackle offers increased locking space and can be used to secure multiple bikes at once. With its Sold Secure Silver rating and practical, easy access mount, the ABUS 6000A is great for regular use.
    Weighing 2.2lb (1kg) the Foldylock Compact offers the best security to weight ratio and is the best folding bike lock. This precision engineered folding lock stands out for its usability and is very affordable compared to other folding locks. With its anti-drill cylinder and VSR protected rivets the Foldylock knows how to put up a fight and is Seatylock’s best creation yet. If you need a lightweight, versatile, secure bike lock, look no further.
    The Bordo Granit XPlus 6500 is easily one of the most secure folding bike locks on the market. ABUS gave it 15/15, their Maximum Security rating and it’s one of their most secure locks to date. German engineering is known to be some of the best and it shows in the build quality of this folding lock. It’s designed to last. It’s the heaviest folding lock by nearly 0.4lb (0.2kg) and isn’t quite as smooth to operate as the Trelock FS 500 or Foldylock, but offers Sold Secure Gold security to its users.
    The Trelock FS 500 is the best Sold Secure Gold folding bike lock. It's 1lb (0.45kg) heavier than the Foldylock, and is much less compact when folded, which makes it less suited for everyday use. However, the Toro’s 5.5mm TREDUR steel plates offer slightly more protection for your bike. This lock feels more premium than the XPlus 6500 and is much less rattly. If security is your number one priority, this is the folding lock you need.

    These are the best folding bike locks available. Below you’ll find a detailed breakdown of each folding bike lock, highlighting their strengths and weaknesses.

    If you’d rather read about other types of bike lock as well, read my review of the 8 best bike locks.

    The Best Sold Secure Silver Folding Bike Locks

    ABUS Bordo Alarm 6000A - Top Quality Folding Lock With 100dB Alarm Feature

    The ABUS Bordo Alarm begins a new era of bicycle security. I’m not aware of another folding lock on the market that offers an alarm feature. This 100dB alarm greatly adds to the security of this impressive folding lock.

    The Bordo Alarm folding bike lock is 35″ (90cm) long and provides 10.1″ x 4.65″ (25.8cm x 11.8cm) of usable locking space. The 5mm metal plates that this folding lock use are made from specially hardened steel and provide great resistance to cutting, prying and freezing attacks.

    ABUS Bordo Alarm 6000A vs Foldylock Compact shackle size
    The ABUS Bordo Alarm has the largest shackle area of the four folding locks covered in the article. But it is also the largest when folded away.

    ABUS gave this lock 10/15 on their security scale, which lands this lock in the lower end of their ‘Maximum Security’ category. The Bordo Alarm received the Sold Secure Silver rating and provides a compromise between security and cost.

    If someone was to fiddle with your bike or this folding lock whilst it was in use, it would let off a short pre-alarm warning. Normally this will be enough to startle thieves and scare them off. However, if they were to ignore the pre-alarm warning, they would be met with a 100dB sharp acoustic alarm.

    (See video below for alarm test run – this is only an example of how the alarm system works!)

    When I tested the alarm feature myself, I didn’t find it deafening, but it is definitely very loud.

    The alarm is easily loud enough to grab people’s attention, which increases the likelihood of thieves being caught. The chances are thieves will be startled by the loud alarm and will target a less secure bike.

    The mount that comes with the Bordo Alarm 6000A is secure and uses two spring-loaded clips to keep the lock in place whilst in transport. Mounting instructions are supplied, which are fairly straightforward to follow.

    The mount that’s supplied with the Bordo Alarm is easily the best to operate. Simply press on the spring-loaded clips to both remove and secure your folding lock. Check the video below to see just how easy this is. You can also secure this lock to the drinks bottle mount of your bike, or to the seat tube if needed.

    When cycling the mount isn’t completely silent, and if you listen carefully you can hear the lock quietly rattling around. It’s really nothing that will affect usage, but I’m aware some people would prefer a silent ride.

    This lock comes with two coded keys, which you can order replacements for. You can also order this bike lock to be ‘keyed alike’ to other ABUS locks, which is handy if you already use ABUS security products.

    This folding bike lock and it’s mount weigh 3.28lb (1.49kg) together and could easily be carried in a rucksack if preferred. This is slightly heavier than the Foldylock featured below, but with the impressive alarm feature this lock was always going to weigh slightly more.

    All in all, a great choice of folding bike lock. The Bordo 6000A uses a loud, high pitch alarm system, that should give you extra peace of mind whilst leaving your bike unattended.

    If you’re considering this folding lock, take a look at the Sold Secure Gold folding locks below, these locks retail at a very similar price. Definitely worth a look.

    Key Benefits:

    • Loud alarm scares thieves
    • Sold Secure Silver (bicycle) rating
    • Large locking area
    • Specially hardened steel plates
    • Fantastic mounting system
    • Competitively priced 

    Foldylock Compact - The Best Folding Bike Lock

    The Foldylock Compact is another genius invention from the team at Seatylock. I was pleasantly surprised by the impressive build quality of the Foldylock.

    The Foldylock Compact is 33.4″ (85cm) long and provides 9.4″ x 4.5″ (24cm x 11.5cm) of locking space for your bike. This means the Bordo Alarm Provides slightly more locking space than the Foldylock.

    I actually found that the extra locking space the Bordo Alarm offers isn’t necessary. I was able to secure both of my wheels and my bike’s frame using the Foldylock without any issues.

    Also, because the shackle is slightly smaller it left considerably less room for thieves to attempt to pry or twist the Foldylock open.

    Foldylock Compact secured to bike
    The Foldylock Compact provided a secure, snug fit around both of my bike's wheels and it's frame.

    The Foldylock on its own weighs 2.2lb (1kg) which makes it the lightest Sold Secure Silver folding bike lock on the market!

    For a lock of its weight, the Foldylock Compact provides incredible security. It’s 5mm hardened steel links are the same thickness as the Abus Bordo Alarm’s and provide resistance from all forms of attack, including bolt cutters.

    The packaging of the Foldylock Compact boasts ‘silent ride’ which I was eager to put to the test. The Foldylock’s mounting cage was very easy to attach to my bike’s water bottle mount. You receive two screws in the box and even the Allen key to tighten them with! Impressive.

    The Compact comes with everything you need to get it set up. Even the hex key and screws are included.

    Just as it says on the box, the Folylock Compact stays completely silent whilst riding. No rattling whatsoever. Bonus points for those who (like me) prefer a silent ride.

    The mount is made from super lightweight hardened plastic and weighs roughly 3.2oz (100g). This means the Foldylock and it’s mount only weigh a 2.43lb (1.1kg). Crazy lightweight!

    If you use your water bottle mount for a bottle holder, don’t worry. Instead, you can use the rubber-lined velcro straps to secure the mount to your bike’s frame.

    Foldylock compact folding lock mounting device
    Using the strap mount system you're able to secure the Foldylock almost anywhere on your bike. All of the best folding locks come with straps for mounting.

    The plastic coating that encapsulates the Foldylock’s steel links, prevents this folding lock scratching your bike’s paintwork. This hard layer of plastic also protects the Foldylock from unwanted wear and tear and will keep it rust-free.

    Seatylock rated this folding bike lock at 14/18 on their security scale, which puts it in their silver category. The Compact is Sold Secure Silver rated and probably sits in the upper half of this category when compared to other Sold Secure Silver bike locks.

    Because the Foldylock’s plates are only 5mm thick, it provides slightly less protection than a Sold Secure Silver rated D lock. However, due to its flexible shackle, you’re able to sure your bike to many more objects than a D lock would be able to.

    Another fantastic choice of lock, easily earning its place amongst the best folding bike locks.

    If you want to learn more about the Foldylock Compact, check out its detailed individual review.

    Key Benefits:

    • Rattle free silent mount
    • Sold Secure Silver (bicycle) rating
    • Super lightweight 2.4lb (1.1kg)
    • Anti-scratch casing
    • Perfect for commuting
    • Hardened steel plates

    The Best Folding Bike Lock - Sold Secure Silver

    Choosing between the Bordo Alarm and the Foldylock Compact is a relatively easy decision for me.

    The ABUS Bordo Alarm 6000A features an impressive alarm, that will scare most thieves away, or even better, get them caught. Its mounting system is top quality and it’s super easy to operate. However, it’s heavier than the Foldylock Compact and costs considerably more.

    The Foldylock Compact is a great example of precision engineering. The lock feels solid, it’s mount is silent when riding, and for me it provided the perfect amount of locking space.

    The cylinder of the Foldylock is a serious challenge to pick and I really struggled to find any issues with this folding bike lock. Whilst the Foldylock doesn’t offer an alarm feature, it’s more suited for everyday use due to its lighter weight and more compact design.

    The Foldylock is the best all-round folding bike lock covered in this review. But the Bordo alarm is a great choice for those who require the extra peace of mind that its alarm feature supplies.

    The Best Sold Secure Gold Folding Bike Locks

    ABUS Bordo Granit XPlus 6500 - Super Reliable Portable Security

    The ABUS Bordo 6500 is ABUS’ most secure folding bike lock yet. This impressive lock received 15/15 on ABUS’ security scale, which shows it’s much more secure than the Bordo 6000 despite being in the same ‘maximum security’ category.

    The Granit XPlus received the prestigious Sold Secure Gold Bicycle rating and is one of the only two folding bike locks to receive this accolade. Its Sold Secure Gold rating means the ABUS XPlus 6500 is suitable for use in high-risk areas.

    The Bordo Granit is slightly heavier than the Sold Secure Silver folding locks, weighing in at 3.48lb (1.58kg) on its own and 3.79lb (1.72kg) when weighed together with it’s mount.

    The Bordo’s extra weight comes from the thicker 5.5mm specially hardened steel plates that the Bordo Granit utilises.

    This extra plate thickness makes the XPlus much more resistant to bolt cutter attacks than the Sold Secure Silver folding locks shown above.

    The Bordo Granit 6500 is 0.5mm thicker than the silver rated folding locks. It may not sound like much, but you can see the difference in this comparison. Extra thickness = Extra security.

    When unfolded, the Bordo Granit provides 8.9″ x 3.9″  (22.6cm x 10cm) of locking room, making this lock slightly smaller than the Sold Secure Silver folding locks.

    However, the difference in size is small and the reduced size adds to this lock’s ability to resist twisting and prying attacks.

    The X Plus 6500 feels super sturdy and when I first started using this lock I was impressed with how much time and effort had been put into its design.

    The complete outer shell of the ABUS Bordo Granit 6500 is lined with a soft, yet durable rubber coating which eliminates the chances of this lock scratching your bike.

    The tough rubber coating on the outside of the XPlus provides fantastic protection for your bike's paintwork and prevents the lock from the elements!

    The mount that you receive with this folding bike lock is easy to operate and attaching it to your bike is very straightforward.

    This lock can be mounted using either the velcro straps (included in box) or using your bike’s water bottle mount, which tends to be more secure.

    Two keys are supplied with the Granit XPlus, one of which features a bring LED light for operation in the dark.

    This is the only lock in this list of the best folding bike locks that has this useful feature, which can save you from scrambling around in the dark!

    Using ABUS' bright LED key fob I was able to effortlessly lock and unlock my Bordo Granit XPlus.

    Unlike the Foldylock Compact, you don’t receive any screws to mount the Bordo Granit with. It’s likely however, that your bike will already have the screws in place but it’s worth checking in case you need a pair!

    Whilst riding with the mount in place I did notice a very quiet rattling, but this wasn’t as loud as the Bordo Granit 6000.

    I used this lock for over two years prior to writing this review and never had any issue with it. For the extra weight you have to carry, the Granit XPlus is worth it. It offers an increased level of security, and rivals many of the strongest bike locks.

    This lock retails at a very similar price to the Sold Secure Silver folding locks. So, if you were thinking of getting a Sold Secure Silver lock, it may not be a bad idea to opt for this instead!

    • Maximum Security 15/15

    Trelock FS500 Toro - Strongest Folding Bike Lock & Quality Engineering 

    Not many cyclists have heard of Trelock before, so it may surprise you to hear that they have been producing bicycle security products since 1854!

    This is the only other folding bike lock to have received the Sold Secure Gold rating that I know of and is definitely one of the best!

    The Trelock FS500’s 5.5mm thick are made from TREDUR speciality steel, which provides impressive protection against all forms of attack.

    Alongside its mount, the FS500 weighs 3.41lb (1.55kg) making it a lighter alternative to the ABUS XPlus 6500.

    ABUS XPlus 6500 vs Trelock FS500
    The Trelock FS500 Toro is slightly longer than the ABUS Bordo Granit, however, it's actually the lighter lock of the two weighing in at just 3.45lb (1.56kg)!

    “Special deep link bolts with TRELOCK Security Link Technology as well as the TREDUR®-special steel, resist even the most brutal breaking attempts”.

    The Trelock FS500 is 35″ (90cm) long, and it provides 10.2″ x 4.92″ (26cm x 12.5cm) locking room, which is Bordo Granit XPlus, which will be helpful if you need to lock two bikes at the same time.

    Like the other locks I’ve covered, you’ll be able to attach the FS500 to the water bottle mount, allowing for quick and convenient usage.

    You can also use the supplied plastic straps to attach it anywhere else on your bike, these are noticeably more secure than the Velcro straps supplied with the other three folding bike locks.

    Trelock FS500 review - FS500 Toro securing two bikes
    Using the FS500 Toro I was able to secure two bikes at the same time. Both frames and rear wheels safely secured! Impressive.

    The mount supplied with the FS500 Toro is very robust and provides a secure way of transporting this folding lock.

    Attaching this mount to your bike is super easy and I’ve had no trouble operating it. Simply slide the Toro folding bike lock inside the hardened plastic shell and pull the strong rubber strap over the securing clip.

    Unfortunately, this lock isn’t completely silent like the Foldylock Compact, which makes the Foldylock Compact the only silent folding bike lock reviewed in this article.

    Compared to the ABUS Granit XPlus the Trelock FS500 make a similar quiet rattling noise whilst riding, but this doesn’t affect either locks usage in any way.

    I managed to get hands-on experience with the Trelock FS500 Toro after writing this article. Since then I have been using this folding lock daily to secure my bike and haven’t been able to find a single issue.

    This lock isn’t supplied with an LED key, but it does feature a very useful auto-locking feature, which is helpful when operating this folding lock in the dark (see video above).

    Instead of having to fully insert the shackle before you can twist the key to secure this lock, you simply push the shackle in and the auto-locking feature takes care of the rest for you!

    This lock feels incredible, it operates smoothly, and utilises top-quality materials, to provide incredible security for your bike. I’m seriously considering using this lock as my secondary bike lock, instead of my ABUS Bordo Granit 6500. 

    If you’re interested in finding out a bit more, check out my in-depth review of the FS 500.

    Key Benefits:

    • Sold Secure Gold (bicycle) rating
    • Auto-locking feature
    • 2/5 ART rating
    • Suitable for use in high-risk areas
    • 5.5mm TREDUR® steel plates
    • Anti-scratch soft coating

    The Best Folding Bike Lock - Sold Secure Gold

    Both of these Sold Secure Gold folding bike locks will provide fantastic security for your bike.

    The ABUS Bordo Granit XPlus is a top-quality folding bike lock and will survive even the most brutal attacks. I’ve been using this lock for the past two years, alongside the Kryptonite Fahgettaboudit (one of the best D locks) and have never had an issue with it.

    The Trelock FS500 Toro does not disappoint. I had heard good things prior to testing this folding lock, and it has lived up to and exceeded my expectations.

    I’ve recently swapped out the Granit X-Plus for the FS500. The FS500 also offers a larger locking area, whilst weighing in less than the XPlus.

    Trelock FS500 vs ABUS Bordo Granit
    The Trelock (Left) provides more locking space than the ABUS 6500 (Right). Very useful when securing multiple bikes.

    The Trelock also retails at a substantially cheaper price than the ABUS 6500, making it the more affordable of the two locks.

    Both of these folding locks received 2/5 stars from ART and Sold Secure Gold Bicycle ratings. So the security they offer appears to be very similar.

    If you’re looking to purchase a new folding bike lock, I’d recommend the Trelock.

    The Trelock FS500 weighs less, costs less and gained the same security ratings as the ABUS Bordo Granit 6500, making it the obvious choice of the two locks.

    Sold Secure Ratings Explained

    Sold Secure are a non-profit organisation, set up by the Master Locksmiths Association to test and review the security of different security products. For bicycles, the three security ratings available are bronze, silver and gold. 

    • Bronze Sold Secure bike locks only offer defence against opportunist thieves. Bronze-rated locks have passed testing, but have gained the lowest rating and shouldn’t be used to secure your bike for long periods.
    • Silver Sold Secure bicycle locks offer ‘a compromise between security and cost’. Silver is the next level up from bronze and will provide more security for your bicycle.
    • Gold Sold Secure rated bike locks are the best of the best. This is the highest security level and therefore the most secure option when it comes to bicycle security. These locks are suitable for use in ‘high risk’ areas. 
    When purchasing a new bike lock keep an eye out for these Sold Secure rating badges. We'll decide below which rating suits you best!

    Summary - The Best Folding Bike Lock

    So, these are the four best folding bike locks on the market to date.

    People use folding bike locks for their portability and their impressive strength. Currently, your choice is fairly limited when it comes to Sold Secure rated folding bike locks.

    It’s important to remember, with the right tools and enough time, any lock can be defeated. This means you should choose a bike lock that narrows down the options for a thief.

    There isn’t a folding bike lock that’s bolt cutter proof. This means the only real difference between the Silver and Gold rated folding bike locks is the extra 0.5mm of steel plating.

    The 4 Best Folding Bike Locks Reviewed

    This extra 0.5mm of metal will provide a slight increase to the time it takes for a thief to cut through the Gold locks compared to Silver, but drastically increases their weight.

    As you’ve probably already read, out of these four, the Foldylock Compact is the best all-around folding bike lock. It offers a great balance of portability, security and usability all obtainable for a very reasonable price [Amazon link].

    If none of these folding locks are suitable for you, then check out some of my suggestions below.

    The best D lock will provide more security for your bike than any folding bike lock, so have a read.
