LITELOK: Is this a game changer for bicycle security?

Last Updated on September 6, 2022 30 Comments

Update (April 30th 2017):

I’ve now got hold of a LITELOK and have been using it for the past month. Check out my full hands-on LITELOK review here.

Litelock Flexible Lightweight Bike Lock

Sometimes it seems like barely a week passes by without the launch of another Kickstarter funded bike lock from yet another trendy startup company.

And the promise is always the same: we will solve all your bicycle security problems with our clever ideas and the latest cutting edge technology.

There’s always a slick video. There’s usually a smart phone app. And more often than not, I’m left slightly baffled and a little bit disappointed.

Why? Because they either solve problems that don’t seem that significant. Or add layers of technological complexity that will inevitably unravel in the real world. Sometimes they manage to achieve both of these things.

And they always seem to marginalize the most important part of any lock: the security. In most of these projects the security level of the lock almost feels like an afterthought. When it should be the very highest priority.

Because lets face it, a bike lock must protect your bike from theft. If the lock is defeated and your bike is stolen, no amount of innovative design features will save it from being utterly, utterly useless.

And of course, we all know that along with security comes weight. The two are inextricably linked. The more secure a bike lock is, the heavier it is. It’s unavoidable. And this is one of the greatest problems with bike security: in order to adequately protect your bike, you have to lug round a very weighty and very inconvenient bit of metal.

So when I first read about the LITELOK, I was understandably dubious. A light bike lock that is also secure? It’s impossible. Isn’t it?

Litelock Flexible Lightweight Bike Lock

Well, apparently not. Using a new, super tough, super light material they call “Boaflexicore”, the LITELOK defies expectations. Not only does it weigh less than 1 Kg, it’s also been awarded the very highest Gold security rating from Sold Secure, the independent lock testers.

How does it compare to other locks? At first glance it seems to offer all the advantages and none of the disadvantages of it’s competitors…

The LITELOK is closest in form and function to cable or chain locks. These are practical and easy to use. But most cable locks are close to useless when it comes to actually protecting your bike and chain locks are notoriously heavy. And while the other major alternative U-locks, can provide a high level of protection at a reasonable weight, their rigid shape means they’re not always so practical to use.

Sounds promising! But let’s look at some real world comparisons. You can compare the weights of security ratings of a whole load of U-locks here and chain locks here.

Compared to chains, both the Kryptonite Keeper 755 Mini and the Hiplok Lite are about the same length and weight as the LITELOK. But both of these locks only have a Sold Secure Bronze security rating. And there’s a big, big difference between Bronze and Gold. In fact, I don’t recommend locks that are rated Sold Secure Bronze to anyone.

And the lightest chain lock that offers a Sold Secure Gold rating is the Abus CityChain 1010 85 which is twice as heavy as the LITELOK. (It’s also slightly longer, but only by 4 inches.)

Talking of length, the LITELOK is admittedly, not very long. In fact at 29″ / 73.6 cm, it’s pretty short. But you can actually join two of them together to double the usable length if you really need to.

Against U-locks, which are generally lighter, you might think the competition would be closer. But the lightest Sold Secure Gold rated U-lock I can find (with a verified weight) is the Abus U-mini 401 Yellow. Not only is it still slightly heavier than the LITELOK, it’s also a mini u-lock which makes it significantly less practical to use.

So yes, it does seem like the LITELOK may well have found that hallowed ground where a high degree of practicality is not undermined by poor security.

But this isn’t a proper review. Let’s save a full appraisal of the LITELOK until it’s been released and real people start using it in the real world. When real thieves start to tackle it with real tools. Because a Sold Secure rating is not the be all and end all. Let’s see how the thieves rate it.

However I am genuinely optimistic, even excited by the prospects of this lock. The people behind it seem to have done everything right so far. They’ve tackled a genuine problem. They’ve had their lock certified by an independent tester. And there’s no smart phone app in sight!

So I really look forward to giving it a full review once it is released. In the meantime, if you need great lock RIGHT NOW, check out my guide on how to choose a lock.

I've had bikes stolen in London, New York and Barcelona. Yep, I was a serial, international, bike theft victim. In 2015 I decided to stop the rot. And not a single bike's been stolen since! Brakes, yes. Bells, yes. But they're another story. Everything I learn, I document on this website. More about my story. Contact me. LinkedIn.

  • I’m still waiting to receive my litelok after ordering it almost 3 months ago. Ok it was a pre order but I would like to have an answer when I will get mine now that it is in production.
    I hope that it will be a good lock that was worth waiting for.


  • I got my Litelok a few days ago. I’m disappointed by the follwing issues, ordered by priority:
    1) The key does not work smoothly (neither of the 3 keys). Sometimes the key blocks halfway either while inserting or while turning it. This feels like “made in China” and not like a high qualitiy lock mechanism. That’s very annoying because I don’t want to lose my time while fiddling with the key.
    2) It requires both hands and a bit muscle power when connecting both ends with each other. You can’t them simply stick together like an U-lock because you have to *bend* the Litelok strap which is quite rigid.
    3) The coating is already dammaged after only a few usages. Some filaments come out and make loops. That’s ugly and may get entangled in sth.
    4) It seems that the Litelok becomes easily dirty. There are already some visible dark (grease?) spots on the boa green Litelok.
    5) The transport straps are ridiculous. It takes much more time to attach the Litelok with these straps than to snap in an U-lock into its plastic holder.
    6) Litelok is bulkier than an U-lock.

    • Oh no, that’s disappointing Mike!

      I did wonder about what sort of cosmetic condition it would be in after a few months on the streets.

      And if the key doesn’t work well and it’s more impractical than a u-lock, that’s not very good at all.

    • agreed on every point – I am sure they are well intentioned but it’s become a PR exercise of “we all love our friend Litelok” to sell them before the truth gets out.

    • I just thought I’d comment here because Mike seems to have had many of the same experiences as myself.

      1) I have had no problems with the key. Mine is only one week old, but very fluid and solid key mechanism.

      2) Yes, it does require both hands to lock/unlock it, and usually even your knee or a post in order to provide enough pressure to make it straight enough for the bolt to slide in/out of the box. This is slightly annoying, to be honest.

      3-4) No comment because mine is still relatively new and has not become frayed or dirty.

      5) Yes, attaching to the frame is surprisingly time consuming. You have to sort of wedge it into the triangle, and then fasten three velcro straps. Probably the best thing litelock could do to improve this product would be to work on carrying options.

      6) Yes, quite bulky no matter how you deal with it. Definitely light, but quite bulky.

      Again, the compromise here is between bulk and weight. You sacrifice all the ease that comes with rigidity of a d-lock for something that always has constant pressure (when in a circle), or is giant (when stretched out).

      Again, I want to emphasize that – for me – aside from the fraying issue (which has not happened to me yet), all of these issues are small compromises compared to the significant weight reduction.

    • Total cost to me to purchase/ship to the DC area was £100, which in August, 2016 was about $130 USD. The shipping itself is £15, and the product is £85.

  • got my litelock Twin lock Herringbone set. I think they are easy to open and close and using the key is easy to lock or open the litelock. They are flexible enough to allow me to lock around the odd shaped fixed objects that a U-lock make impossible. Good job Litelock!

  • Hi,
    LOL, try to cut the main LOCK mechanism (black pieces) of this lock with bolt cutter!!!!!! There is no Alarm, 21 century locks should have alarm to the phone!!

  • I have been using a litelock for one week for daily commuting. Total cost with shipping to US: ~$125 depending on exact exchange rate.

    Before I begin, I will say that this is my favorite bike lock that I’ve ever used, but there are several things that I see as potentially important for people to be aware of when considering this product vs. others. We all know that no one truly likes bike locks (except, perhaps, Carl, etc. who run this blog – and thank you for that!), and the better they are at their jobs, the more annoying they are. The litelock is really not an exception to this rule, but the trade-offs are somewhat different than the typical trade-offs between weight and security. Here the major trade-off is that it is bulky.

    The difference in weight between this lock and a New York D-lock is noticeable to me even on short (2-3 mile) commutes. No question – it’s light.

    The litelock website shows the lock clipped to the top bar of a bike lengthwise. My 54 cm Trek commuter is too short for this – the ends of the lock hang off and interfere with the tires, wires, and turning. It can fit (in a circle-shaped lock position) in the front triangle, but it must be wedged in there fairly tightly and makes accessing the water bottle difficult. It takes more room in a backpack than a d-lock, and really has to go in the main compartment of a bag. It is not very flexible, and there is no way to make it small for transport.

    The main issue with the bulk is that it is wide and therefore cannot loop through the rear tire without applying constant pressure on at least two spokes, and my guess is that this will cause the spokes to bend over time. So I lock my back tire with a cable, just like front one, and use the litelock just on the frame. If you had nicer wheels with fewer spokes, this would not be a problem.

    It is big enough to lock around many things that a d-lock cannot. I would not call it “flexible” though. Lock mechanism is, so far, fluid and solid – some amount of pressure is needed during locking and unlocking in order to make it “straight” so that the bolt can slide into the box.

    If you are going to be carrying around a lock all the time, then this one wins on weight, but compromises on bulkiness. If you are going to put it in a backpack, it’s great. If you want to clip it to a frame, it has the advantage of not having any chance of moving during riding (like d-locks sometimes do), but takes up a lot of space on the frame no matter how you do it.

    • Great detailed review! Thanks so much for this Earl.

      I wonder if they’ve thought about doing a “mini” Litelok, in the same way that TiGr have done a mini Titanium lock. So this would be just long enough to fasten the frame, or the seat tube and the back wheel to a bike stand. It would be considerably less bulky. But I suppose reduced flexibility might be an issue.

  • Sounds like a decent option but the bulk is hard for me to consider it. I carry around a D lock and a cable for the wheels and while it’s a little heavy it works. I’d be more interested in a slightly less secure but smaller, more flexible version of this product. Maybe wouldn’t be “gold” security standard but good enough for short-stay stops in fairly safe areas which where I tend to be.

  • Hi,

    just received my Litelock, and if I am rather happy with the product, I am very surprised at the simplicity of the lock mechanism (and the keys delivered).

    IMHO, any decent “key picker” could just open that lock with a simple picking tool. I don’t have that skill, but really the keys (and the lock mechanism that I can see inside) are of the simplest form !

    As Sam mentionned, I am curious too to see someone trying to cut through the black plastic pieces to see if it was secured.

    A lock will only be as tough as it’s weakest part… so I hope Litelock will quickly act upon our requests here or their marketing efforts may quickly be ridiculed by a “how to force a litelock” video.

    • Interesting points Nicolo, thanks!

      I would presume that Sold Secure would have tested both the mechanism and the black pieces. And that if they’d been found wanting, the lock wouldn’t have received a Gold rating.

      How are you finding it in terms of usability? This is where a lot of other people seem a bit disappointed.


  • Ermmm on the photo of you locking the bike up if somebody unscrewed the wheel the could pull it straight out, lock it up to a different part of the frame

    • Pfff good find Max. That’s a bit worrying to say the least!

      Leverage attacks like this are really common and many u-locks can be defeated in the same way. But what’s surprising and worrying in this case is that the Litelok was defeated by such a short length of metal.

      With a good u-lock a thief would usually need to use a much longer length of metal. A piece of scaffolding for instance.

      It looks like he was using the handle of a hammer here!

  • After purchasing and using the lock here are one person’s real life experiences…

    The lock section is too bulky to fit through the shackle of a standard bolt-down anchor.
    It is much too short and too stiff to fit around most posts, trees and fence sections.
    Where a Sheffield stand already has a bike secured to one side, the short length, stiffness and necessity to align the two sections of the lock make it very difficult to use the LiteLok without causing damage to either one of the bikes.
    My girlfriend is not strong enough to get the two parts of the lock in line to lock it, without having something to push against at the back of the band. This means that it is impossible to clip it together without damaging either her bike or her clothing
    The LiteLok’s main band is too inflexible to twist, too wide and too short to allow it to pass around a stand, the bike frame and through a wheel without risking damage to the rim or spokes.
    Sadly, the LiteLok is the same weight as her D-lock (When I bought this expensive present – twice the price of a Gold U-Lock) I had expected it to be significantly lighter).
    It won’t store on the bike because it is 20 cm (8 inches) longer than her top tube so interferes with steering.
    It is very bulky: if she puts it in her backpack to carry, it takes up pretty much the entire space. If she shops, she has to take everything out when she gets back to her bike, stow the LiteLok, then repack the shopping inside and around it. She cannot do this in the rain, without everything getting wet.

    Despite asking, the makers don’t give any refund if the lock has been used…

    • Hi Jeremy,

      I’ve also reviewed the Litelok in real life.

      While I agree, it can be a bit stiff and difficult to maneuver to start with, I got used to it pretty quickly and didn’t have too many problems securing my bike (although I didn’t use it in many super busy bike stands). I definitely found it gave me more options than a mini u-lock.

      And regarding it’s weight, the only Gold rated u-locks I could find that were lighter than the Litelok were mini u-locks. What lock is your girlfriend using?

      I totally agree, it’s very bulky in a bag. But although it was slightly longer than my top tube too, it didn’t interfere with my steering. Have you tried attaching it to her frame while it’s locked in a circle? Again, that worked quite well for me (although I preferred it along the top tube).

      I definitely appreciate that the Litelok isn’t for everyone. And the idea of my website is that I explore the sort of usability issues you’ve had with the Litelok.

      So I’m really sorry that you’ve had these problems and can’t return the lock.


  • The Lock picking lawyer I believe found that the band is really just 6 parallel cables with a thin nylon sheath, and a modest cable or bolt cutter chews through in just 6X the time to cut one. The secret is just to determine how strong the weakest link is in any system, and rate accordingly. There could or should be some way to combine materials that resist cutters in different ways, i.e. add a thick kevlar tube around U-locks or chains to tangle up any spinning wheel cutter, and get pressed flat without shearing, etc. A hollow core U-lock with kevlar middle might achieve the same cut resistance.
    It’s a novel start but needs maturation and hardening for the rating to be valid.
