Great Lock

Lock exceeds expectations. Fits a fat tire e-bike easily. Very sturdy! Punches way above it's weight class price wise.

Mark P.

Heavy Duty

Love this thing. Heavy duty and gives me piece of mind when locking it up outside. It also comes with a pouch I use before storing it in my pannier bag.

Best security to weight ratio hands down

These locks are legitimately impressive. Best security to weight ratio I could find. Happy with the quick shipping and size and performance so far.

What the experts say...

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."

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."

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."

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 (both sold separately) mount which means you can attach the lock to your frame with ease.

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.

    Brilliant lock

    Easy to use, smooth, clips together easily, key isn’t stiff ever. And I love how the key entrance is protected from the rain etc, to prevent rusting.

    Preiswertes Schloss

    Ich habe das Litelok X1 für mein E-Bike gekauft, da ich etwas brauchte, das mein Fahrrad auch während der Nachtschicht vor der Klinik, in der ich arbeite, sicher hält. Für den Preis von knapp 180€ ist es das günstigste Schloss in seiner Kategorie und es wirkt extrem stabil. Mir ist es schon das ein oder andere Mal heruntergeladen, aber es sieht noch aus wie neu, nur etwas dreckig. Der Schließmechanismus funktioniert einfach ohne Probleme. Mein einziges Manko an diesem Schloss ist, dass es an einigen Fahrradständern zu kurz ist, um Sowohl Rahmen als auch das hintere Rad zu sichern. Ich denke dahingehend ist das X1 Plus besser, wobei dann der Preis auch wieder ein anderer ist... Da ich ein sekundäres Schloss verwende, um die Räder am Rahmen zu sichern, reicht es mir aber mit dem X1 "nur" den Rahmen zu sichern.

    Niiiiiiice lock!!!

    I got the camo one, couldn’t find it at first… ;)

    Lock is solid, nice touch to have the keyhole covered. Hopefully it will never be tested but I do have faith in it, especially when the bike has value, madness to think my last lock was a tenner!! This is a serious upgrade and It looks great. A fair few people at work have had a look and been very impressed!

    Lighter than it looks, and genuinely reassuring

    Bought this a few weeks ago to secure my e-bike and honestly it's better than I expected. It's noticeably lighter than it has any right to be given how solid it feels, and it's straightforward to use once you get the hang of the angle. Gives me real peace of mind leaving a £2,300 bike locked up. Worth every penny.

    Great lock with a few caveats!

    This lock is the perfect amount of security for my use case. I work at a college campus and must lock my bike outside. It fits around the wheel and frame of my standard hybrid bike when locking to most posts, as long as the post isn't really thick. It will fit around the frame of my folding bike, but cannot lock the frame and wheel at the same time due to the length, so for that, I usually fold my bike in on itself before locking (no photo because it's as one would expect). Sometimes I just use it to lock the front wheel when I'm really in a rush in the mornings and use a lock from another brand that's long enough to go through the back wheel + frame (see photo). But I really like this lock, and it's held up for the past seven or eight months, as shown by the video. Kinda heavy when compared with a second lock, but that's fine given the context.

    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.

    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…
