Brand: Kryptonite

👤The bike was stolen from the locked garage. There were no signs of metal on the ground that it was difficult to remove. Even though I registered and did everything correctly, they did not honor their 'warranty'. The bicycle was expensive and it was easy to cut the lock. An awful company. I will never do business with them again.

👤I like to buy products from Kryptonite locks. I use this lock for my bike. As I park in the city and see bike parts being stolen, I wanted a nice lock set. I got this lock because I want to secure my bike better. I wanted to store it on my bike while I commute. This is the best lock in the world. The cloth covering protects my bike from being scratched. It is heavy and bulky and it is difficult to get the lock back into the holder after folding it up.

👤It's a simple lock. It's good for the price. It's not as thick as you can find. It says on the label that it is not the safest. The key seems to be turning without a problem. I returned it because it was longer than I needed.

👤I recommend using this lock as an addition to another lock because it is a very strong lock. If a thief wants your bike, he will find a way to get it, but this lock will make the process much harder. I think that Kryptonite makes very good locks and at reasonable prices.

👤I had to send it back because it wasn't what I was looking for, but it was a great solution if you need a serious locking system.

👤Heavy and clumsy. My bike is safe with this chain lock. Half the protection comes from the way it looks.

👤The lock is good for the price. It has a metal rod that is a bit thicker than a chain. The lock system is nice. The length is sufficient for a normal lock up. I am happy with this unit at the moment.

👤I was worried about interference from riding because this lock was large and stuck out around the frame.

👤The lock is strong. The sheer weight of it at over 1 kilo makes a big difference on an 8 kilo bike, but that's to be expected with any decent lock, and I really wanted a Sold Secure Silver lock. It folds up nicely on my bike and I have never had any issues with it moving in the holder.

👤The lock is good. The key can be a little stiff and not always in place. Generally, it is pretty good. Trying to put the lock in its carry case is very difficult. I don't know who designed it, but if you are reading this, please try and use it. Maybe you should go back to school or change careers.

👤It's very handy as it fits on a bike.

👤The lock is sturdy and good. The bars and the skeet protect your bike from damage. The key hole cover is a nice touch, but I'm not sure why they had it slide both directions. One thing I don't like about the lock is the fact that you have to turn the key to get into it. The lock is heavy. You can feel it on the bike. There is a The carrying assembly is a problem. The thick grey strap is too small for the chains to fit easily. It takes around 5 minutes to put them in when they're not on the bike. You'll break the strap when it's on the bike. I've removed the strap by sliding it off the body of the carrier and will use the straps that hold the carrier to the bike's tube to hold the lock in the carrier. Comment or find the review helpful. I will post a video on how I removed the strap.

👤I watched as someone tried to steal my bike through my window. Cut the garbage lock in a second. I saw it through my window. I uploaded the pictures after the incident. The scum bags were caught by the police. Don't buy.

👤After 6 months of using the lock and chain, my radRover is still safe. This setup has a huge plus right of that bat. My bike is not very low key. A huge fat tire e-bike is drawing attention. I use it to commute to and from work. I must be locked up where I live. The chain and lock work with the size of my bike, while also being able to lock into unique places your U-lock wouldn't work. Sometimes I lock myself to railings and columns. The weight is a negative, but it's not an issue with an e-bike. I don't recommend carrying it in your backpack. It's just to be uncomfortable. Either chain to your bike or leave it where you want it to be. Its not leaving. If you are not careful, you may ding up your bike. Most of the chain is covered with a fabric, but the ends are bare metal. There is a I really like this setup. I would definitely recommend! They offer theft protection with a lock, so I take one star off. I would like to have signed up. They gave me an invalid key. I couldn't continue with the registration because there was no option on the website. If this happens, they have an option. I was out of luck after 3 emails and no response with the link, the only 30 day after purchase was kicked. If I could leave a 4.5 review, I would take anything away from the lock. I thought it was an issue.

👤I'm on my second. My neighbors tell me that it took the cops 30 minutes to get through the chain after they seized my bike. There is a rust stain on the sidewalk one year later. Great chain!

👤The pictures don't show how heavy this chain is. If you're carrying a lot of other weight on the bike, it's more than 15 pounds. There is a I have to get the links through the spokes on my tire. I think I might have gotten the next size down of chain if I had to choose again. There is a When I need to lock up my bike at the farmers market, the chain gives me a piece of mind. I live in a high theft area, and I know that a chain and lock won't be 100% successful against a determined thief. The goal is to make my bike harder to steal than the bike parked next to it.

👤I bought this to store my bike in a garage. The main threat for this garage is that a driver might forget to close the garage door after driving away and a passerby could enter. I wanted the bike to be more annoying to steal than the bike next to it. I bought this chain for the purpose of keeping a passer-by from riding away on the bike. There are no fixed points to secure a bike. The links in the chain are thick and it did not work for this purpose. They barely fit between the spokes. I was worried that the weight of the chain would warp the spokes, because it was hard to get the chain in there. It was difficult to use the chain without being loud. The chain would fall or part of the U-lock would fall, and it was disruptive to neighbors. I will probably buy a U-lock for my original purpose after returning the chain.

👤If you live in New York City, stop reading this review and buy the heaviest chain you can find, or try the Faghettaboudit. Keep reading if you're not sure. There is a If I wanted to protect my new bike, I had to change the lock on my last bike. I decided that the only way to get a bike lock was with Kryptonite. I only had to decide how much protection I needed, because of the name of the bike locks and the customer service. If you like me, and want to figure out what suits you best, consider the following: Cable Locks. Any person with a pair of wire cutting pliers can chew through a cable lock. There is no need for power tools. Don't take the risk unless you live in a theft-free area. The mounting brackets that come with any U-lock make it perfect for a commuter bike. U-Locks are usually in 4x9, 3.25x7, and 4x11.5. The smaller the lock, the more secure it is. The longer it is, the harder it is to lock onto bike racks. Multiple bikes can be locked up with larger locks. The flexibility of reaching around larger or oddly shaped objects is something that chain locks offer. You can lock up several bikes with a chain, and you can lock up trees with a chain. The lightest chains are comparable to the toughest U-locks, which is the greatest disadvantage. You have to carry the chain locks around with you on your bike. I made my decision based on the criteria. I live on a college campus and have a bike rack or fence. There is a My lock needs to be lightweight because I frequently go for long bike rides. There is a I don't want to worry about dinging my bike frame with a lock if I don't have a backpack. There is a My lock must be intimidating because of the high rate of theft here. There is a Prytonite has theft insurance with their locks. I kept my bill of sale so that I could apply the protection to my bike. There is a The Evolution Mini-7 was the best compromise for my needs. It is one of the smallest U-locks available, but still has a tough 13mm shackle. The lock mounts easily to my frame, and is lighter than any chain lock I could find. I have had no issues with a sticky tumbler and the rubber coated shackle doesn't scratch my bike or freeze my hands in the cold. I like the fact that it comes with a 4 ft cable, because I can loop it through my front wheel if I ever lock up. This lock has a $2000 theft insurance package from Kryptonite. I could never sell my bike for more than a few hundred dollars. The insurance will cover my bike if it's ever stolen. The Evolution Mini is light, portable, and insured.

👤I use it every day in a high crime area and no one has been able to steal my bike yet, even though they stole some lights and tried to steal the front wheel. The Road Warrior of bike locks is a handy club that can be used to punish attackers. I wouldn't need to sling it so hard if the feature was built into this.

4. Kryptonite Evolution Bicycle FlexFrame 11 5 Inch

Max Performance Steel Shackle Resists Hand Tools, Bolt Cutters, and Leverage Attacks are 14mm hard ended. The dimensions are 4 x 11. If you lose your first 2 keys, you will be able to get a free second one. There is an anti-theft protection offer. Reimbursement for 1 year is up to $3, 000.

Brand: Kryptonite

👤The bike lock is the worst I have ever had. Great locks were made from Kryptonite. They have changed the lock mechanism, which has a flimsy key that bends very easily. I had a lock that would not open for days until it randomly unlocked every once in awhile. I had to take public transportation back to my house every time my bike got stuck because I couldn't open the lock. There is no return option here, so will have to contact the person directly.

👤I have to give this product a star to write a review. It doesn't deserve much. Many reviewers commented on the faulty key lock mechanism, but many had no issues. It's not good if you have a lock on your bike that won't open. I don't understand why a company with a good reputation would continue to sell a faulty product. Very disappointing.

👤I have had this lock for about 6 months now and it is already breaking, but it works for the first few months. The key hole is stuck so that the key can't turn. It takes an extra 10 minutes to lock my bike up every time it jams. The lock on my fiancé's bike is the same one that I have. If you want it to last more than a few months, save yourself the frustration.

👤I had this product for a month. Next to my car key is where to store the hey. The key isn't working today. If the backup key doesn't work, I'll use a hacksaw. I'll never buy another lock like this one.

👤I sent a picture of the damage to the person who asked for it. They sent me a new lock and a label to send the damaged one back. During the Covid-Crazy! These days, first rate service is nice. The screw was tightened with the supplied wrench. On my first ride with it mounted, the lock was rubbed by the back tire and the finish on the shackle was damaged. I'll see what they say. This lock is very large. If that matters to you, it's heavy. There is a The key and bolt operation is smooth. I'm scared the lock is heavy enough to break if I hit a curb, so the mount is the only con. Time will tell. It would be nice if the mount was designed to be moved, as it is when you cut the rubber and strap and you're stuck with that size. There is a 5 stars for the lock!

👤I bought it because of the reasonable insurance the company offers. The lock is strong but can be broken. I had trouble locking the bottom piece to the U at 1st because I had to push it all the way together or it wouldn't lock. The 2 pieces can't go all the way together if the rubber o rings are blocking them. You can always move them higher up the shaft. If you don't want to use the holder, you can remove the rubber o ring by the 1st.

3-year warranty applies to U lock for US, CA, UK, EU Cyclists, 90-day money back policy, and online customer service. If you don't like it, you will get a full refund.

Up to $3,000 Reimbursement for 1 Year is included in the Anti-Theft Protection Offer.

Brand: Kryptonite

👤I bought this lock because it was reviewed by Wirecutter. There is a The lock was very inconvenient to use. The key wouldn't budge. The lock would get stuck as well. My bike was stolen after only 6 months of using this lock. Their anti-theft protection offer is not real. You have to send a picture of the broken lock to make a claim. What idiot thief would leave behind the broken lock with their fingerprints all over it at the crime scene? I made a police report. I haven't heard from the company in a month.

👤After our son's Trek Marlin 6 was stolen from the bike parking at his high school, we upgraded the lock to protect his new replacement. For almost a week, it was protected. The lock on his bike was destroyed when it was stolen from the high school. They all fall to power tools regardless of which lock you purchase. Don't be foolish. No lock will stop them if the bike is unattended. The lesson was brought to you by a parent who wondered how his child could get to school on a bike.

👤The lock should be recalled. It seems like it works well when you test it over and over indoors, but as soon as I try to use it to lock my bike outside, it doesn't seem right. Forget it! I can't get the key to turn for the rest of my life. Is it because I can't push the bottom of the lock all the way? It got worse over the 3 times I tried to use it, and I had to carry my bike inside my gym because I couldn't lock it up. The lock is limited to use with a bike rack, which is hard to find in a shopping center. It is easier to lock up a street post with a folding lock. I was able to lock this to the street sign post a few times, but it took me a long time to get my bike aligned right to the post, even though my mtn bike is the smallest size. Was so angry.

👤Had to return it. It was difficult to lock the lock. I'm talking about the mechanism. We have two things. Both keys were not properly ground after cutting. It was difficult to insert the key and turn it. I was unable to secure my bike because the lock wouldn't lock. I tried to get it to work with a nasty injury to my thumb. Thank you Amazon, no problems returning it. I bought a folding lock from the company.

👤The lock I received from Amazon was difficult to operate, but it was exactly what I needed. I wonder if they have all the bugs out of the lock yet. I could see that the back layers of the cylinder were not in line with the outer layers when the key was only half-way. I don't know how many layers there are, but since the key only goes in half-way there was no way to turn the back layers so they would line up with the outer layers. After turning the key back and forth for about ten minutes, the layers lined up and the key went in all the way. I had to ask for a replacement for the key after it turned in the cylinder, as it continued to meet resistance. I wouldn't trust the lock I received to operate. The keys are very easy to open in the cylinders. I wonder if I have a bad lock or if the new design will cause problems. The black housing that rotates to cover the keyhole was difficult to operate. The plastic was visible under the edge of the housing. As I turned the cover back and forth, I saw more and more shavings working their way out of the keyhole. I pulled them out and the cover began to move. All of the hair in the attached photo came from under the lock. The cylinder is difficult to turn and the layers of the cylinder sometimes get out of line as the key is inserted or removed, if any of the shavings found their way down into the cylinder while the lock was being assembled or when it was bounced around during shipping. There is a further update. I looked at the lock again while waiting for the replacement lock. The design of the metal body of the lock has a narrow split that extends from the keyhole to the black plastic end, according to a flashlight look at the lock. I can't see how far the split extends, but I can guess if the lock body has sharp edges or if the rotating black cover is shaped too tightly around the lock body. The cylinder operation I encountered could be caused by any of the shavings working their way into the cylinder. One comment asked if the replacement lock had the same problem. The replacement lock has worked well so far.

6. Kryptonite Kryptolock Mini 7 Bicycle 7 Inch

Kryptonite Kryptolock Mini 7 Bicycle 7 Inch

There are 12. 7mm hardended performance steel shackle resists hand tools. The dimensions are 25" x 7". If you lose your first 2 keys, you will be able to get a free second one. Up to $1, 750 Reimbursement is offered for anti-theft protection.

Brand: Kryptonite

👤If you ride a 17 inch frame bike, it cannot be mounted anywhere without hitting your legs, that's why the lock is useless. The lock cannot be discharged if I try to lower the seat on the post. I wasted my gift card on this purchase.

👤I paid a lot for this lock because I wanted something that would look cool on my bike, and something that would be easy to use. There is a I thought there was no more lock hanging off my belt loop. I thought differently. I only used this lock on city roads for three weeks and the mounting brackets have come apart. This isn't good enough for a $50 lock. I will not wait past the return date to give the seller a chance to address the issue.

👤It's hard to believe this lock doesn't have the highest security rating. It's heavy and thick and the locking mechanism means that even if you cut through it, the pieces will stay locked in place, meaning that a bike can be stolen. When attaching it to a bike frame, the clip on the lock itself can be moved through the air, and the brackets which attach to the bike have a fabric strap which can wrap tightly around even awkwardly shaped frame bars. The lock can be fitted just about anywhere on the bike frame that's safe, without taking up the space needed for a water bottle, because the clip for the lock can be changed through a 180 degree rotation. Highly recommended product.

👤My bike was stolen from my car. They cut the wire rope lock with a cutter and rode off. It will hopefully deter someone from riding off easily when installed between the frame and back tire. I would have to take the bike and grind the lock off. If you register the lock and enroll in their service, they will reimburse you.

👤The product is high quality and works well. The best entry level lock on the market that comes with an attachment to hold your lock while you are biking is the Kryptonite lock. Keys are high quality and don't get stuck or bend easily. The lock holder has a rubber strap so it doesn't scratch your frame. If your bike is stolen, you can register for the insurance program where they will pay you up to $2000. They will give you free keys as long as you register them. If I had 10 bikes, the company would buy 10. After using for about 2 weeks, I would recommend adjusting the holder every week to make sure the lock doesn't get in your way while riding.

👤My husband decided to take his chances with a fancy bike after he bought it. It didn't. I don't know how, but the bike didn't budge from the bike rack at his place of employment. There is a I am a little crazy. I surprised him with a lock for a fancy bike because he was constantly concerned. We have had a bike lock for three months and it has not been stolen. It is easy to use and locks. You would need a lot of bolt cutter to remove it. Will buy another for my bike.

7. Kryptonite KryptoLok 13mm Bicycle Disc

Kryptonite KryptoLok 13mm Bicycle Disc

13mm hardened Performance steel. A disc-style cylinder has high security. A reinforced sleeve is over the cylinder. The design of the foot makes it easy to use. The cylinder is protected from dirt and grime by a rotating dustcover. The keys are made of "I" steel. Product dimensions are 42mm x 49mm. Product weight is 1.35 lbs. x 0.61 lbs.

Brand: Kryptonite

👤I bought this to use as a wheel lock for my moped. It doesn't fit my disc brake, but it does fit the wheel spokes. The wheel is too small to stop it from turning. This is risky because sometimes there isn't a good fixed object to tie to. It's not the fault of the lock, that's my purchase. The lock is hard to close and my down rating is because of that. You have to pull the key out after closing it. I struggle with it almost every time because I have to bend over between the ground and a hard spot and hold the looped cable in place. The mechanism of the regular sized series 2 is better than the small one.

👤After a pair of thieves tried to steal my bike, this lock helped. It was hooked. The NYC chain is solid. They tried to drill out the hole. The lock works despite the failed attempt. Awesome.

👤Over the top in construction. It should be the first item purchased when secure.

👤Trying to get a replacement. It keeps crashing.

👤The god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of light, the god of Nothing more needs to be said.

👤Not tried or tested. They don't try to steal my bike. The movie was good.

👤It is one of the best locks out there, but it can be a bear to close it.

👤This little lock is no exception. It is small so make sure you check the dimensions before buying. It's easier to operate one-handed with the permanently hinged end of the shackle. Make sure you use this as part of a more comprehensive security system, as it is not enough alone to protect against moderate lock attacks.

👤Articolo arrivato. Ottimo oggetto, non credo serva dilungarsi oltre. Un giusto prezzo ad oltretutto. Assolutamente consigliato. Un unico avvertimento, se usato per chiudere una moto. Asole della corona di diverse moto. La lunghezza della "U" per contro. A tale da poter essere usato su qualsiasi misura e tipologia di disco anteriore.

👤Come bloccadisco per una moto senza. I dischi forati, perfetto, robusto, e interamente ricoperto da materiale plastico gommoso per evitare. Trovo ottimo il copriserratura, in pioggia o polvere. Robusto e piccolo lo user anche per legare.

👤A facile utilizzo is what the Bloccadisco solido is. I fatto ha una parte rimane sempre attaccata e quindi. Se avuto anche il cavetto per ricordarsi di toglierlo.

The technology is compact and versatile. The 18mm Hardended Max Performance Steel Shackle Resists Hand Tools. The dimensions are 25" x 6". If you lose your first 2 keys, you will be able to get a free second one. Reimbursement for 1 year is included in the anti-theft protection offer.

Brand: Kryptonite

👤Someone tried to steal my bike, so I beat them with my lock. It is durable.

👤If you didn't register your New York Fahgettaboudit lock within 15 days of purchase, you should start saving for a replacement bike. There is a A friend came back to find it gone after he met it in Chinatown. The policy of Kryptonite is tough. I understand legalities, but it's different when you can't stand by your product because it's 3 days beyond warranty registration deadlines which aren't even clear or broadcasted. There is a If you want a lock that does the job, I would suggest you look at the delivery guys in NYC. 100lb chains and quick reflexes.

👤After my lock broke down, the warranty department didn't respond to my emails for a couple of months, maybe they will see the negative review and finally respond.

👤The design of the keyhole cover is terrible. It's so flimsy that it arrived broken out of the box. There is no excuse for the design on this. The cover should be riveted to the metal and then sealed with a yellow covering. There is a They cheaped out so badly that two screws on the outside went through the yellow covering. They drilled two additional holes that expose the internal mechanism to water instead of just the keyhole. The problem is worse. The screws do not screw into the metal of the cylinder, but into a cheap piece of plastic. There is a This lock is more expensive than a child's toy, and they rig the plastic around the keyhole worse than a toy. This will let water in and cause the mechanism to rust. obsolescence is planned

👤I'm away from them and need to secure high dollar bicycle investments. I use different lock/chain/u-locks in order to maximize deterrence and slow down thieves the most. I realized that a determined thief will eventually defeat any security measure if given enough time. The Mini is in conjunction with a New York Disc Bike Lock. I use American Lock A700 and Master Lock 931 padlocks to secure my other bikes. The 25 year old bent-end Kryptonite long-shackle U-locks in my collection have been used to secure my extension ladders and utility boxes. The toughest U-lock in the world will be on my list of locks to acquire by the end of 2019. The Abus Granit Extreme is 59. Replacing the bikes will be worth it, even though it is pricey. A small investment may prevent a big expenditure in the future. Bike thieves, thanks for reading and for sharing your stories.

👤I've had a bike lock for a long time. I have never had my bike stolen while I ride around Brooklyn or Manhattan. A few years ago, I found the lock and steel completely unaffected, even though the rubber casing had been cut open. The thief was stopped. Thought it was expensive. It costs me about $8 each year for it, and it shows no sign of slowing down.

Up to $2, 500 Reimbursement for 1 Year included in the Anti-Theft Protection Offer.

Brand: Kryptonite

👤This lock was purchased last week. I used it on my bike for two days before it was stolen, and had no one to contact about the warranty. A few blocks away, a bike shop said that they don't carry U locks anymore because of how easy it is to break them. The manager said chain locks move when someone is trying to cut them with a saw. U-locks are easy to cut through as they are solid and don't move around. You should get a chain instead of the U lock, because Kryptonite makes good products.

👤I have not had a lock in a week and I have broken one of the keys. I dropped a key in the front disc brake, but the key was cut in half. I think I'll be requesting my two free ones soon. I have to fiddle with this thing for a while to get it open and to lock my bike. It's not clear which way to insert the key, so I end up flipping it over multiple times until I get the darn thing open. I don't want to take my front wheel off. I added a small cable for that, though I know it's not ideal. I'll sign up for the protection plan one day if I find my bike receipt. I would give my bike 3.5 stars if I could, because it's my main job. I'm on a ride that takes me one way to work. It's not heavy to carry in my backpack.

👤This is a great lock. I think it's a great lock because my $5k bike hasn't been stolen. It's hard to close and lock it. The U portion doesn't go completely into the locking mechanism, so it takes some fiddling and chutzpah until the key finally turns and locks the unit. I feel safe once it's locked because thieves will choose an easier target than my bike.

👤The Evolution 7 had a 4 foot cable. It wasn't a good fit for my hybrid when I tried to lock up the frame and tires. I couldn't lock my rear tire because the cable was long. The Messenger Mini was the reason I returned the Evolution 7. The Messenger Mini is perfect. The frame and tire of my bike can be locked up. I was able to secure my front tire with the 7 foot cable from Amazon. You want to buy a lock.

👤This will keep an honest person honest. It was an over purchase for me, but I kept it the same. I don't want to leave a bike unattended with a lock in a populated area since anyone can pick it up, regardless of strength or make.

👤My daughter took her bike to college and I wanted a big lock. Her bike is safe despite being stolen from dorms. It can be difficult to get locked up as it doesn't have much reach, but it works great.

👤It is worth the money. It is easy to carry while biking. I don't have to worry about my bike being stolen while I'm running my errand because I'm able to securely lock it.

Brand: Kryptonite

👤Don't buy this lock. I used it for the first time today after making sure it worked at home and after locking my bike up in Manhattan, the key wouldn't open the lock when I came back. The lock I bought doesn't work. The same thing happened with my previous lock. After a few years, I assumed that it was just aging. I'm pretty sure it was the lock. There were online discussions by people who described the same problem. They said it's not a problem to put grease in there. It's about the insides not lining up correctly. I can't go back until Wednesday to try and get my bike, it's stuck in Manhattan. It's supposed to rain between now and then. How can a major lock company sell locks that don't work? Thank you, Kryptonite.

👤After 6 months, I can say that the investment was worth it. I need to leave my bike locked up outside in the city, but it gives me peace of mind. No bike lock is absolutely theft-proof, but this one does a good job of discouraging bike thieves. There is a The keys/lock mechanism seems a little sensitive, so just make sure you insert the key all the way before turning, the only cons are that it is a bit heavy, and the keys/lock mechanism seems a little sensitive, so just make sure you insert the key all the way before There is a If you think of it as a workout regimen, you won't notice the weight in your bag unless you pack a lot of groceries or a laptop. The New York Standard U-lock is used with this. I recommend this to my biking friends.

👤This lock is serious. I tried to cut my lock with a bolt cutter. I used my strength and weight. I picked up a new one because they hardly made a difference. This is a tough lock.

👤The photos suggest that this is the evolution of the kryptolock series. It's a normal chain. It's fine for a cheaper bike. Trying to lock a wheel as well as the frame is a bit of a stretch.

👤This is close to being the perfect lock. The thick, square-cross-section links are more difficult to apply a cutting tool to than a U-lock staple. It's hard to put a tool into a short chain. It's difficult to get around the seat tube, rear wheel and bike rack, so you may have to just loop it through the frame. The lock body has a link that is inserted into it. I usually take the Millennium 2 U-lock to protect the bike against opportunists when I'm making a quick stop, but I also take the chain lock when I want really serious protection.

👤So far, so good. There were no attempts to steal the bike. Even a lock with a 6inch diameter of steal, grinder can cut into anything, so be careful when parking the bike in front of a busy shop or deli.

👤The lock is square and the chain is hardened steel. It's much harder to cut through this. Cheap metal and black fabric are used by other imitations to get away with it. The lock is easy to use and change, and the action is smooth and satisfying. You're going to want to just sit on your couch and lock it up for an hour. It was very satisfying.

👤Correcting my review was my initial opinion. There is a The lock broke after 4 months of use. I tried to get in touch with customer service, but they replied with a generic reply after a week.

👤This is a good choice if you want a chain lock. The integrated lock is made of metal and seems to be harder to cut through than plastic, and the chain is well built. The chain is heavy. The model strikes a good balance between security and weight. It isn't too heavy to carry, but standard bolt cutter would have a hard time with it. Heavy duty bolt cutter will be able to cut this. I wouldn't use this in a high crime area, I would use a sold secure or art rated U-lock. It's great as a secondary lock for things like locking wheels or bike storage.

👤This thing is very large. The first impression looks heavy. What I was looking for. I was afraid to leave my electric bike outside with just a regular chain. There is a I found this one for a reasonable price after doing research.

👤I'm feeling so sad about it. This is one of the strongest bike locks you can buy. When you watch the videos of someone cutting through a chain with a grinder in a few seconds, you wonder if you need something heavy and strong. If it takes 10 more seconds to cut through this, I don't think it will deter a professional, but it will be difficult for the guys with bolt cutter to get through so it has its advantages... It's hard to give a better rating because it's very heavy to carry.

👤Unless you only use the lock a couple of times a year, don't buy those $12 dollar chinese chain combination locks. The first chinese one we got lasted 2 months, we use it for our office about 6-9 times per day. They were nice enough to replace it for free, and that lasted for another 3 months. Finally decided to get this. Enough said, it's a heavy duty lock. It's still going strong if I don't write back.

👤I bought this lock after my son broke the key off in a mini lock and it was useless. The lock is easy to use and offers moderate protection for the low to medium theft risk scenarios I face. It is a step up from most combination cable locks as the chain links are very thick. I usually leave the lock at home because it's heavy. If you prefer a combo lock and don't want to leave a bike in NYC overnight, this might work for you.
