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...

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 (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.

    I haven't seen better.

    This is my third lock - it gives me piece of mind that my bikes are tucked up with my locks at night and when I park up in town, the scroats will see these and go elsewhere.

    LITELOK equals peace of mind.

    Whether my bike is at home in my garage. I’ve stopped locally for an extended period, or have gone a multi day road trip the LITELOK X1 is my go to motorcycle & bicycle lock. Its rugged anti grinder construction will definitely give the baddies a problem. I know that if a bad guy wants it bad enough he will likely get it. But I want to make it as difficult as possible for him. So I take the X1 wherever my motorcycle goes.

    A lock that's worth it.

    In anticipation of a new job change, I am looking forward to commuting by bike to my workplace! However, I started to have anxiety about thieves who would be looking at my gravel/commuting bike. I've had theft scares in the past, and my previous setup included a cheaper u-lock with a cable. I wanted to upgrade my locking system, and this u-lock is the right answer. Yes, it is expensive, but I think what you're buying is peace of mind for the anti-angle grinder resistance, as well as a sturdy, lightweight, beautiful product that simply works well. I haven't started my new job yet, so I haven't gotten the chance to commute with it yet, but like I said, what I'm really buying is peace of mind. Sorry for the awkward camera angles in my video!

    Awesome Lock but ....

    I wished the shackle was a bit longer. It would be nice if Litelok offered a longer version.

    Awesome lock!

    This lock looks, feels and, going by videos and reviews, is the business. I feel confident leaving my bike whilst I go shopping in Hull city centre and I’m now eyeing up additional Litelok products to secure both wheels of my bike for ultimate protection. Well done Litelok!
