Great security lock - Highly recommended

"Great lock for your e-bike! It’s highly secure and extremely lighter compared to the competition, very user friendly for commutes. I’m very happy with the purchase so far, and still got my e-bike with me: I guess it’s a great deterrent for thieves."

Davide L.

Great Lock

"This is a brilliant, well considered product. The lock is very light for its type and is beautifully constructed. Overall, very happy with the purchase - highly recommended!"

Mehrdad M.

Loved it so much I bought another one

"Bought one of these as had two bikes stolen from work even with a D lock. This feels genuinely more chunky and leaves less space (but enough) on racks to secure. As I live in a high theft zone I then decided to buy another one for a family member as I was so impressed."

Tried & Tested by Independent Experts

Josh Patterson, The Guardian

"The Litelok X1 is the best overall bike lock we tested. It balances real-world grinder resistance with everyday usability and it is relatively low-weight. This makes it ideal for e-bike riders, daily commuters and anyone locking up in theft-prone areas."

Ryan Winiata, wired.com

"Litelok’s trusty X1 offers serious security and impressive versatility for a wide range of users, bikes, and racks. As an angle-grinder-resistant U-lock, the X1’s security scores are among the highest available."

Carl Ellis, thebestbikelock.com

"The best all round bike lock in 2025 is still the Litelok X1. This is because it’s the anti-angle grinder bike lock that provides the best balance between security, practicality and price, for those cyclists that need a higher level of protection."

Jeremy Benson, GearJunkie

"The LITELOK X1 masterfully balances security, price, and performance. In addition to having a slightly larger locking area than most angle grinder-resistant locks, it’s among the lightest and easiest on the wallet."

Mike Stead, road.cc

"The Litelok X1 is one of the lightest Diamond-rated D-locks around. Even more impressive is that for the 1.7kg weight it's a full-size lock with large internal locking dimensions. And it was the cheapest lock to survive our angle grinder test by a long way."

Warren Rossiter, Bike Radar

"The best-value angle-grinder resistant lock we’ve ever tested. When I tried to cut it with an angle grinder, it took 4min 38secs (including disc changes) to cut through one side of the X1’s shackle, which exceeds its premium rivals and the Sold Secure Powered Cycle Diamond rating."

What Makes the World's Best Bike Lock?

LITELOK X1 is the only full-sized armoured D-lock on the market and contains a host of clever design features that make it easy to use and carry so you can keep your bike secure against the most determined bike thieves.

Lock Cylinder

X1 features a high-quality lock cylinder which is durable and pick-resistant. The keyhole is protected from dirt, dust and moisture with our innovative self-sealing silicone keyhole cover.

Reflective Strips

X1 locks are finished with Quartz White retro-reflective vinyl strips along the lock shackle and on the X's at each end. The reflective strips flash in headlights to keep you safe and seen.

Anti-Rotation

Unique anti-rotation feature protects against twisting attacks and single cuts

Easy to Carry

X1 is compatible with our innovative X1 tactical Mount and Twist & Go Mount which means you can attach the lock to your frame with ease. Both mounts are sold separately.

Armed with Barronium®

Barronium® fused composite armour repels angle grinder attacks and eats angle grinder discs.

LITELOK X1

Tested to Destruction

Tested against the best-selling D-locks on the market, LITELOK X1 is at least 5 times more resistant to angle grinder cuts. Additionally, X1 requires multiple discs to cut and due to its anti-rotation system, needs to be cut on both sides to remove.

LITELOK X1

Barronium®

Barronium® is a fused composite armour that offers unparalleled angle grinder resistance without adding extra weight. It is a super hard ceramic composite material that repels angle grinder attacks and turns the grinder's energy and force in on itself. Continuous cutting wears down the grinder discs, batteries and ultimately the grinder motor itself.

    LITELOK X1 MOTO
    Rated 4 out of 5 stars
    Amazing lock, now just make one that fits motorbikes!

    Let's get the elephant in the room out of the way - this was not designed for motorbikes, and it only fits on some motorcycle wheels, so make sure you've used the template available on the website and ensure it will fit on your bike before buying... Probably great for a little 125 or something of that nature, but won't work on a larger bike in general unless you have the kind of hubs it can go through.

    SO that's the only reason this isn't a 5-star review

    That aside, it is lightweight, really solid build quality, extremely portable, and does everything I need it to do on one of my bike's front wheels, at least.

    Not tested it myself or yet had some thieving little scrote try doing it on my behalf, but I feel a lot better knowing I have it when I'm out and about on my little Himalayan, and wouldn't want to be without it.

    LITELOK X1 MOTO
    Rated 5 out of 5 stars
    Looks and feel solid secure and dependable

    I bought this Litelok X1 Moto for my new motorbike, and guess what? It has given me the peace and security I was looking for when it comes to securing my bike. Okay, it's not ballistic attack approved, but when it comes to someone thinking of stealing my bike, they will certainly have to put in more effort than I put into buying this lock. Great job, Litelok! Keep up the good work! 👏

    LITELOK X1
    Rated 5 out of 5 stars
    Great lock - looks good and gives real peace of mind

    I’m genuinely impressed with the X1 bicycle lock. From the moment I took it out of the box, it stood out with its sleek, high‑quality look, but what really matters is the peace of mind it brings. I can confidently leave my bike locked in public spaces, knowing the lock is solid and dependable and will truly do its job. It feels like a well‑thought‑out product that balances design and security perfectly. Overall, it’s a great investment and one I’d happily recommend to any cyclist who values both style and reliable protection for their bike.

    LITELOK X1
    Rated 5 out of 5 stars
    First bike and first lock.

    This is my first motorcycle lock, and after doing quite a bit of research I decided to go with the Litelok X1 — and I’m really glad I did.

    Right out of the box the lock feels incredibly solid and well made. The build quality is excellent and it immediately gives you confidence that it’s designed to deal with serious theft attempts. One of the main reasons I chose the X1 was its reputation for being highly resistant to angle grinder attacks, which gave me a lot more peace of mind compared to cheaper locks.

    One thing that did surprise me at first is that it’s a bit smaller than I originally expected. My initial plan was to use it mainly to lock the bike to something solid, like a ground anchor or street furniture. Because of the size that’s not always possible depending on what you're locking to, but it actually works really well when I put it through the spokes of my motorcycle wheel instead. It still feels extremely secure and is very quick and easy to use that way.

    Another thing I really like is how lightweight it is for such a strong lock. It doesn’t feel like a burden to carry around, which makes it much more practical for everyday use. It also comes with a small carry pouch, which is really useful for transporting it—especially if the lock gets dirty from being in and around the spokes.

    The locking mechanism feels smooth and reliable, and it clicks shut securely every time. As someone buying their first motorcycle security, I wanted something that would give me real…

    Rated 5 out of 5 stars
    Gives me peace of mind to actually use my bike

    As an anxious person it would be easy to psych myself out of ever using my bike properly because I live in a city where bicycle theft is rife.

    The X1 gives me the confidence to leave my bike locked up in public without spending the rest of the day fretting. Money well spent.

    LITELOK X1 MOTO
    Rated 5 out of 5 stars
    The best bang for your buck!

    No longer having secure parking and having to park my bike in the driveway, I was very apprehensive to say the least about moving home. I had the normal sold secure chains and locks but they were cumbersome and I have seen so many videos online where thieve's with angle grinders have still cut through them relatively easily. After being in my new home for a month, sleeping with the window open in the middle of winter, just in case I would be woken up by someone trying to steal my motorbike...I'd had enough. I'd seen some ads for litelock on social media and decided to look into them in more detail and having seen people, even in other countries recommend them...I just went out and bought the X1 hoping it was a worthy investment to try introduce some calm into what has now become a regular activity of checking my bike multiple times a night. I'm so pleased that I bought it and now will be buying a second so I can have one on each wheel and get rid of the awkward heavy chains and locks I currently use on the other wheel. Extremely good quality, easy to put on and a major deterrent to any potential thieves.. it will certainly give me time to react should someone attempt to cut through it. 100% recommended.
