    The Top 5 Best Lightweight Bike Locks

    With thousands of bike locks to choose from, presenting you ‘the best lightweight bike lock’ is a challenge.

    However, by studying design quality and getting hands-on experience with a number of lightweight bike locks I’ve have been able to narrow it down to my top 5 best lightweight bike locks.

    These locks all offer different security ratings, which I’ll talk more about later. If you’re unsure which security rating you need for your bike, I’ve explained this towards the bottom of the page. 

    Let’s get into it.

    Foldylock Compact - The Lightest Sold Secure Silver Folding Bike Lock

    The Foldylock Compact is one of the best folding bike locks on the market.

    Despite the use of heavy-duty steel rivets and extra-tough steel links, the Foldylock Compact weighs in at just 2.2lb (1kg). Making the Foldylock the lightest Sold Secure Silver folding bike lock!

    Normally with bike lock security the common rule you can follow is, the thicker the shackle, the more secure the lock.

    However, the Foldylock seems to defy this rule with its sleek, simple design which features 5mm hardened steel links and ultra protected steel rivets.

    Whilst it offers great security, it’s not as secure as the ABUS 54 Mini. But offers increase portability thanks to its folding shackle.

    The Foldylock Compact provides enough space to secure two bike's frames and rear wheels, better than almost any D lock!

    Folding bike locks are a relatively new concept, and not many have gained a Sold Secure Rating, let alone the Sold Secure Silver rating

    I recently carried out an in-depth review of the Foldylock Compact and found that it was my favourite folding bike lock on the market. 

    I used the Compact whilst working as a cycle courier, and it worked a dream for short quick stops.

    Deliveroo with Foldylock Compact
    The Compact performed excellently whilst I worked as a cycle courier. It's completely silent whilst riding and when folded down it doesn't get in the way.

    Its Sold Secure Silver rating means the Foldylock Compact is a medium security bike lock and is suitable for medium security lockups.  

    If you’ve invested a large amount of money in your bicycle, I’d be hesistant to use the Foldylock for long term or high-risk lock-ups.

    A Sold Secure Gold lock, such as the 54 Mini (below) would be more suitable.

    Instead, use the Foldylock for whilst you’re out and about and not away from your bike for too long. For medium length lock-ups, this lightweight folding lock will do you proud! 

    The Foldylock is ideal for commuters. It folds down super easily into a compact shape and won’t take up much room at all in your rucksack. You could even fit this folding bike lock into your pocket!

    Seatylock, the company behind the Foldylock clearly invested a lot of time into the mounting system that the Foldylock uses.

    This mounting system is one of the first that I’ve tested, which doesn’t allow the lock to rattle when stowed away. I hate rattling noises when I ride, so this was a real luxury. 

    For its excellent usability, I think the price the Foldylock retails at is a good deal. You should definitely consider the Foldylock Compact if you’re looking for a versatile lightweight bike lock.

    Seatylock’s attention to detail and incredible engineering behind this lock guaranteed its place in my top 5 best lightweight bike locks.

    I’ve put together a more detailed review of the Foldylock compact, if you’re interested, have a read!

    ABUS Granit XPlus 54 Mini - The Best Lightweight Bike Lock

    With it’s Sold Secure Gold rating, 15/15 ABUS security rating and it’s 13mm square hardened steel parabolic shackle, you’d be surprised to hear that this D lock weighs a mere 1.16kg (2.56lbs).

    As explained before, I wanted to make sure our recommended “lightweight” bike locks were actually lightweight. The 54 Mini is lightweight compared to most locks but is the heaviest of the best lightweight bike locks. 

    It may be slightly heavier, but the 54 Mini is the most secure lock covered in this review. If you’re looking for a combination of security and portability, the ABUS 54 Mini is the lock for you.

    Whilst the 54. Mini isn't supplied with a mounting system, it works perfectly with the Huldit Universal Bike Lock Mount

    The 54 Mini is the little brother to the ultra-secure Granit X Plus 54 (one of ABUS’ flagship D locks). Whilst the 54 Mini’s smaller it packs all the same features and offers increased portability.

    This Mini D lock measures 4.25″ x 5.51″(10.8 x 14cm), which allows plenty of space for your bike and whatever you’re securing it to. The advantage of choosing this lock is that it could be used as a primary bike lock. 

    Used alongside a cable extension you’ll be able to secure all of your bike’s most valuable components with the 54 Mini.

    For a lock of this quality, you’d be right to expect a hefty price tag, but you’d also be wrong. The Granit X Mini 54 is surprisingly one of the more affordable locks in this list and was included in my article reviewing the best D locks.

    If you’re able to overlook those few extra grams, this is the best lightweight bike lock for you. You can view the most competitive price on Amazon here

    TiGr Mini - One of the Lightest Locks on the Market - Titanium & Super Practical

    The majority of bike locks that I recommend tend to be made using hardened steel. Unfortunately for them, steel is super heavy stuff and means most steel-based bike locks didn’t make the cut.

    That’s where the TiGr Mini comes in. This D lock has moved away from the classic steel shackle and has harnessed the power of titanium.

    Now, you may want to take a seat for a moment… the TiGr Mini weighs 1.08lb (0.46kg)! Yes, you read correctly. This is easily the lightest bike lock covered in this review. 

    If you'd rather not use its mount, the TiGr Mini won't take up much space in your backpack.

    Titanium is hard to match for its strength, and what’s more, it’s super lightweight.

    The design team behind the TiGr Mini have produced a lock that offers one of, if not the best security to weight ratios of any bike lock out there.

    Due to its impressive properties, the price for titanium has always been high, but for the protection and practicality that the TiGr Mini boasts, it remains relatively cheap and affordable. A great choice for those wishing for the lightest bike lock (that still offers good levels of security).

    The TiGr Mini is hasn’t been Sold Secure rated, but ART the well known Dutch security rating organisation gave the TiGr Mini 2/5 stars for the security it offers.

    This means the TiGr mini is suitable for securing bicycles according to ART. This 2-star rating is roughly equivalent to a Sold Secure Silver rating.

    When I received the TiGr I was eager to see just how lightweight it was. It’s safe to say, the is the lightest bike lock that I recommend.

    Designed and produced in the USA this is a nifty little lock that will work well for commuters and those constantly on the move.

    TiGr Mini the best lightweight bike lock

    The TiGr Mini is supplied with a simple yet effective mounting system that is also very lightweight.

    It’s also extremely quiet to ride with when mounted to your bike’s frame, which is nice. Unfortunately, it’s not silent like the Foldylock Compact.

    It’s easily the lightest lock in my review of the best lightweight bike locks. But its thinner shackle means it’s not as secure as the Foldylock or the 54 Mini.

    Litelok Silver - Lightweight Sold Secure Silver Security

    LiteLok Silver may be the little brother to the LiteLok Gold, but it performs to the same high standards.

    The LiteLok Silver is a whole new world of bike lock technology, that may appear similar to the LiteLok Gold but has a few different interesting features. When I was deciding on “the best lightweight bike lock”, I had no doubt that the LiteLok Silver would also be making an appearance.

    The LiteLok Silver weighs in at just 1.39lb (630g) this makes it one of the lightest Sold Secure Silver rated bike lock in the world. The LiteLok Silver comes with a standard locking circumference of 20.5″ (52cm), which gives you plenty of room to secure your bike.

    If you are looking for something slightly larger there are two bigger options, the LiteLok Silver 70 and the LiteLok Silver 85. These are slightly less lightweight, but offer a larger locking area and are more suitable for securing multiple bikes.

    These two longer Liteloks allow for more locking space and would enable you to secure more than one bicycle at a time. Alternatively, thanks to the flexibility of the Litelok, you could use either the LiteLok Silver 70 or 85 to further secure the accessories of your bike along with your bike’s frame.

    The LiteLok Silver has a very similar construction to the LiteLok Gold. It makes use of the revolutionary material Boaflexicore within its shackle, it also features a few new additions that all add to the overall security of this incredible bike lock.

    The locking mechanism has been a focal point when it comes to the design of this bike lock. The lock housing is made from hardened aerospace grade stainless steel, which broke 3 different pairs of bolt cutters when tested by LiteLok.

    Litelok vs bolt cutters

    LiteLok Silver also comes in a twin pack. The great thing about the twin pack is that you are able to use one set of keys for both locks. This makes family bike rides much less stressful as you’ll only have one key to look after.

    Another great reason to invest in the LiteLok is that by purchasing two or more of these locks you are able to join them together and by doing so you create a larger locking system that can secure multiple bikes at any one time.

    The LiteLok Silver can be worn around the waist, stored conveniently on your bike frame, or stowed away easily in a rucksack. If you require a bike lock that is super lightweight and provides great security, then you should definitely consider the LiteLok Silver.

    Kryptonitne New-U Evolution Lite Mini-6 - A Lightweight Beast

    Last but not least in my list of the best lightweight bike locks, we have the Kryptonite New-U – Evolution Lite Mini-6.

    It’s of no surprise really that Kryptonite made it into my top 5 lightweight bike locks. They have been producing top-quality locking solutions for over 40 years, I’d be surprised if you were into cycling but hadn’t heard their name.

    The Evolution Lite Mini-6 is a remarkable bike lock for its weight and size. Kryptonite themselves classify this lock as a “High Security” bike lock. Weighing in at a mere 1.6lbs (730g) the Evolution Mini-6 is only 3.5oz (100g) heavier than the Litelok Silver.

    It’s arguable that Mini-6 offers more protection for your bike than the Litelok Silver. Its solid steel shackle is bolt cutter resistant and provides your bike with impressive security level for such a lightweight bike lock. 

    The Mini-6 is quite obviously a mini D lock. Its 11mm shackle is built using “MAX-Performance” steel that is designed to match the strength of Kryptonite’s larger 13mm shackles.

    NEW-U - EVOLUTION LITE MINI-6 Annotated Diagram
    Alongside the MAX-PERFOMANCE steel, the Mini-6 also features Kryptonites infamous double deabolt design.

    The Mini-6 is smaller than most standard D locks and measures just 7 x 15.3cm (2.75 x 6”). As the locking space is considerably small on this D lock, I’d suggest that you check it will work for you and your bike before committing to any purchase!

    Because the shackle of the mini-6 is small, it makes it much easier to carry and less vulnerable to twist and hydraulic attacks! Whilst the Mini-6 doesn’t come with a frame mount, it can easily fit into your rucksack or slide between your belt loops for convenient, quick usage.

    Sold Secure gave the Mini-6 the Silver rating, which makes it suitable for frequent shorter-term lock-ups. This would be suitable for securing your bike in medium-high risk areas for shorter periods of time or would make a great secondary bike lock.

    Kryptonite Security Rating Scale 7/10
    Kryptonite awarded the Evolution Mini-6 7/10 on their in-house rating security rating scale. Not bad for a bike lock that weighs 700 grams!

    Whilst you shouldn’t rely on this as your main bike lock for overnight or long term lock-ups, you’d be hard pushed to find a better alternative for daily usage. You’d also struggle to find a similar quality lightweight D lock for the same price as the Mini-6.

    If you require a lightweight, secure bike lock and prefer the traditional D lock style, the Kryptonite New-U Evolution Mini-6 is the one for you. 

    Which Bike Locks Can Be Considered 'Lightweight'?

    Depending on how strong you are feeling your answer may be different here to mine here.

    To benchmark my best lightweight bike locks, I’ve decided to keep ‘lightweight’ as close to 2.2lb (1kg) as possible. 

    I want your bike to be as secure as this one. Just without the hassle!

    I’ve also included some locks that weigh slightly more, with the hope that you’ll be able to carry the tiny amount of extra weight!

    The slightly heavier bike locks below are aimed towards those who require a higher level of security for their bike. 

    I always attempt to include locks in my reviews that are accessible/affordable to the majority of cyclists. However, I also want your bike to remain as secure as possible whilst locked. Because of this, I will only ever recommend quality bike locks.

    A few of the locks below are relatively expensive, this reflects the engineering and time that’s gone into their design and production.

    Normally the most secure bike locks tend to use heavy metals, so producing a lock which is lightweight, whilst still providing good security is an incredibly tough job.

    Which Bike Locks to Avoid

    As stated above, cheap and cheerful bike locks will almost always end with the disappointment of some sort. You’ll either end up with your lock jamming on you or a thief will simply remove the lock and it won’t just be the lock that you’ll have to replace!

    I don’t stock or recommend anyone to use cable locks, this is because of the poor security that they offer. I also advise all of my readers to purchase a lock with a Sold Secure Silver or Sold Secure Gold Rating.

    If you’re not sure what Sold Secure means, then read the rest of this short article. You’ll then be able to distinguish quality bike locks from the cheap and cheerful ones.

    Bicycle Cable Lock

    Bike thieves never want to hang around for a long time, and they will always go for the weakest looking locks. If you’re browsing the web for a new bike lock and see something that looks cheap and flimsy, it most likely won’t provide the security you need.

    A thief will see that your bicycle is poorly secured and within no time, will have made off with your ride.

    What Factors Would Classify as the "Best" Bike Lock?

    I’d love to be able to tell you exactly which bike lock is the best for you and your needs. Unfortunately, everyone has different requirements and different ideas as to what they’d consider the best.

    The sole point of a bike lock is to keep your bicycle secure, so security is one of my deciding factors when I talk about “the best bike lock”.

    Practicality is definitely something you should also consider when purchasing a bike lock, which is probably why you’re here! A massive chain and lock would not be suitable to carry in your rucksack whilst you commute to work, so I have taken size and design into consideration whilst deciding the best lightweight bike locks.

    We all want a good deal! Invest in a good quality lock, that will properly protect your bike and last a lifetime!

    Finally, price. Ultimately, I want you, my readers to spend the least amount of money possible, whilst still receiving the quality and security needed from your bike lock (I’m sure you do too!).

    You may have already found a few bargains elsewhere, brightly coloured cable locks are super popular, and at under £10, you’d be a fool not to have one, right? 

    The sad truth is these cheap and flimsy bike locks will not protect your ride, and you’ll most likely end up bike-less! You’d be surprised how quickly a small pair of wire cutters can get through cheap and cheerful bike locks.

    Bike Security Ratings Explained

    Sold Secure Ratings

    Bicycle security ratings cause confusion amongst cyclists. With so many different security ratings out there it can be hard to judge how secure a lock is. 

    The most reliable and reputable security rating company is Sold Secure. Sold Secure is a non-profit organisation and was set up by the Master Locksmiths to provide consumers with a way of comparing the quality of different security products. 

    Locks and products that are Sold Secure rated will display one or more of their markings. 

    Bike locks that are tested and pass testing are given one of three ratings. Bronze, Silver or Gold. 

    Sold Secure Ratings 2020

    Bronze Sold Secure is the lowest rating a bike lock can achieve from Sold Secure. As stated on their website Sold Secure Bronze bike locks only provide protection from the opportunist thief. A bike lock that only protects your bike from chancers? AKA a big waste of money! 

    You won’t find Sold Secure Bronze locks recommended anywhere on BikeLockWiki. Avoid them if possible. 

    Sold Secure Silver is the next security rating that bicycle locks can receive. Sold Secure Silver offers a compromise between security and price. Several of the lightweight locks in this article bear the Sold Secure Silver rating.

    Silver rated locks are suitable for less expensive bikes or shorter-term lock-ups. 

    Finally, Sold Secure Gold, The best of the best. Sold Secure Gold bike locks offer the highest level of security. Two of the locks featured in this article bear the gold rating, these are suitable for use in high-risk areas and for locking your bike for longer periods of time. 

    How to Choose the Right Sold Secure Rating

    So now you understand what the different ratings mean, it’s time to choose which one works best for you and your bike. 

    It wouldn’t make sense to spend thousands on your bicycle, only to secure it with a cheap plastic bike lock. 

    The flow diagram below should help you decide which security rating suits you best. 

    A diagram explaining which sold secure rating cyclists require.
    (Click to enlarge)

    The more secure a bike lock, the more it’s likely to cost. Most of the best bike locks come with a lifetime warranty, so bear this in mind when deciding which works best for you.

     

    The Best Lightweight Bike Lock - Summary

    These are the best lightweight bike locks on the market to date. I chose to include a variety of different types of locks, to showcase their strengths and differences.

    If you’re planning on purchasing a bike lock it’s important to take time with your decision and to understand what each lock has to offer. Everyone requires something slightly different to suit their situation, and it’s crucial that you find the right bike lock for you.
