A cable lock is asking for trouble.

5 Good, Unbreakable Bike Locks for 2018: Lightweight Options & Tips

What’s the Best, Strongest Bike Lock for Theft-Proof Security? 5 Reviews

Bicycle theft is epidemic. In my city, I spend more time worrying about my bike getting stolen than my car. It’s true!

The ugly truth is that bike theft is common and difficult to combat. If your bike gets lifted, chances are you won’t see it again.

The best precaution against a theft is to be smart, and to buy a good lock. The best bike bike locks are secure, virtually unbreakable and simple to use.

Unfortunately, I mostly see two types on the street these days: flimsy cables and cheap U-locks.

You might as well put a big bow on it it.

So what’s the best bike lock to keep your ride secure? I wrote this article to review a handful of good, strong bicycle locks, and to explain how to most effectively use them.

For each, I’ll offer pros and cons, and hopefully point you towards some great, proven brands. Let’s look at what’s out there!

What Does a Top Rated, Strong Bike Lock Look Like?

If you’re hunting for a good quality bicycle lock that’s nigh unbreakable, there are a couple of essential features you absolutely need.

In a nutshell, it comes down to style and material.

What’s the most effective style?

In my opinion, the best, most secure & theft-proof bicycle locks on the market are U-locks and chains. Both can be made from nearly uncuttable metal, and both are fairly convenient to use.

The least effective is the cable lock. Why? They can be easily cut with brute force or bolt cutters. A thief can get through a cable lock in ten seconds. They’re vaguely useful for securing components (like your saddle, for instance), but even that is a risk.

What’s the most effective material?

In my experience, the best and strongest bicycle locks are made from hardened steel, or exotic materials like titanium.

Many cheap bicycle locks are constructed using softer alloys. Bolt cutters, hacksaws, and sawzalls cut cheap metal like butter.

The more expensive kind are made from hardened steel, and they’re impervious to hacksaw and bolt cutter attempts (unless the thief has 6 hours to spend cutting).

Really, the only way to get through hardened steel or titanium is by using an angle grinder. Unfortunately, thieves use those, but they’re noisy and cause a shower of sparks, so in the open they’re very conspicuous.


1) Kryptonite Fahgettaboudit: One of the strongest bicycle locks, with good reviews

Pros: Double deadbolt shackle, hacksaw proof, vinyl coating

Cons: Weighs about 4 pounds

The venerable Fahgettaboudit U-lock, by Kryptonite, is one of the most unbreakable bike locks you’re going to come across. It’s not the cheapest, but it will give you peace of mind.

The whole lock is made from hardened steel that’ll easily turn away bolt cutters and hacksaws.

True story: I was once hired (legally) by an apartment building to clear out a locker of old bikes from former tenants. With bolt cutters we made swift work of the cable locks, but when we came across a Fahgettaboudit, we were forced to admit defeat.

The lock has a double deadbolt design (the double shackles mean a thief would have to cut through both sides to compromise it). It uses a disc cylinder that’s difficult to pick.

This lock is pretty heavy at over 4 pounds, but it’s covered in a vinyl coating that prevents it from scratching up your bike. This coating lasts a long time too.

The weight is unfortunate, but hardened steel is heavy, and it’s worth it for the protection it adds.

A couple of notes: you may want to give the lock cylinder a little bit of grease if you frequently keep it in the rain. Also, this lock doesn’t come with frame mounting hardware.

Overall the Kryptonite Fahgeddaboudit reviews really well. It’s one of the toughest and strongest bicycle U-locks around, and therefore it’s on the top of my list.


2) TiGr Mini: A lightweight bike lock that’s also strong, secure and effective

Pros: Extremely light, quick to attach / detach, great as secondary lock

Cons: Small size makes it less useful for large frames

Many great bicycle locks will review well for security and ease of use, but they fall short in one key category: weight. Hardened steel is heavy stuff. Conversely, lightweight bicycle locks tend to be less secure. The lighter the steel, the deeper the compromise.

Unless you move away from steel. To titanium. Then magical things happen!

The TiGr Mini is an amazing little all-titanium lock that’s extremely lightweight. Despite that, it’s one of the strongest U-locks in this category. Titanium is an extremely strong and durable material. They make jet planes out of the stuff.

The flat shape of the lock body and the ductile qualities of titanium makes it resistant to traditional attacks. Here’s how:

  • Bolt cutters aren’t super effective against it. The flat material means cutters hit their stop before compromising the lock. Check it out yourself.
  • The small size of the TiGr mini gives thieves no room to work.
  • Titanium’s natural hardness makes an attack by hacksaw incredibly labour intensive.
  • The hardened, stainless steel lock cylinder is difficult to pick.

The TiGr is dead easy to use. You turn your custom key until the cylinder pops, squeeze the attaching rivets, and it opens. To close, pop the cylinder back into place.

Titanium is also flexible. You can stretch the TiGr mini to get around your frame and whatever you’re locking to, then squeeze it closed to attach the cylinder. That’s super useful.

The total weight is a featherlight 490 grams (0.9 pounds) and it comes with a frame mount. It’s a wonderful auxiliary lock, good for securing wheel to frame, for example.

The TiGr Mini 4 inches (10cm) at its widest point, and 10.5 inches (or 26cm) in total length. Comparable to a U-lock. If you have fat tires or a beefy frame, you’ll probably want to opt for the larger version, called the Mini+.

Small and lightweight, this is one of the best bike locks; it reviews really well and I love using it.

Thanks to TiGr for sending me a review unit to check out!


3) Evolution Chain: A nigh unbreakable bicycle chain lock, among the best around

Pros: Probably the most secure lock you can find, easy to attach

Cons: It’s very heavy

No, I’m not a Kryptonite rep, I’m just a fan! But I’m really into chain locks in general, for a few good reasons.

  • Chains are flexible like a cable, and easy to attach, even around oddly-shaped items. That’s super handy.
  • They’re durable, if made from hardened steel. A lock like this will probably outlast your bike.
  • They’re very difficult for a thief to cut, even with an angle grinder. The links move around and shift and it’s just not fun to cut through.

The outstanding Kryptonite Evolution chain lock ticks all three of those boxes. Each chain link is thick and strong, made from six sided (hex style) manganese reinforced steel. Good luck getting through one with a hacksaw!

You’ll be impressed by the size and durability of the links, the pictures just don’t do it justice.

It’s latched by a small Kryptonite shackle that’s also reinforced, with a complex, four-cylinder design that mimics their bigger U-locks.

The chain is smartly covered with a nylon fabric material. That keeps the links protected, but more importantly it prevents your frame from being scratched.

This lock is heavy! It comes in at around seven pounds. Good protection has its price, I suppose. Weight notwithstanding, I’d swear by a hardened chain like this one. There’s a reason why professional bike messengers use them.

I’ve heard reports that the lock cylinder can get sticky if it gets wet; I’d just give it some oil if that’s the case.

The Kryptonite Evolution chain lock reviews really nicely. It’s a very good bike lock with secure, strong features. Not exactly lightweight, but your bike is ultra-secure, so who cares?


4) Bordo Granit:  A foldable bicycle lock with great features, strong and light weight

Pros: Very light, folds up to become extremely portable, unique design

Cons: You need to use the key while locked and unlocking, a bit expensive

Sometimes a great strategy is to throw something at a thief that they aren’t use to seeing. The unique, foldable Abus Bordo Granit is an interesting lock design that’s efficient for the user but also effective and light in weight.

The lock works similarly to a chain or cable re: locking flexibility. It consists of 6 metal bars that fold out, chain-like. Each bar is riveted to the next, but because they’re flat you can fold it up into a very small size.

It’s one of the best bike locks for both weight and portability. It weighs in at 2.6 pounds, and when folded it is more compact than any U-lock.

It’s coated in a rubberized material that prevents it from scratching the hell out of your frame.

The lock cylinder is high quality and difficult to pick. The metal bars are made from hardened steel, and like other high-end bicycle locks the only real way to break it would be using a grinder.

It comes with a frame bag and mounting bracket that prevents rattling.

Notes: it does require the lock itself to be turned when both unlocking and securing, which is a bit of a hassle compare to others that just ‘click’ in place. Also, the rivets will loosen as you use it. According to Abus, that doesn’t affect the security of the device.

This is a fantastic bicycle lock for a rider who wants a nearly unbreakable system with portability and light weight.


5) Master Lock Street Cuffs: An inexpensive, lightweight bike lock with great utility

Pros: Unique design, easy to use, great for tight spaces, inexpensive

Cons: You might get strange looks

As mentioned, it’s an advantage to use a unique lock thieves don’t often see. These awesome ‘street cuffs’, by Master Lock, are a fantastic bicycle lock with some nearly theft-proof features.

They are essentially regular handcuffs, which seems weird until you realize that it totally isn’t. They have a single link chain that pivots on both cuffs. For that reason, it’s really quick and easy to secure your ride in a pinch. Just attach one end to your bike, and the other to a convenient bike rack or signpost.

One small caveat: if someone digs through your backpack and finds them, you might have some explaining to do.

The cuffs are pretty small, and they can be folded over one another to save space in your pack. It’s probably the most portable lock on this list.

They work great on their own, or they make a wonderful “secondary” lock to augment your existing setup. I like to use them to secure my wheels.

The whole works are made from a hardened steel, both the cuffs and the links. They’re only really vulnerable to a grinder attack. Their small size makes them difficult to cut off a frame without damaging it. The unique cylinder is very difficult for a thief to pick.

They’re a very lightweight bicycle lock at 2.9 pounds, and have a reach of about 12 inches. If you need more reach, opt for the 9 link version, which is 22 inches long.

Convenient and inexpensive, these cuffs will get you tons of comments. They’re one of my top bike locks, with positive reviews, good strength and nearly unbreakable construction. Check them out!


Beyond The Lock: Making It Secure and Safe

I’m surprised by how often I see a poorly locked bike. I have even seen bikes with nothing more than a lock securing the rear wheel to the frame (as though a thief couldn’t simply pick it up). The largest and most unbreakable bike lock in the world won’t save your bike if it’s not secured properly.

Don’t lock it up in an alley

If you don’t want your bike to be stolen, don’t leave it somewhere where it can be easily tampered with. Choose a busy place with lots of foot traffic and it will be much safer. People tend to notice things like angle grinder sparks.

Leaving it somewhere tucked away is trouble. It gives a potential thief time and space.

Don’t give thieves room to work

As a rule of thumb, don’t give thieves a lot of room to work on your lock. You want the smallest possible lock that works. That way, they can’t reposition it to make things easier to cut.

Make it more trouble than it’s worth

A thief is going to go for low hanging fruit first. If you make your bike seem like a lot of trouble to steal, they’ll probably move on to easier pickings.

How can you do this? Use a small, effective, hardened lock that’s difficult to cut. Secure all your removable components (like the wheels). Lock it up in a conspicuous area. All these things will help.

Learn how to lock it up properly

An excellent bike lock strategy

A good bicycle lock strategy. Neither wheel can be removed, the frame is secure, and there isn’t much room for a thief to work. If possible, run the lock around the seat tube, a chainstay or seatstay for extra security. (Photo Credit: PJ Souders

A lot of people don’t know how to properly lock up their bicycle. I see cables looped around the wrong places, or nothing but the wheel secured.

Ever see a rusty bike lock with just a wheel attached? The thief simply detached the front wheel and made off with the rest of the frame!

Here’s the proper way to do it:

  1. Find a post to lock around.
  2. Remove your front wheel, and place it beside your rear wheel.
  3. Run your lock through your rear wheel, around one of your chainstays or seatstays, then around the post.
  4. This works best with a chain, or a larger U-lock.

That’s all you need to do! In one go, this secures your frame and wheels, with one lock. It allows you to make the most of one lock. If that all sounds like gibberish, check out these awesome diagrams. I prefer the middle technique.

(If you don’t have a removable front wheel, consider a secondary lock to secure it to the frame.)

It’s actually really quick to attach your bike lock in this way, and it’s very effective!

    This post will end up being a mile long. Sorry.

    Lock companies are capitalists. They know how your American brain works. “If a lock doesn’t cost this much, it must be junk!” and it works, I own 3 of the locks above and probably another $300 worth in other chains/padlocks/U-locks…

    And their marketing is usually cool. Blowtorches. Cutting tools bending. It’s fun to watch videos of a lock taking a bullet, but you never see the gun being pointed at the guy with the key, right? It would defeat that beautiful marketing campaign, where everyone is interested in the physics of the stacked plate padlock, and not what it supposedly secures.

    When the reality of it is, it matters more WHERE you lock up and HOW you lock up, than what you lock up with. These types of articles are written so you think your bike will be left alone in Nowheresville. If that were the case, they will have all the free time to grind away even the most hardened steel.

    I have a wrought iron street level window guard, and have to frequently cut off some inconsiderate jerk’s bike and move it over to the signpost or the bike rack. If you try a long-term lockup on my property? Better run to the local bike shop, I “donated” it. The point? All of them can be cut off in minutes with a HSS rotary tool and cutoff wheels, especially when you have the law on your side and aren’t worried about grinding noise nor sparks nor NYPD stopping you. Yes, even whatever fancy lock David George above thinks he has, I can remove it. Easily.

    But even if you lock up your bike in a legal manner, nothing matters more than your safety. And in some sketchy urban areas, they will stomp your rims and just thrash your ride in general just because you were dumb enough to chain it up. Take it INSIDE with you… a lock & chain is just for running into the store for 5 minutes. NYC streets are full of bent forks ‘n frames that are still securely locked to poles, those rusting relics are good reminders about what purpose a lock serves. (did you know the City has specific workers to do bike frame removals?)

    As Larry points out farther back, flesh is much softer than steel, and has pain nerves. It’s easier to steal a bike if the thief punches you in the throat and just takes it, while you’re laying on the ground gasping for breath and trying to see how badly smashed your iphone is, if it can still dial 911, through tears… it’s the world we live in. It’s difficult to get a carry permit in NYC, much less to wear a 7# auto in bike shorts, so I guess we all need to take up krav mgah.bike defense tactics. Sadly everyone knows who little Autumn Pasquale was… I’m just glad it doesn’t happen more frequently.

    I know it seems weird to joke about this to some of you, but as both ex-military and NYCer, I’ve come to terms that crime is just part of urban life… like the Chicago shop owner who had a guy walk in and wheel out a $7000 Pilot… let the cops do their jobs, if you have replacement cost insurance. Screw that bike, and that fancy lock!

    Finally, remember that lock integrity is a concept that most of us have no idea about. We HAVE to take the manufacturer’s at their word that it’s this, that, or the other. Physics, metallurgy, sure if we have a scientific mind we understand the principles, but as for the whole lock? They keep it private and proprietary as possible. I’m sure Kryptonite wants you all to forget this, but anyone over 30 – but do you remember when their top-of-the-line circular keyed lock, both hasp/chain and U-lock, were instantly defeatable with a chewed-up Bic pen? Literally one second. Smack! Turn! Gone. It’s not as bad as finding poison in your Tylenol, but it could have easily killed the company. You want to trust your lock. For all the common man knows, every “ultimate” lock is just as easily defeated by a professional, but professional thieves both real and electronic, don’t run to youtube to post brag videos – they keep the secret so it’s usable when the time comes.

    Look, this site is bikesmarts, and our host wants both money and free gear for hosting and reviewing things. And making people feel safe is a profitable business model. But please look at this with eyes open. Look how many replies here mention stolen bikes.

    So while we love him, Will’s reviews are just that, product reviews. Even if this were a field test, it doesn’t matter. Please don’t think a lock review, of any lock, is some be-all security thing to yearn for. Security is an idea, a concept. And locks are very useful for keeping honest people honest. But beyond that? Your brain is a better security tool than any lock, and it too can fail.

      NYC_Critical_Masser: Good points! You’re right that WHERE you lock up is as important as how. I consider bike locks a safeguard against crimes of opportunity. But they won’t stop a determined thief. As you say, a rotary tool can cut through almost anything, and a bike lock won’t save you from a mugging (unless you smack the thief with that heavy chain.) Ultimately, using your brain is the best way to avoid a nasty surprise.

      For the record, I do earn some money off ads here (it’s part of my living), but I always refuse bike gear offered to me. I figure it messes with the integrity of the review. So the locks reviewed here are a selection of the best ones I know of. Helping people is still priority one for me.

    I was using a U Lock made by BELL that claimed it was hardened steal. I didn’t do much research on how hard it was because my bike was a Schwinn Ranger that had white paint splattered all over the frame and back rim. I was riding back from Home Depot when a small can of paint I was carrying fell through the bottom of my bag and EXPLODED all over me and the bike. So, I thought to myself…who would steal a bike all messed up like this? It’s ugly and they would be spotted right away. Man oh man was I wrong!!! I had the bike locked up to a 1 inch steal gas line about 10 feet from my back door and 5 feet from my bedroom window. I was lying in bed Sunday morning when I heard this loud clunk which was the brazen bike thief walking up the complex driveway with bold cutters in hand and SNAP! Off he goes with my bike. OK…so the good part is, I’m 5,10 and this bike was too small for me. I am now in search of a hybrid but am more concerned about how to lock this bad boy up and maybe even track it. Is Spybike available yet or do you have any other recommendations for something that can track when it’s stolen. BTW…did you see how Tesla has a built in network to track you bike if one of their bikes is stolen? THANKS!!!

      Hi Steven, I’m not sure if Spybike is ready yet, but I personally I’m skeptical whether it’ll actually help.

      Say your bike is stolen by a professional thief… are you just gonna go knock on their door? Will the cops take the time to visit them?

      Not to mention, I believe thieves will quickly figure out how to mute the signal or compromise the tracking.

      The most headache free thing is to simply buy a truly hardened steel lock (avoid Bell!) Those bolt cutters won’t work on a Kryptonite chain. And if you can, avoid leaving it outside overnight. Hope that helps!

    Hey do you know if there’s a U-lock that clicks into lock by itself and doesn’t have to be locked shut with a key? So much handier to use when you do multiple trips around town in a day.
    My 8 year old U-lock just broke so I’m looking for the best option. It kind of cracks me up that we have computers in our pockets but the technology for bike locks is so primitive (why do they all have to be 5 lbs??)
    Thanks!

      Hi Alex, the u-locks I know of all require the keys to close. 🙁 Yeah they’re heavy and primitive, but that’s because thieves have had great success using smash and cut techniques. Funny that technology can’t get past caveman tactics hey?

    I just bought a bike, first one I’ve owned in 15 years. Im really worried about thieves, partially why I only bought a 500$ bike, I just can’t justify buying something more its rather sad. We really cant have nice things. Anyways, have you looked at a frame lock strategy? I will be ordering one from axa security. Seems like something that is common in europe but not at all here in Canada/USA. Im a little conflicted that I’ll have to spend more on a chain, ulock and frame lock than what the bike is worth. Also will add 15lbs to the bike which kind of makes my goal of it being a daily commuter not really appealing. It may be overkill but I view this as safety for myself, I dont want to go to jail for life for crushing a thieve’s skull on the sidewalk should I catch one in the act.

      Hi N, you’re right that frame locks are not as common here. Like anything though, I feel a dedicated thief could get through it… because even if they can’t pedal away due to the shackle, they can easily pick the thing up. If you were to use the optional cable, then it has the same vulnerabilities as any other lock. I still think the best strategy is to use a chain lock through both wheels and the frame, and to lock up in a safe, exposed place. 🙂

    I have been studying proper locking techniques and reviewing locks. I recently was given a nice bike that I had to restore from being left too long outside to the elements. If I were to lose this bike I would be especially heartbroken considering the love and labor I put into it. I appreciate your article, it has taught me a lot on how to properly lock up my bike. I am looking at U locks and possibly a good chain. But I ran across the Onguard Minpin Key less Locking Skewers and wondered what your opinion of them was. I like the idea of the convenience of not using a key (esp. considering others can have them too) but just wanted a professional opinion, in case I am not thinking of something that may uncover an issue with using them.

      Hi John, I don’t recommend the MinPin yet. Sounds as though they’re not waterproof and can lock in place permanently. I’d suggest a different locking skewer for the time being.

    Loved the article! I am sure that I am naive in thinking that I’m pretty safe as a leisure rider of my newly purchased bike. I have an old U lock, probably 15-20 years old; is that still any good? I’m guessing no, because every new preventative has a new way to break it. I was considering the street cuffs; rides to a local watering hole or to the grocery store, not really going on campus (Univ of WI – Madison); which is where I hear stealing of bikes happens a lot. Street Cuffs – Are these going to be good for random neighborhoods, stops off the bike path for libations and maybe the 1 -3 times on campus and downtown? Lots of words for 2-3 questions 🙂 again, thanks a bunch for your article!

    Just had bike stolen from a condo bike room bike locker. A (supposedly) secure bike room, a locked bike locker, but the bike itself wasn’t locked or secured. The criminals apparently shoulder-checked the room door and crowbarred off the door of the locker. I had an Otivia cargo cache on the bike with locks and some bike tools in it. Yeah, it hurts like hell that I literally gave the criminals some extra tools. Anyway, after some research, I’m looking at two Kryptonite NewYork Fuggedabodit u-locks, and either their elite chain or the Oxford chain for securing in the now-repaired locker room. The starts gonna get security cameras (I’m on council). Professional opinion on the locks?

      Hey Len, sorry to hear it, that sucks. In some cases bike rooms are easier for the thief… secluded, private, plenty of time and space to work. The Fuggedaboudit and elite chain should do the trick, as will adding cameras. It’s amazing how that little red light will deter theft.

    i used to take off my front wheel and lock it with my back, then one day i came back to my bike and my forks were snapped, and wheels bent-some people if they can’t steal it, will try and destroy it…… helpfully, it was covered with cctv and the guy who did it was known to the police, I’ve now got a lovely new bike thanks to his bank account….!! 😀

      Hi Marcus, sorry to hear that, sounds like he had a screw loose. But it’s satisfying that even though he messed up your ride, he didn’t manage to steal it due to the lock strategy! And glad the police resolved it for you.

    Great article and validated my own thoughts on bikes and the situation behind what is obviously common sense.

    Its still good to see it in writing I’m very grateful.

    My opinion is you cannot stop somebody from taking your bike if they really want it.

    But by taking instrumental measures to prevent your own bike being stolen as presented in this article will go a long way in not having your own bike stolen.

    Thank you.

    A friend bought hi dollar lock for his trailers because thieves were in area; neighbors stuff was stolen. Friend’s wife lost key to lock. Last resort to access trailers…30 seconds with drill and bit….high dollar lock that was bolt cutter proof defeated. If it has a key hole a drill and bit are seconds from defeating lock. We still try though. Best lock is….hunt for thieves and go jihad on their asses.

    That image you have of the blue bicycle with the gator skin tires and “a decent bicycle locking strategy” with the U-lock is a great way to get your bike stolen. The U-lock isn’t going around the frame at all so, a simple removal of that rear skewer and you can take the whole frame away with the components, leaving two tires behind. Or, if a thief wanted the hubs, he could easily get through those rims in less than 30 seconds with a decent hacksaw.

      Will Henry 23 July, 2016 at 23:31 Reply

      Hi Torben, lock up your bike exactly as in the photo (through both wheels and around a post), remove the rear skewer, and try to remove the frame. Good luck to you!

      The only vulnerability is if someone hacksaws through the wheel and tire. Which is why I also suggest going around the frame also.

      But to steal the bike by removing the skewer is not possible. Give it a try!

    Hello Will.
    I have enjoyed reading you article and posts by others.
    My sons Trek Crossrip elite 54 GY (cost of $1,270.00) was stolen on Wednesday Sept 9th at the University of Arizona campus. That day there were 7 bicycles stolen on the campus according to the UofA campus police. He had properly used the Kryptonite KRY U series 2 STD lock to secure the bike. When he came back to one of the campus racks he found the lock had been picked ! The campus police said that it had been picked with a plastic bic pen !!! Okay, I know these guys are professionals but a bic pen can unlock a Kryptonite Lock ??
    Unfortunately, my son did NOT register the lock with Kryptonite. They do have some type of reward program up to $1,500.00 . I have no idea if they would have paid off in this situation. It doesn’t matter .

    I just wanted to let viewers read this and to beware !
    We will be purchasing another bike and now I am searching for the best way to secure this bike, as others on this site are.
    I am looking a GPS systems now and I have not found one that really gives me comfort. Of course, I am still trying to find suitable locks that can’t be picked. I just spoke with my locksmith and he recommends a lock that has an ACE key, it looks like a coke machine key or a tubular key. I thought the KRY U had a tubular key.
    Anyway, I hope this helps others and I am continuing my search for the best security out there. I don’t mind spending the money on these items IF it works !
    Any help is certainly appreciated ! Be safe everyone.

    I am an avid cyclist in Los Angeles. I did a little research and purchased a great Kryptonite U lock 13mm hardened steel with a security rating of 7. I lock my bike outside my apartment to my railing. In conjunction I also use skewer locks that require a delta tool, and have soldered all allen key bolts full so allen keys do not work – you need to get the solder out with a torch or iron in order to loosen or tighten.

    The other night a thief used an angle grinder on the Kryptonite lock at 3am. My neighbor woke up and caught him in the act and called police while watching his progress. His battery ran out and he was trying to figure out how to get the seat off. At this point the thief was on my balcony pulling at the seat and my neighbor yelled at him.

    He made it through about 1/2 the steel of the U lock so I replaced it with a stronger lock. He was grinding for a solid 5 minutes.

    I also purchased a hardened steel chain as an additional deterrent with a movement alarm. Look up Stockton Tool Company alarm lock. It’s 10mm steel chain with a 110 DB alarm for 39$. Remember with a chain you have to make 2 cuts to break it as apposed to just one in a U lock. Now this thief is going to have to cut through over 50mm of steel to get my bike with an alarm blaring. I wish him the best of luck.

    Hey Will Henry… How about those special bolts with accompanying tools they sell for wheels (assuming they are bolt-on track wheels), seatposts, stems etc? They sell the same type of thing in the form of bolt-on skewers for standard wheels as well. Are these things effective at all? Or do thieves scour the Internet for all the different types and buy up the tools?

      Hi Kitt, you’re talking about things like Pinheads skewers, right? I’m actually planning to write a separate article on them. Short story is: they’re great for added security. And most thieves won’t have the tools. However, a handful do, so they’re not 100% secure. Short answer is: I’d endorse these systems. Anything that makes a thief move on to easier pickings is worth investing in!

    Just got back from a bike trip with 5 family members down the C & O Canal Towpath to Washington DC. The last evening in DC we were having dinner in Georgetown with our bikes locked with cable locks to a bike rack on very busy M street. Came out to find all 5 bikes had been stolen, my son’s was only 2 days old. Thieves rode up on 5 bikes and within seconds had used bolt cutters and taken our bikes and left theirs (which the police confiscated). Thanks for the hospitality DC! Heading out now to buy a kryptonite BEFORE I buy some new bikes. Lesson learned.

    I just got a bike and I live in NYC. I feel like I’m spending more time on finding the right lock than I did on finding the right bike! It’s just a used bike off craigslist, but I really love it. I think I might get the cuff locks for the wheels and the fughettaboutit for the frame. Taking a wheel off every time I lock it, is just not realistic and not easily done on this bike. I have to see if it’ll work, but that’s my plan, I think.

      Hi Alyson, I hear you. You can definitely do two locks, and I think your strategy is a good one. Best of luck!

    Lost my mountain bike even though it was secured to the house with cable and a lockwood padlock. Never found a trace of the lock, I guess they took it with them. But like my local bike dealer told me, if someone wants it bad enough they are going to take it no matter how well you lock it up. Waiting on delivery of my new bike and will keep it inside from now on, and buy a better lock.

    My son’s brand new Cannondale bike was stole from inside his condo bike room while locked up with the KRYPTONITE FAHGETTABOUDIT!!! How the heck did they steal it? The bike and lock were no where to be found.

      Hi Tracey, sorry to hear that. Unfortunately, no lock is invincible if the thief has enough time and space to work. I’d guess they used an angle grinder… condo bike rooms are perfect for that kind of theft, far from prying eyes. Do they have a security camera / card controlled door? If so you might be able to track down the culprit using the video timestamp and door access records.

    My son used a Kryptonite U lock on his bike for 9 years. Someone finally figured out how to break them fast & quietly. His bike was stolen 2 days ago. Fortunately, we spotted the bike a few blocks away, abandoned yesterday. I had figured the bike was gone for good. We are investigating the possibility of getting a GPS tracking device for it. There is one that involves replacing the handlebars and another that involves dropping the device down the seat post. My concern about GPS is “Battery life” because it sounds like both devices must be re-charged every 9 hours.

      Glad to hear you recovered the bike. You could also look into the Skylock system, which works with Wifi. If you go for a GPS system let us know how it works out!

    That picture is actually a very unsafe way to lock a bike. You can saw through that wheel with a hack saw and then just yank on the bike and the lock will pull through the wheel.

      Hi Samson. I’m planning to update that photo. In the meantime if you read through my strategy suggestion carefully, you’ll see that I already recommend going through the triangle, wheels and around the frame to nullify a hacksaw attempt.

    I have one problem with the locking technique used in the photo. It seems to me that it would be very easy to release the rear wheel and take off with just the frame. Looks like there’s plenty of space to do it too. Lock the frame people.

      Hi Sean, challenge accepted… try it! It’s not possible to remove the wheel if the u-lock goes through the rim inside the triangle. You’d have to cut the wheel. (Cutting a wheel with a hacksaw IS possible, though very rare, so yes be sure to lock through the frame too.)

    Ohmygosh! I have had 4 bikes stolen since I purchased my first bike 19 years ago! And, with the exception of the last one, I have always locked it.
    My favorite bike thus far was a nice Electra Retro that had all the bells and whistles. I love d it! The frame was locked to a busy corner outside the restaurant where I was working. I was SO BUMMED to complete my shift, walk outside, and see my helmet lying on the ground next to where my bike was locked!
    The last bike that was stolen was taken from inside my garage. Normally, even when inside my garage, it would have been locked to my fiancees’ very expensive downhill mountain bike. But, for some reason, we hadn’t locket it. Our garage is attached to our neighbors garage. Well, there was a space that is missing between our garages that a person could walk through. I had asked the neighbor to please always double check that his automatic garage door was closed. Well, one day I noticed he had left it open. I got home from being out for about 2 hours. When I returned, my bike was gone.
    So, now, other than installing some sort of barking razor blade security system that is triggered when someone other than me rides it, I will go with one of your recommendations from this article. And, perhaps even use TWO locks (as I had done previously).

      Haha! I’ll be the first in line to buy your barking razor blade system! Get a patent on that quick!

    Had a half decent mountain bike stolen 2 and a half years ago outside a station after 3 months of locking up outside because I was naive and had 2 rubbish locks.
    I’ve been locking my new mountain bike for nearly 2 years now with 2 good gold rated locks, one a abus chain and one gold rated d lock from halfords and I lock it properly.
    I lock the bike up as well next to bikes that have rubbish cable locks. Haha.
    I put my myself in the thief shoes, and try to think how he would think, so I don’t think he will think twice about messing with mine especially when 40% of the bikes you break with your bear hands.
    Watch Barry Manson on you tube, it helped me a lot.

      On top of that you need to paint your bike in an ugly color. Camoflage all expensive parts – paint on top of original model names some low end gear names =D and paint a cracks and rust!

    Help me with your method for locking the bike. Not securing the frame within the lock seems like its just asking for trouble. Instead of having to cut through the lock, the thief can just cut through the wheel. Wheels are easily replaced and the metal is “thin” enough that you could probably use a set of bolt cutters.

    Cut the rear wheel, remove the lock, take the whole bike minus the front wheel. You get the frame and the derailleur. Throw on some inexpensive rims, list on CL.

      Will Henry 27 February, 2015 at 19:40 Reply

      Hi Nate, it’s true that rims are easier to cut through than a frame, but it’s still not easy. Bolt cutters would have a very tough go of it. A hacksaw could do, but it’s very noisy. Tires have wire running through them, and even once it’s cut you really have to wrench it to get it out of the triangle. Plus, the rear wheel is usually the most expensive and prized part on the bike. So realistically, thieves will look for easier pickings.

      That said, you’re right that it’s definitely more secure to run the lock through both wheels and the frame, so if possible, do both!

      I recently saw a video of a ‘hack through the rear wheel’ success on Youtube. I don’t think you’ll see it happen much in the real world, but I am going to update my strategy anyway. Thanks for the comment!

    thanks for your post. Just starting out with biking (my car broke down and Im really hating this whole dependency on a car). great tips!!!

      Hey, thanks for the reviews. Thieves snapped the padlock to my condo complex’s bicycle storage garage, then cut the cable around my TWO $800+ GTs, and took them, but (fortunately) left my gal’s GT. I bought a new GT Karakoram, and am buying a Kryptonite Fuhgettaboudit and am considering a Spybike seatpost. Thanks for the advice.
