Angle Grinder Resistant U-locks 2026: Litelok X1 Mini Review

Gear Recommendations:

• Locking a single bike with a normal bike frame? Litelok X1 Mini!
• Want more space to lock 2 bikes or a bike with bulkier/awkward dimensions? Litelok X1 (or Litelok X1 Plus for an epic 10″ long lock)
• Cheapest angle grinder resistant lock that’s also huge? SkunkLock Carbon (amazon)
• Want more security? Read below for the absolute most secure anti-angle grinder locks

It’s been over a year since I first posted about angle grinder resistant locks like the Litelok X1, and it’s been great to see more of them out on the streets! I’ve seen angle grinder resistant, anti-grinder, angle grinder proof locks like the Abus Super Extreme 2500, Kryptonite New York Diamond, Hiplok D1000 and DX1000, and more! Unfortunately, some prices have gone up, making the Litelok X1 series less of a slam dunk value, but still worthwhile for its security, weight, and cost. Fortunately, Litelok has also released the Litelok X1 Mini, shaving off some weight and cost while keeping security intact. Like all the locks in the Litelok X1 series, the Litelok X1 Mini has the best balance of weight, cost, & security compared to other anti-angle grinder locks.

A smaller angle grinder proof lock was exactly my wish in my previous post, and I’m excited that it has come true. My only gripe about the Litelok X1 was that it was oversized on my normal bicycle. I could’ve bought the Hiplok D1000 for a smaller lock (and arguably more secure), but the price was and still is too high.

Since price is a huge factor in buying these secure angle grinder resistant u-locks, I’ll first answer the question: is it even worth it to buy an angle grinder resistant lock? Often I see these locks paired with more expensive bikes, which makes sense as these locks are not cheap. Even so, a secure lock that can resist theft is useful for any bicycle you simply don’t want to go through the inconvenience and hassle of getting stolen.

After some price talk, I’ll review the Litelok X1 Mini, go over some of the other angle grinder resistant locks on the market, and by the end of this post I hope you have a new lock to keep your transportation lifestyle safe. You’re locking more than just a bicycle, you’re locking access to freedom, strength, health, and much more.

Is Buying an Angle Grinder Resistant Lock Worth It?

The toughest thing about angle grinder resistant locks is not their hardness, it’s their hefty price tag. We’re talking $180 USD minimum, but closer to $200-260 for the standard of security I recommend. And some of these locks are over $400 USD 😱 (don’t worry you don’t need the expensive one).

While this is very expensive, I do want to make the case that it’s significantly more expensive to have your bike stolen, even if you didn’t spend any money on the bicycle you’re locking up. Buying a bicycle that fits you well and rides well is not a simple task. Just because you have a bicycle now doesn’t mean it’s easy to replace. If you have your bike stolen, you need to figure out what kind of bike you want, search for it online, in stores, on used marketplaces, tune it up to fit you again, and then re-buy all your accessories that got stolen along with your bicycle. When my bicycle is commute ready, that means I have wheel locks, a seat lock, and a bike rack at the very least. That right there is easily over $100 to replace. Maybe you have a phone mount too, some lights that you didn’t remove, a water bottle cage, a basket, or more. Maybe that bike saddle you were using that fit your bum perfectly isn’t sold anymore. At this point you’re probably at over $200 in JUST ACCESSORIES to replace plus potential priceless nostalgia items lost as well (like that pizza hanging from your seat), and you haven’t even spent any time searching for a replacement bike yet!

What I’m trying to say is a $200 angle grinder resistant lock is completely worth it. Do I wish it was cheaper? Of course. Is it still worth it? Definitely. Can you get away with a cheaper lock and also not get your bike stolen? Probably, and that requires your own judgement call to consider where you lock up your bike and for how long. I still think the Seatylock Mason is a fantastic deal well under $100 for a cheap, light, and strong U-lock that is the best non-angle grinder resistant lock you can buy. I wouldn’t recommend you get anything cheaper for all the reasons I just stated above on why I think even $200 is worth it.

I am currently locking up my bike that I bought secondhand in 2016 for $700. The initial cost of my bike is barely a factor in what lock to buy. I think of it, but I remind myself that if I lost this bike I wouldn’t just be able to buy another bike like it for $700. Inflation, accessories, the feeling of this bike specifically all mean this is a priceless item I want to lock up seriously. And when I eventually get a new bicycle, I can re-use the same lock for a different bike!

While we’re on the topic of bikes being stolen, as an extra layer of protection, I also have my bikes added as “extra coverage” on my renter’s insurance with Lemonade. If you don’t have renter’s insurance, it’s another expense likely worth the cost. When you add a bicycle as “extra coverage” you’re covered deductible-free, which means they’ll pay out the full value of the bike even if it’s stolen from the street. But hopefully your angle grinder resistant lock will make sure you never need that coverage! You can check out Lemonade quotes below:

Reviewing the Litelok X1 Mini: Short, but Wide

The Litelok X1 Mini lives true to its name. It’s literally the exact same lock as the Litelok X1 but shorter. Notably, its width makes up for its shortness enabling it to still lock around larger posts and sometimes both the wheel & frame! Here are some stats:

• Weight: 3.26 pounds
• Width: 3.91″ (99 mm)
• Length: 5.4″ (137 mm)

Although I first fell in love with the Litelok X1, now there’s a shorter lock in town and I’m into it. Here’s mostly what I wrote about the Litelok X1 plus the changes:

• Angle grinder resistant, destroying discs that try to cut it (🔥)
• Coming in at 3.26 pounds, it’s only a pound more than other competing non-angle grinder locks while being significantly more secure.
• Double locking shackle that doesn’t bend after one cut (needs to be cut twice to be defeated)
• Convenient and unobtrusive key weather cover (silicone self-sealing kinda like a vibrator charger actually…)
• Sexy looking reflective strips all over it, enhancing safety in the dark if your lock is mounted 🎆
• Soft coating that won’t damage your frame
• A secure mount sold separately that keeps your lock safely on the bike with NO RATTLING! I am loving how quiet this lock is while riding. Note: the mount is cheaper if you buy it as an add-on when buying the lock.

Overall, I’m shifting to use this as my main lock since the Litelok X1 regular size was way overkill for my size needs, but I will miss the versatility of the bigger lock on the rare occasion that I have a friend’s bike I want to lock up too.

The Litelok X1 Mini is Short and Squatty

While the shortness of this lock is what’s appealing about it, I noticed it’s a bit shorter than all my other small locks at 5.4 inches. I was a bit worried I’d have trouble locking it up, but soon realized that it’s also wider than all my mini locks! The extra width makes some of the difficulties I’ve had locking up with my smaller locks moot, since part of the issue was I always had to make sure the lock was fully parallel to the ground to maximize its width to fit around poles. The Litelok X1 Mini won’t have that problem, since even at an angle the width is big enough to fit around most poles.

Even so, a while ago I shared tips on locking a small ulock when I recommended a small Abus lock. In that post I have tips on how and where on your frame to lock your bike that might be helpful if you get the Litelok X1 Mini. Geometry and angles are important here haha.

Usually, in a place where bike theft is high there are also ample bike racks and well sized poles and posts to attach your bicycle to that make a mini ulock easy to use. Big cities have bike theft, and big cities have bike racks. (If they don’t, you can often request them wherever you want!)

Mounting the Litelok X1 Mini on your Bicycle

Litelok sells 3 different options to mount or carry its ulocks:

1. Tactical Mount of Litelok X1 Mini, the most solid way to hold your Litelok.
2. Twist n Go Mount for any Litelok X1 – While the Twist n Go mount was not super secure when using it with the Litelok X1, I’d assume the smaller and lighter Litelok X1 Mini might handle it a bit better.
3. Hip Holster to carry on your belt if you’re into that (I am not)

The tactical mount is the most solid way to hold your Litelok. It was super easy to use for my Litelok X1 regular, but the Litelok X1 Mini mount I received was pretty tight on the lock, so it was a bit finicky to fit into the mount sometimes. I had to make sure the Litelok X1 Mini was completely perpendicular to the mount as I put it in or it seemed to not fit. This probably depends on the manufacturing tolerance of both the lock coating and the tactical mount, so YMMV, but maybe you’ll need to fiddle with it the first few times.

You need to lock the Litelok into the mount.

The tactical mount looks fantastic on my small road bicycle, and now I can fit my water bottle cage on my bike again! That was annoying that I had to remove my water bottle holder when using the tactical mount with the longer Litelok X1, and then for a long ride where I put the water bottle holder back on I’d have to either take a different lock or put the Litelok in my pannier bag.

When Do I NOT Want the Litelok X1 Series? The Best Angle Grinder Resistant Locks Compared

Clearly you can see I’m a fan of the Litelok X1, but there may be reasons you don’t want it or its mini counterpart. The Litelok X1 series is the best balance of security, weight, & cost with reliable and consistent construction, but if you care more about one of those traits specifically or have a specific use-case, a different lock may be better for you.

Cheapest Cost

This one is always slightly changing, so for up-to-date numbers you’ll have to click on the links to confirm, but I’ll try to keep the cost vibe generally up to date here to direct you in the right direction.

1. SkunkLock Carbon (amazon) – this lock is under $200 (and doesn’t smell), so definitely the cheapest angle grinder resistant lock you can buy (especially if you’re in the USA). However, it’s unnecessarily huge (unless you want that for a bulky bike) and therefore also heavy. If you don’t mind a heavier, bulkier lock for a bit cheaper though, this one is for you. The hollow area that was filled with noxious gases in the SkunkLock Chemical is instead filled with angle grinder disc destroying silicon carbide. The added bonus of the SkunkLock Carbon is the SkunkLock brand that may scare thieves into leaving your lock alone for fear of noxious fumes 😄
   • SkunkLocks don’t have any official mounting options, but this universal mount will likely work. Check out my post on attaching a u-lock to your bike for more options.
   • SkunkLock has a Skunk Your Bike program where you may be able to get a discount if you fit a certain demographic. Check the terms to see if one of their coupons may be right for you!
2. LiteLok X1 Mini is priced just above the SkunkLock Carbon and has all the benefits described earlier! The tactical mount will cost extra but is cheaper when bundled with the lock.
3. Many other locks are priced in the mid $200 range, but often more expensive than the Litelok X1. If you can find a deal, you may be able to buy the Abus Super Extreme 2500, OnGuard RockSolid, or even the Kryptonite New York Diamond for cheaper (but note their caveats I will mention in a moment).

Best Security

If you want the absolutely strongest lock no matter the cost & weight, there are other locks that fill the bill. However, because manufacturing an angle grinder resistant lock is not an easy task, some other companies that have stronger locks have had issues with build quality in the past, and some of the less secure stock might be floating around depending on the seller.

1. Abus Super Extreme 2500 – some of the longest cut times recorded by testers, but the original version had a weakness so might be some old stock. Also very large (same as the SkunkLock Carbon) which is great for bulky/awkward bike lock ups, and therefore also heavy.
   • It comes with a weird frame mount that may interfere with bike panniers too, so look into how you’ll want to carry it on your bike. This universal mount may also work.
2. Litelok X3 – A beast with no build quality issues, but also incredibly expensive…you might not need this as another lock could provide similar security for cheaper.
3. Kryptonite New York Diamond – The absolute strongest lock if you get a good batch, but there may be some old stock lying around with certain sellers. The Amazon reviews are full of people exchanging locks to get a good one.
   • The mount is the classic standard Kryptonite mount that I think works great and is very versatile. This universal mount will also work.
4. Hiplok D1000 or DX1000 (smaller and bigger versions) – Hiplok has had no build quality issues I’ve heard of and consistently performs well if not the absolute best.
   • There are a few mounting options including a pouch and a bracket mount. This universal mount might work but not sure because the Hiploks are square. Check out my post on attaching a u-lock to your bike for more options.

Lightest Weight

I thought the Litelok X1 Mini would be the lightest anti-angle grinder lock coming in at 3.26 pounds, but there is one lock that takes the lead for lightest!

1. OnGuard RockSolid – This lock comes in at 3.09 pounds with dimensions of 3.15″ x 6.89″. Note that it is narrower than the Litelok X1 Mini, which is probably why they got it even lighter. I don’t generally recommend this lock because I’ve heard of build quality issues, but if weight is your primary concern it will still be angle grinder resistant!
   • No official mount available, but since it’s smaller and lighter it’s a bit easier to find other mounting solutions. This universal mount will likely work. Check out my post on attaching a u-lock to your bike for more options.
2. All the other locks come in at over 4 pounds and the Litelok X1 comes in at 3.77 pounds and is likely plenty long, so maybe you just want that one?
3. If you really need something under 3 pounds, maybe you don’t need an angle grinder resistant lock and can go for the 2.2 pound Seatylock Mason 140.

Bulky Bike Frame or Awkward Lock Up

Sometimes you have a fancy ebike or a cargo bike where the frame isn’t very accessible when you’ve attached all your accessories. This is where you need a huge lock. Here are some locks that can do the job while being angle grinder resistant:

1. Litelok X1 Plus – A huge 10″ length with the same near 4″ width. I’ve never really mentioned this one since I think it’s totally overkill, but if you have a specific need this could be your super long anti-angle grinder ulock.
2. Hiplok DX1000 – At 4.4″ by 8.1″ this is the widest anti-angle grinder ulock available
3. Abus Super Extreme 2500 – At 4.1″ by 8.8″ it’s pretty big.
4. SkunkLock Carbon (amazon) – At 4.1″ by 8.9″ it’s also pretty big, and pretty cheap!

Lock Your Bike with an Anti-Angle Grinder Lock and Ride On

There it is folks, your best angle grinder resistant lock options for 2026. Take an expensive cargo bike, an ebike, a priceless bike, or whatever you want and have no fear locking it up outside. It can be tough to leave your bike outside for the first time, but with an anti-angle grinder lock you can take that first step! Here’s to hoping these companies can bring the prices down over time and make them even lighter while keeping the security intact.

And remember, now that you have an angle grinder resistant lock, make sure you lock up to secure bike racks and poles! Since your lock may no longer be the weakest link, a thief may be crazy enough to destroy public property to get at your bicycle! If that really starts happening though, I’d guess cities and cops would be forced to get more involved in the bike theft issues.

Happy biking!
