What the experts say...

James Grear, bikelockwiki.com

"If you don't fancy becoming another victim on the police bike theft database, there isn't a better lock for you than the X1."

Carl Ellis, thebestbikelock.com

"It’s definitely the most secure bike lock I’ve ever tested. And that it manages this without being excessively heavy, bulky, massively expensive or incredibly unpractical, is indeed a BIG DEAL!"

Warren Rossiter, Bike Radar

"...armoured with a composite material called Barronium®, resisted the attack of our angle grinder for more than 17 minutes, That's almost three times longer than the previous toughest lock we've tested."

Josh Ross, Cycling News

"Litelok doesn't claim the X1 is angle grinder proof, and it's not, but it takes two cuts to free a bike and a single but will trash a grinder disc. That's enough security for most bikes in most situations and it comes without tradeoffs in price and useability."

Rob Clymo, T3

"A quality lock such as this one is a huge hurdle for cycle thieves and could well put them off having a go altogether. In that respect, the Litelok X1 seems like a bit of a bargain, especially if your ride has cost you thhousands to buy in the first place."

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 comes with our innovative Twist & Go 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.

LITELOK X1

Twist & Go Mount

LITELOK X1 is sold with an innovative Twist & Go mount that fits almost any bike style, firmly holding X1 in place on the bumpiest of roads while remaining quick to both affix and remove.

LITELOK X1

Restrap

We collaborated with Restrap to create a co-branded belt holster, which provides an additional carrying option if you don't want to mount X1 to your bike.

  • 2 x Unique Keys

    I pity the fool!

    The price turned me off at first, thinking a cheaper one would protect my new e-bike well enough. After only a few weeks using the X1, this (see photo) is the proof I needed to see its value. Another lock would have probably been cut through by the nasty fellow (in broad daylight).

    The only downside of still having my ebike, is that I might have to buy a replacement X1 this soon :(.

    Thank you for the save, Litelok.

    Close to perfect

    The good: Tough looking, tough feeling U-lock. Shipped fast with tracking to the USA. Key operation is smooth easy. Only one of a few angle grinder resistant locks. Key replacement/registration. Nice rubber shell and silicon keyhole protector. Highly rated by everyone!

    The bad: The reflective tape on the X1 bike lock just comes right off with the slightest rub. Why not use reflective paint instead? Litelok really just seemed to add this as an afterthought without any kind of testing?

    Other thiughts: This lock is expensive. Is having that little bit of extra angle grinder resistance worth an extra 150 bucks? Like insurance, it's never worth it until it's worth it. So that answer is definitely debatable depending on your philosophy on the matter. The Twist on Mount seems to be pretty good if you use it in the way it was meant to be used. However on an e-scooter like I have I had to adapt to the way I mounted the lock with the twist Lock Mount. See the picture. It would be great if lightlock offered a mount designed for e-scooters.

    Locking my Brompton!

    I only occasionally lock my Brompton - when I have no other choice. My Litelok let's me do so with a lot less worry.

    Very easy to use, feels like quality design and make.

    So far very pleased.

    The best D lock ever

    The lock fits perfectly on my little electric bike. I thought I wouldn’t be able to mount it on the frame… but where there’s a will there’s a way! Feel completely confident that my bike won’t get taken with this bad boy protecting it. Only thing I would say is it’s a little heavy.. but hey! If it angle grinder safe, that’s to be expected. Completely happy customer

    My new Bike Lock

    It very good I do like the case it comes with and the holder for it but I have a E-Bike and no where to put it as I have a rack on the back the battery takes up the space where I would put it normally but that's great I keep it in my pannier bag.

    I use it with my Oxford gold lock with an alarm so the deterrent of the alarm helps.

    Ein sehr gutes Schloss

    Das Schloss ist hervorragend, es ist leicht und hält was es verspricht.

    Über eine kleine Anleitung, wie man die Halterung installiert wäre für mich sehr hilfreich gewesen, bis heute habe ich die Halterung nicht installieren können.

    Dennoch ist das Fahrradschloss ein muss.

    We love this

    Having had two e-bikes stolen security for our new ones was very important. What a relief to find LITELOK. Excellent service and I can’t see those pesky thieves getting through this time. Solid build that says ‘stay away’.

    The perfect lock I was waiting for

    Great lock, one of two sold secure diamond status locks, the other one (Hiplock) is much more expensive and 200 g heavier. A highly appreciated surprise was the neoprene bag for comfortable transport in my backpack. I use my new Litelok X1 on my high end fixed gear bikes and it is just as plain, simple and strong, parallel to my “old” Abus chain lock (security level 12/15), depends on where I’m parking.
