In order to determine the best bike lock, we ordered the 27 toughest models we could discover. We sawed, cut and chopped through the locks and discovered that almost every lock can be defeated in less than a minute. Our recommendation after many hours of testing is the Kryptonite New-U Evolution Mini-7. It offers enough security advantages over other locks in this price range to prevent an everyday bike from becoming an easy target for thieves. This test comes from .

Update 18. 4. 2019: We added additional details about the latest version of our top recommendation, the Kryptonite New-U Evolution Mini-7. In addition, we evaluated revised versions of other wheel locks.

Update 9.3. 2020: The product recommendations and prices are still up to date.

Our top recommendation for a bicycle lock: Kryptonite New-U Evolution Mini-7 with loop cable

    Kryptonite New-U Evolution Mini-7

    With a double lockable, hardened 13 – mm bracket, one included cable and a free year of theft protection, the Kryptonite Evolution New-U Mini-7 is a good deterrent at a reasonable rate current price.

The Kryptonite New-U Evolution Mini-7 resists most attacks and shows weaknesses only in the fight against power tools. Right at the beginning of our tests, we recognized the great advantage of this lock over the competition: the hardened, 13 Millimeter thick stirrups can withstand bolt cutters, which will deter the majority of potential thieves.

With a length of just under 18 centimeters it has the ideal size for most applications: it is long enough to attach the bike and frame of most bikes to a fixed object. At the same time, it offers little space to open the lock with a pipe or a jack.

The latest version of the New-U Evolution Mini-7 has a modified bracket that makes turning (and thus removing) after cutting even more difficult.

The Kryptonite New-U Evolution Mini-7 uses a disc cylinder lock (“Disc Detainer”), which is much more difficult to crack than the cylinder locks (“Wafer Lock”), who use some other models – that discourages occasional thieves without special tools. The lock includes a cable with a length of 1.2 meters, for example to secure the front wheel, plus a free year Kryptonites anti-theft protection . In the event of theft, the guarantee replaces up to 2. 250 Euro and can be for 22 Euro (25 U.S. dollar) extend to five years. Important: You must have your lock within 30 days after purchase.

An even better bike lock: Kryptonite New York Fahgettaboudit Mini

    Kryptonite New York Fahgettaboudit Mini

    The Kryptonite New York Fahgettaboudit Mini is the safest lock we had in the test. However, with two kilograms it weighs significantly more than our top recommendation

The Kryptonite New York Fahgettaboudit Mini is the safest lock we have had in the test. However, with two kilograms, it weighs significantly more than our top recommendation. With its double locked, hardened, 18 Millimeter thick shackle held the Kryptonite New York Fahgettaboudit Mini better than any other lock Cutting attacks stood. Cutting through with the cutting disc took four times longer than with the top recommendation.

However, the weight is more than two kilograms. It is much more difficult than our top recommendation. But for those who live in an area with a high risk of theft, the New York Fahgettaboudit Mini is our recommendation.

Like our top recommendation, it uses a very secure disc cylinder lock. It's long enough to enclose the bike frame and the bike without appearing too bulky. Theft compensation from Kryptonite provides additional security for one year at the highest coverage level of 4. 500 Euro.

Also a bike lock recommendation: Kryptonite chain lock New York Fahgettaboudit

    Kryptonite chain lock New York Fahgettaboudit

    The Kryptonite New York Fahgettaboudit chain is suitable if you need a longer lock and the weight – five kilograms – is of little importance.

The Kryptonite chain lock New York Fahgettaboudit is one of the hardest chain locks that we had in the test. It is useful if you want to secure more than just the bike frame and the bike, if you have a cargo or electric bike, or if your favorite place to lock is a street lamp. In the test, we had other chain locks that were even more difficult to cut through, but they also cost significantly more. At this point, it is better to buy a second lock rather than a more expensive model.

The Fahgettaboudit chain lock has a length of a good meter and consists of hardened links with 14 millimeter material thickness. The chain lock is held together by a 15 Millimeters of Kryptonite New York Disc Lock – that should be everyone except the most determined thieves in Keep chess.

These are the best bike locks 2020 in the test

Why you can trust our test

I – Duncan Niederlitz – have been working since 2002 in the bicycle industry, both in the United States and abroad. I had many of the locks tested. I worked in stores that sold these bike locks and occasionally had to break them open. In addition to working in the bicycle industry and working on this guide, I have spent hundreds of hours researching, selling, using and testing these locks.

We contacted John Edgar Park , an experienced castle cracker and instructor with over 20 years of experience. We sat down to check all the locks we had received to check for weaknesses.

For additional information, we met with a group of locksmiths. We visited her at a meeting where the topic of cylinder locks was on the agenda. The meeting took place in an unremarkable building in an unmarked room, and everyone who gave a presentation used his Defcon – code name.

We also have Mark Podob from Metlab , a heat treatment and metallurgy consulting company. We were looking for explanations of how the different metals are hardened and to get an insight into the construction of our locks.

A note on our own behalf: We recommend three Locks from Kryptonite. We are aware that this selection can raise questions. But we think the data speaks for itself. I worked in a shop a decade ago when that Bic pen fiasco broke out (an expensive kryptonite lock could be opened with a ballpoint pen) and I demonstrated the problem on the local news channel. Equipped with these experiences and a great deal of skepticism regarding the claims of the lock manufacturer, we approached the comparison. For this we broke all locks and carefully analyzed the results.

So we selected the models for the test

We spent many hours researching all the locks of the big brands. We also visited trade fairs to discover new locks that are not yet commercially available. We also critically reviewed the statements in the previous version of this buying guide and started looking for well-rated bike locks from lesser-known brands.

Manufacturers offer dozens of locks in very similar ones Executions. However, with supposedly different security levels and proprietary rating systems, it can be difficult to decide which locks are comparable, other than to go blindly by price or to research the ratings of independent organizations that rate bike locks – including

ART in the Netherlands and Sold Secure in England. Unfortunately, these institutions use different rating scales, and not all lock manufacturers submit all their models for testing. And even though these independent laboratories publish an evaluation, they do not provide information on how this evaluation was created and which tests were carried out for it. That's why these tests gave us only a rough idea of ​​the security of the locks.

We decided that we would only get results if we ordered the most expensive lock from each manufacturer and attack with all available tools. This is the only way we can define at our own level what every manufacturer calls the highest possible level of security. In addition, we ordered the affordable locks from our previous test, as well as some more expensive locks from companies that had performed well in our first test round. We also processed this selection with our tools. Overall, we have for this test 27 locks examined and the following brands considered: ABUS, Altor, Artago, Blackburn, Hiplok, Knog, Kryptonite, Litelok, OnGuard , RockyMounts, Schlage and TiGr.

So we tested

For the previous version of this guide, we have the various rating systems of foundations such as ART and Sold Secure examined and spoken to professional bicycle thieves.

However, a direct comparison based on the different tests was difficult because they all judged independently. We also looked for on the internet after every bike lock test we could find and analyzed the procedure. Not a single review had tested as many locks in as many ways as we imagined. We were therefore aware that a comparative assessment based on the available data would not be possible – unless we would carry out the tests ourselves. So we did it.

But in order to test the selected locks as well as possible and to get a reliable recommendation basis, we also have to understand the tools that bicycle thieves use. That's why we've created a list of the most common tools that bike thieves use to go on their tour. The list is based on our experience in bike retail and from interviews with bike crackers. This list became the benchmark against which all locks in the test had to be measured in order to receive a recommendation from us.

The tools

Lockpick: The lock pick is the smallest, quietest and most portable tools that can be used on the thief tour. However, it also requires the most skill in action.

Different lock types require different tools and represent different levels of difficulty. But as soon as a thief has the necessary skills and the right tools, he can easily open a learned lock. The challenge is not so much the opening itself as the search for a bike with the right lock type.

Wire cutter: Thieves carry out a large number of bicycle thefts (possibly most of them) with a cable cutter. The cable cutter is easy to carry in a bag, quiet to use and easy to steal if you don't already have one. The cable cutter is so effective because many bicycles are only locked with a braided steel cable and a padlock or a simple cable lock. These methods offer the least security and should only be used as an accessory lock in most situations. A good one Cable cutter can cut these locks in one operation, with a simple cable cutter it takes several cuts.

hacksaw : The hacksaw works quietly and relatively quickly through an unhardened lock. Most chains from the hardware store, cheap padlocks and cable locks can be defeated with a hacksaw. The main disadvantages from a thief's perspective are: Sawing thick locks is time consuming, sawing through a cable can get caught and physical effort is required. However, the hacksaw is a very cheap, easy to carry and easy to hide tool.

Bolt cutter : Since so many bike thefts are not reported, it is difficult to collect accurate data on how many bicycle thefts are committed each year and, most importantly, how all these thefts are carried out. However, from my experience I have had in stores over the years, I have heard hundreds of stories about stolen bicycles and seen many locks cut, and most of them (cut cable locks not counted) were cut open with a bolt cutter.

Bolt cutters can be quite small, usually 45 to 60 centimeters long. They cut quickly through a lock, are cheap, portable and easy to hide. They don't work with every lock, but for those with whom they work, it's a quick cut. As soon as a thief knows which locks are suitable for the bolt cutter, it is again just a question of finding a target lock and bicycle.

Rechargeable drill: This is a rarer tool for bike thieves as it only works well with a few types of locks, and most of them are easier to use with other methods as well defeat. Nevertheless, the popularity of this tool is increasing, which is due to the increasing spread of folding locks lies. Cordless drills are particularly popular against this type.

Angle grinder : A thief With a battery-powered angle grinder, every lock defeats when it has enough time. For the thief, the biggest disadvantage is the noise and sparks that the device emits when cutting the hardened steel. In the past, cordless angle grinders did not have enough power for this purpose, but battery technology is now so advanced that it works just as well as its wired counterparts. It's hard to miss an angle grinder in action, but a thief who goes bold enough and can mask the noise is likely to be successful in stealing the bike.

We didn't maltreat the locks with a jack. For this attack to be successful, the Jack fit into the bracket of the bicycle lock. In other words, if you choose a bike lock with a shackle that offers little unused space, a thief has no chance of getting the jack in position.

After we had put our tools together, we had to decide how we could evaluate the locks based on the individual tests. We believe that every lock is only as good as its weakest part. That's why we rated a lock the lower, the quieter and faster it could be opened, regardless of how it performed in other categories.

In the simplest method, we checked whether the locks could be opened with a lock pick (some could be opened). Then we started the bolt cutters (which mostly succeeded), used the hacksaw (which opened all the locks), and used the drill (which could also open each lock). Last but not least, an inexpensive angle grinder was used and the locks were cut faster than expected.

After we finished all tests, we have the locks for their security and their price s classified. Then we took into account features such as durability, weight, portability and ease of use.

The test methods: crack locks

We contacted John Edgar Park , a passionate castle cracker and instructor with over 20 years of experience, and checked together all the locks received. After a brief visual inspection and the use of his lockpicks, Park immediately found out how each mechanism works and how the easiest way to defeat each lock.

He taught me how to break a lock. With a model I succeeded in less than 30 seconds after I watched John do it twice and guide me through the process once. It is one simple hard work that requires little skill and simple tools. A few metal parts from the wiper of a car are enough. And I always thought that MacGyver was just entertainment.

For additional information, we met with a group of locksmiths. We visited her at a meeting where the topic of cylinder locks was on the agenda. The meeting took place in an unremarkable building in an unmarked room.

Our most important finding, among many other information, was that even the simpler cylinder locks, that we brought with us were very difficult to crack. Nobody at the meeting had the right tool to fit in the smaller keyways that most bike locks use. Therefore, we are confident that disc cylinder locks are safe against most thieves.

The test methods: bolt cutters

The next test for the locks is the bolt cutter. This tool is cheap to buy in any hardware store. In the event of theft, it usually only makes a noise if it is too late and the lock breaks apart. They could stand six meters from their bike and will not hear the use of the bolt cutter. We chose two models for our tests, the 24 – inch HDX from Home Depot and the 36 – Tekton model 3421.

Some of the locks we tested stated that they were particularly resistant. In the end, we got almost all locks cut with the bolt cutter, be it due to construction problems, thinner chain links, softer metals or differences in the hardening process. The easiest to cut padlocks seemed only to be case-hardened and were none other subjected to heat treatment process .

Mark Podob from heat treatment Company Metlab describes the relationship as follows: “The advantage of case hardening over hardening is that it offers a hard surface to a certain depth and enables the use of a cheaper low-carbon steel for the temple material. On the other hand, the penetration of the remaining material quickly as soon as the housing is penetrated. “

The test methods: hacksaw

We did not expect any extraordinary results from the test with the hacksaw, since even locks with a simply hardened outer material can withstand such a tool. However, the locks from Altor- and TiGr ​​are made of titanium, a resistant but not very hard material. This was confirmed by our test with the hacksaw: with it we needed less than 30 seconds to cut through a lock, clamped in a vice. The use of the vice probably led to a shorter cutting time, but experienced thieves know tricks with which they can fix the lock (support with cable ties or by leaning against the bike). The RockyMounts lock we tested is made of stainless steel, which appeared to be unhardened to our eyes. Despite the large bow diameter, our hacksaw cut into only 90 seconds through the lock.

We were able to lock RockyMounts Compton Large, Altor 560 Cut G and TiGr ​​Mini with a hacksaw. Wirecutter / Duncan Niederlitz

The test methods: cordless drill

A cordless drill is louder than a bolt cutter in use, but is hardly noticeable on a busy street. It is also handy, attracts less attention than the bolt cutter and makes less noise than angle grinders. For the test we used the 12 V Milwaukee Fuel, which even fits in a jacket pocket.

The castles Altor 560 G and ABUS Bordo Granit X-Plus was able to quickly defeat the cordless drill. The hinges on these models turned out to be the weakest part. The connecting bolts that held the links together in these two hinged locks were unhardened and could therefore be pierced quickly.

The test methods: angle grinder

The last test was the angle grinder. It was clear to us that no lock from the 7th 00 0 revolutions per minute could withstand the fast cutting disc – the only question was how long it would take. After many anecdotes from customers, reading marketing literature and playing YouTube videos, we expected that cutting through the steel would take us at least a minute.

For the angle grinder we loaded all the available batteries, brewed extra coffee and prepared ourselves mentally for the work ahead. Then it took 14 seconds until the first lock was cut. 15 seconds for the next one. Some locks even fell under the 10 – seconds mark. And even the strongest locks only performed 30 seconds of resistance.

Wirecutter / Duncan Niederlitz

We learned that no lock could withstand a modern cordless angle grinder for more than a minute – even a chain or a double-locked bracket did not pose any significant obstacles. Admittedly, we carried out all these tests under ideal conditions in a vice, in order to ensure the same conditions for all locks to accomplish. But even after we tested some locks in unfavorable external conditions, we only noticed a slight increase in time.

A few seconds of construction site noise in a busy city not uncommon. And even if it's obvious that a bike is stolen, it hardly attracts attention, like this video shows .

So why lock the bike at all? That is the question that many people ask themselves when they realize that a bike start-up hardly attracts any attention from passers-by and what potential modern electrical tools offer. Why bother to secure a bike with an expensive lock when it only takes an extra minute for a thief? It's also about reducing the risk of theft. If you ride a less expensive bike and can lock it with a better lock in a safer place, the likelihood of it falling victim to a thief decreases.

Detailed test: Kryptonite New-U Evolution Mini-7 with loop cable

The Kryptonite New-U Evolution Mini-7 offers a variety of features to prevent theft – an even better configuration offers only twice as expensive or twice as much heavy locks. It has a hardened, double-locked shackle, which simpler locks do not have, and is equipped with a secure disc cylinder lock.

The Kryptonite lock is supplied with a 1.2 meter cable and a free year theft protection. This model is slightly more expensive than the Kryptonite Series 2. But the additional costs will decrease if you plan anyway Buy anti-theft protection from Kryptonite – our top recommendation is one year of protection up to a damage level of 2.2. 50 Euro already included (registration within 30 days after purchase required).

The Kryptonite Evolution New-U Mini-7 is a good deterrent at a reasonable price. It offers a double lockable, hardened 13 – mm bracket, brings an additional safety cable with and Year free theft protection. Wirecutter / Kyle Fitzgerald

The greatest added value is difficult to see at first glance. Instead of just using a case-hardened shackle (the large U-shaped loop from which the U-locks take their name), the Evolution series uses a harder steel shackle and a hardening process that is not technically “hardened”, but in ours Tests endured more damage than other locks for the same price. While we already have smaller locks with a 24 – the bolt cutters could break through, the New-U Evolution Mini-7 even held our 36 – inch cutters stood and survived with just a few small scratches.

The bracket of the Kryptonite New-U Evolution Mini-7 is opened locks a non-blocking knee on both sides instead of on one side to have foot. The advantage is that a thief would most likely have to make two cuts with a power tool to open the bracket. And after making these cuts, the thief would have to twist off the bracket; In addition, Kryptonite has attached a small cutout at each end of the New U series, which makes it all the more difficult to turn it off.

A practical LED light is included in the key. Wirecutter / Kyle Fitzgerald

The Kryptonite New- U Evolution Mini-7 also uses a particularly secure disc cylinder lock (“disc detector”). This type of lock is very tough and requires special tools, patience and skill to crack it. After consulting several experts in lockpicking, we came to the conclusion that this type of lock offers a high level of protection against opening on the road.

The New-U Evolution Mini 7 has a protective rubber layer on all main parts that helps prevent scratches on the bike frame. The Kryptonite New-U Evolution Mini-7 is available in different sizes. We think that the 18 – Centimeter variant is ideal for most people. If you have a bike with large tires and want to secure both wheels, this model may not be long enough to fit over the tire and frame. In this case, special axles with theft protection are a solution. Alternatively, Kryptonite offers the Evolution lock in a larger size, but then without the additional security cable.

Weaknesses, but not deal breakers

We believe that the hard grip and the difficulty of squeezing a jack into a properly locked New-U Evolution Mini-7 are more likely to thwart attacks than with any other lock in this price range. But if you live in a risk area or are looking for more protection, we recommend the stronger Kryptonite New York Fahgettaboudi.

The scope of delivery of the Kryptonite New-U Evolution Mini-7 includes a frame bracket which we consider one of the better of its kind. But that doesn't mean much. Bicycle mechanics don't like U-locks because their brackets are always in an unfavorable position on the frame and because they loosen over time. We therefore recommend, as far as possible, to transport the lock on the luggage rack or a basket.

Detailed test: Kryptonite New York Fahgettaboudit Mini

The Kryptonite New York Fahgettaboudit Mini is a workhorse. You will not find any nice gimmicks on it, but a lot of metal alone – two kilograms to be exact – that promises a high level of security. This lock uses a hardened, double locking shackle and additional metal in the crossbar for even more security. The 18 Millimeter-thick stirrups have a cross-sectional area that is twice as large compared to our top recommendation. A thief has to spend more than twice the time to cut.

The Kryptonite New York Fahgettaboudit Mini is the safest lock we've had in the test. However, it weighs significantly more than our top recommendation. Wirecutter / Kyle Fitzgerald

The only significant disadvantages This lock compared to our top recommendation consist in price and weight. It costs twice as much and weighs twice as much – but also offers greater security. Our tests confirm the connection: the heavier the lock (and the more hardened metal was used), the more secure.

The New York Fahgettaboudit Mini contains no fastening parts with which You can attach the lock to the frame (although we doubt that a bracket would stay in place at this weight). Also, an additional loop cable like our top recommendation is not included in the scope of delivery.

Detailed test: Kryptonite chain lock New York Fahgettaboudit

Sometimes you just need a chain lock. We think that Kryptonite New York Fahgettaboudit offers the best price-performance ratio when it comes to a lock with extra security. The chain consists of 14 millimeters through hardened links and is both in a standard length of 99 centimeters as well as a huge 1.5 meter version. The chain is made by Kryptonites 15 – mm- “New York” disc cylinder lock with a double locking shackle connected. The theft protection is free in the first year and offers a maximum contribution margin of 4. 500 Euro (registration within 30 days after purchase required)

The Kryptonite chain lock New York Fahgettaboudit is suitable if you need a longer lock and the weight – five kilograms – is of little importance. Wirecutter / Kyle Fitzgerald

During the endurance test with the angle grinder we were able to use the chain lock Cut through a little faster than our top U-lock recommendation New York Fahgettaboudit Mini. Nevertheless, we found the overall security level to be on an equal footing. Another advantage of the chain lock is the more practical length.

There were two models under the chain locks that we needed longer to break open: the Kryptonite New York Legend and the Artago 69 T 100 E. The round 50 Percent longer resistance time you buy with a round 50 percent more expensive price.

If you attach particular importance to security, we recommend the purchase of two locks instead of a particularly expensive lock.

Care and Maintenance

Locks are well equipped to withstand rough handling, from rain to snow to road dirt. Fortunately, the maintenance of the locks we have chosen is very easy. Open your lock, clean it of all dirt that you can reach with a cloth. Spray some degreaser into the lock if it feels sticky. Then put some dry lubricant in the lock and turn the key a few times in the lock. Kryptonite, for example, offers a Step-by-step instructions on his website.

More bike locks in the test

Kryptonite Evolution Mini-7 : Our previous top recommendation is slowly becoming commercially available due to our current top recommendation replaced. The main difference to the more modern Kryptonite New-U Evolution Mini-7 is that the bracket is only locked on one side.

Our previous top recommendation with articulated bracket, the Kryptonite Evolution Mini-7. Wirecutter / Kyle Fitzgerald

Kryptonite bike lock KryptoLok : Formerly known as Series 2, this model uses a disc cylinder lock. You can optionally add the Kryptonite theft protection. Kryptonite also offers this lock in a New-U version with an improved shackle design, but that doesn't solve the biggest problem of this model: bolt cutters can cut through it. We believe that spending more on a hardened lock like the New-U Evolution is worth the extra security and will put off a lot of the potential thieves.

Kryptonite chain lock KryptoLok Series 2 : For the price this is a great chain lock, even if it is almost half a kilogram heavy than our first choice. For this reason, we actually prefer a U-lock, but if it should be a chain lock, this is a good choice. The main disadvantage is that a thief can open it with a bolt cutter. In our test, this disadvantage turned out to be less serious than expected, since the square shape of the 9-millimeter chain kept our bolt cutter slipping off.

Kryptonite New York Legend chain with padlock : This was the strongest chain that we tested, but due to its weight and design you don't want to move the lock around. It is primarily suitable for stationary use in one place.

Kryptonite chain lock New York Chain : This chain is lighter and cheaper than the New York Fahgettaboudit chain and offers less security. There are no real vulnerabilities, but if you are looking for protection at this level of security, the even better Fahgettaboudit chain makes more sense.

In general, OnGuard's locks have been in ours Tests proven. The time it took us to cut through was very similar to our top recommendations. We see the biggest problem with the OnGuard locks, including the OnGuard Brute STD , OnGuard Beast 8016 and OnGuard Pitbull STD , in the locking mechanism itself, as it is particularly easy to crack. Neither fancy tools nor advanced skills are required.

Abus folding lock Bordo Granit X-Plus : The design of this lock and the mounting bracket make it by far the most beautiful lock, since it can be folded up very compactly and can be transported in the frame housing without rattling. However, it's not a high-security lock as claimed: a thief can easily defeat it by drilling out the uncured pins that hold the limbs together. With enough patience, I was also able to unfold the limbs by incorporating large bolt cutters into the joints, such as the YouTube channel House of Chain on a smaller version of the Bordo folding lock in this video shows . The performance is okay for use in an area with low crime, but the price is too high in relation to the level of protection.

ABUS Bordo Alarm 6000 a : This updated version of the ABUS folding lock has the same advantages and shortcomings, with the added annoyance of the constant beeping with every movement.

Abus Granit X-Plus : This U-lock is one of the lightest of its size. However, we were also able to cut it much faster than our “even better recommendation, the New York Fahgettaboudit Mini.

Abus U-lock 40 U-mini : At first we thought this lock would be a candidate for our top recommendation because of the design of the evolution very similar, but the top recommendation was out of the question after we were able to cut it open with a bolt cutter, it was one of the easiest locks to cut through and ranked on a par with Kryptonite Se Ries 2 standard U-lock.

Hiplok Bicycle Lock Gold : The design of this chain lock allows you to wear the chain around your waist without locking it. (You should never wear them in a locked state – keys are lost, locks get stuck, accidents happen, and paramedics need to be able to easily remove the lock in an emergency.) This design is a nice feature, but a few zippers or one Velcro can give almost any chain a similar functionality. In our tests, this lock was cut quickly, but the real problem arose in the bolt cutter test, which we were able to carry out too quickly.

Hiplok D U-lock : The lock has a double locking bracket and is hardened. We couldn't cut it with the bolt cutter. It uses a better lock than the OnGuard models. A thief can crack it with simpler tools, but it seemed to us more secure than any of the OnGuard locks. Despite the double locking bracket, it shows enough freedom of movement after just one cut, enough for a thief to remove it from the bike frame.

RockyMounts Compton Large : This Lock with 18 Millimeter thick bracket was one of the heaviest in the test. It is made of stainless steel, which is harder than mild steel, but definitely softer than hardened steel. The test showed the material difference because we were able to cut the Compton Large twice as quickly as the locks from Artago and Kryptonit, which also have a 18 – use mm bracket. In addition, this lock is the least ergonomic in the test, as the sharp steel edges without rubber protection show.

Knog Strongman : We really liked this little castle. It is almost completely surrounded by a thick silicone coating, which makes it scratch-proof and almost noiseless during transport. However, there is no recommendation from us. In the test, a cut through the temple resulted in a comparatively large distance between the two halves of the temple. Many reviews on Amazon criticize the locking mechanism, which can corrode and become increasingly difficult to open over time.

Litelok Gold Bicycle Lock : We found the strap of this lock extremely difficult to cut without power tools. Placing the cables on a flat metal band is a smart idea and can very well slow down these types of attacks, although someone with enough patience could make the breakthrough. The big weak point of this lock was revealed when attacking with a small bolt cutter against the locking mechanism (this is where most thieves start with cable locks): The entire mechanism spreads open and reveals the thin metal strips that hold a thin rod that holds the Bolt of the castle. A second cut through the bar and the lock fell into its individual parts.

Outlook: These new bike locks are coming up

The Internet of Things does not stop at bicycle locks. Manufacturers are trying to improve their locks by connecting their products to the Internet. This is a challenging goal, because in contrast to a refrigerator at home, the networked lock also needs a connection to the Internet on the go. This can be done either via the cell phone network (which causes additional costs) or via Bluetooth (which has a limited range).

Nevertheless, we hope to test some of the announced smart bike locks soon, including the electronic bike lock Lattis Ellipse , a frame lock called LINKA , the ABUS 770 a SmartX and that GoLock .
