D-lock comparison

LITELOK X1 vs X3: which D-lock do you need?

Every LITELOK D-lock carries Sold Secure Pedal Cycle Diamond, so the question is not whether it is secure enough. It is how much reach and armour you want to carry. X1 is the all-rounder at 1.7kg. X1 MINI saves 220g for short stops. X1 PLUS adds 58mm of reach. X3 is the most resistant lock we make.

Every LITELOK D-lock carries Sold Secure Powered Cycle Diamond and ART4, so the question is reach and armour. X1 Moto is the all-rounder. X1 PLUS Moto reaches a ground anchor as well as the wheel. X3 Moto is at least 20 times more resistant to grinder attacks than the best-selling, unarmoured D-locks.

Side by side

Every specification, compared

All four locks are built the same way: a fine-grain, hardened high-tensile steel core, Barronium® armour permanently fused to it, and a plant-based eco-rubber outer layer. What changes between them is reach, armour and weight.

Swipe the table to see every lock

Security claims are measured against the best-selling, unarmoured D-locks. No lock is angle grinder proof — these are built to resist for long enough to make the attempt not worth it.

Ratings, translated

What the ratings actually mean

Every lock on this page holds Sold Secure Pedal Cycle Diamond, the highest rating awarded to a bicycle lock. That is the floor, not the ceiling — what separates these four is how long they hold up under a grinder.

Every lock on this page holds Sold Secure Powered Cycle Diamond and ART4 — the ratings insurers ask about by name. That is the floor, not the ceiling. What separates these four is how long they hold up under a grinder.

4:38 Independent cut time, X1
ART4 On every lock
  • Sold Secure Diamond

    The highest tier Sold Secure awards, tested by attack rather than by specification. Bikes are rated Pedal Cycle Diamond; motorcycles, scooters and e-bikes are rated Powered Cycle Diamond. Every lock on this page holds both.

  • ART4

    The Dutch attack-testing standard, recognised across Europe and asked for by name on a lot of motorcycle policies. All four locks are ART4 rated — worth quoting to your insurer when you renew.

  • 5× and 20×, explained

    The X1 family resists grinder attack at least 5 times longer than the best-selling, unarmoured D-locks. X3 is at least 20 times — enough that it needs multiple discs and multiple batteries. A thief working in public is counting minutes, and every disc change is another one.

  • Barronium®

    Our own composite armour, permanently fused to a fine-grain, hardened high-tensile steel core, then wrapped in a plant-based eco-rubber outer that will not mark your frame. Made in Britain, in our solar-powered factory in Swansea.

  • Two cuts, not one

    Every lock here resists being twisted out after a single cut, so an attacker has to get through the armour twice. It is the difference between a lock that fails all at once and one that keeps holding.

  • ABLOY® SENTRY on X3

    X3 uses the ABLOY® SENTRY cylinder, among the most pick-resistant mechanisms available. The X1 family uses our own pick-resistant cylinder with a self-sealing silicone keyhole cover to keep the weather out.

No lock is angle grinder proof, and we will never claim otherwise. Resistance claims are measured against the best-selling, unarmoured D-locks.

The honest version

Which one is actually for you

Every lock here is worth owning. They are not all worth owning by you — so here is who each one is built for, and who should buy something else.

LITELOK X1 MINI LITELOK X1 MINI Moto

Our lightest grinder resistant D-Lock

For the rider whose lock spends more time on the bike than around it. At 1.48kg it is 220g lighter than X1, and the 99.5 × 137mm opening is sized for a frame tube and a stand — coffee stops, the school run, an hour outside the shops. It also makes an excellent second lock alongside a bigger one.

Built for scooters and mopeds, and for disc-and-caliper locking where a full-size opening is wasted. At 1.48kg it goes under the seat without an argument, and it still carries Sold Secure Powered Cycle Diamond and ART4.

Look elsewhere if: you leave the bike on the street overnight, or you need to reach a wheel and a stand together. you park on the street overnight, or you need to reach a ground anchor.

LITELOK X1 LITELOK X1 Moto

Best Bike Lock in the World

The default answer for most riders, and the lock we sell most of. 1.7kg, a 101 × 197mm opening that clears a frame tube and a stand comfortably, and at least 5 times more resistance to grinder attacks than the best-selling, unarmoured D-locks. If you are commuting daily on a bike or e-bike and bringing it in at night, this is the one.

The everyday choice for commuters, naked bikes and scooters. 1.7kg, Sold Secure Powered Cycle Diamond and ART4, and light enough that you will actually take it with you rather than leave it in the garage — which is the only place a lock is genuinely useless.

Look elsewhere if: you need to lock frame and wheel to the stand in one pass — that is X1 PLUS. you have a wide rear tyre or a ground anchor to reach — that is X1 PLUS Moto.

LITELOK X1 PLUS LITELOK X1 PLUS Moto

The World's only long-reach grinder resistant D-Lock

The same armour as X1 with 58mm more reach — a 101 × 255mm opening. That is the difference between locking the frame to the stand and locking the frame, the wheel and the stand together, which is the single most useful upgrade on this page for anyone with a cargo bike, a fat-tyre e-bike, or a habit of parking next to awkward street furniture.

The reach lock. 101 × 255mm gets you around the wheel and onto a ground anchor, a lamp post or a railing in one pass, which is exactly the problem most riders are trying to solve. Same Barronium® armour as X1 Moto, 1.99kg.

Look elsewhere if: you are counting every gram — X1 or X1 MINI weigh less. the bike lives on the street overnight in a high-theft area — consider X3 Moto.

LITELOK X3 LITELOK X3 Moto

At least 20× more resistant

The most resistant lock we make, and the answer when the bike is left where you cannot see it for a long time. At least 20 times the grinder resistance of the best-selling, unarmoured D-locks, needing multiple discs and multiple batteries, with an ABLOY® SENTRY cylinder and a 7-year warranty. 2.1kg — 400g more than X1, for a step change in how long it holds.

For on-street and overnight parking, and for bikes that attract attention. At least 20 times the grinder resistance of the best-selling, unarmoured D-locks — multiple discs, multiple batteries, and a very public amount of time and noise. ABLOY® SENTRY cylinder, 7-year warranty, 2.1kg.

Look elsewhere if: you want Key Match across several locks — that is available on the X1 family, not X3. you need maximum reach — X1 PLUS Moto has a 255mm opening against X3's 195mm.

Asked constantly

X1 and X1 Moto are the same lock

Same steel core, same Barronium® armour, same cylinder, same protection. The Moto listings exist because riders and cyclists look for different things, not because the locks are different. The same is true of X1 MINI Moto, X1 PLUS Moto and X3 Moto.

Carrying it

Which mount fits which lock

A lock you leave at home protects nothing. Mounts are sold separately, and they are not interchangeable — check the pairing before you order.

Most riders carry the lock on the bike rather than in a bag. Mounts are sold separately and are not interchangeable — check the pairing before you order.

Before you decide

The questions we get asked most

Is the X3 worth the extra over the X1?

It depends where the bike sleeps. X3 is at least 20 times more resistant to grinder attacks than the best-selling, unarmoured D-locks against the X1 family's 5 times, and it adds the ABLOY® SENTRY cylinder and a 7-year warranty for 400g more weight. If it is parked on the street or left for hours where you cannot see it, yes. If you are carrying it all day for short stops, the X1 is the better lock for you.

What is the difference between X1 and X1 Moto?

Nothing. They are the same lock with the same construction, dimensions, ratings and warranty. We list them separately because riders and cyclists search for different things. The same applies to X1 MINI Moto, X1 PLUS Moto and X3 Moto.

Are these locks angle grinder proof?

No, and we will never say they are. No lock is. What we can tell you is how long they resist: the X1 family holds out at least 5 times longer than the best-selling, unarmoured D-locks, and X3 at least 20 times, needing multiple discs and multiple batteries. Theft in public is a race against time and attention, and that is the race these locks are built to win.

Will it fit around my rear tyre?

Every opening here is around 100mm wide, so a wide rear tyre will not always take a full wrap. On bigger bikes, go through the front wheel and disc, or lock to a ground anchor — X1 PLUS Moto has the reach for it at 101 × 255mm. Tell us what you ride and we will give you a straight answer before you order.

Will this lock reduce my insurance premium?

Some insurers offer a discount for an approved lock, and many ask for Sold Secure or ART ratings by name. Every lock on this page holds Sold Secure Powered Cycle Diamond and ART4. Quote both to your insurer at renewal — riders tell us it has made a difference to their premium.

How do I carry it on the bike?

With a mount, sold separately. X1 MINI takes the X1 MINI Tactical Mount; X1 and X1 PLUS share the X1 Tactical Mount; X3 needs the X3 Tactical Mount. The Twist & Go Mount is a quick-release option across the X1 family. See the mount table above for the full pairing.

Can I have the same key for two locks?

Two ways. Key Match is for when you already own a lock and want your next one keyed to it — available on X1, X1 PLUS and X1 MINI. Keyed Alike is for buying two locks together with matching keys. Neither is available on X3, which uses the ABLOY® SENTRY cylinder.

What if I lose my keys?

Register your keys when the lock arrives and we can supply replacements. It takes a minute and it saves a great deal of trouble later — do it the day it turns up rather than the day you need it.

Why buy direct rather than from a marketplace?

We only sell direct, so litelok.com is the only place to get a genuine lock with the full warranty — 7 years on X3, 3 years on the X1 family — along with key registration, Key Match and our own support team. Anything listed elsewhere is outside that.

Where are they made?

Made in Britain, in our own solar-powered factory in Swansea. We manufacture every lock ourselves rather than buying them in.

Not covered here? Ask us — we would rather talk you into the right lock than sell you the wrong one.
