Kryptonite is the biggest name in the industry for a reason. Their products are built with toughness in mind. This particular model can withstand cutting attempts and won't break if twisted. It's 12.7mm thick to ensure thieves can't easily cut their way to your bicycle. It has a silver sold secure rating, which makes it a great choice for users in less densely populated areas or those who aren't riding fancy bicycle.
Kryptonite has their own security rating, too, and they rate this particular lock a 6/10. It'll keep most bicycles safe unless you're locking up for hours at a time in a high crime area.
U-models aren't the lightest types of locks out there, but it's fairly easy to slip this product into a bag and transport it. It's also fairly lightweight according to reviewers. It also comes with a way to mount it to your bicycle so you don't even need to make space in your bag for it.
This u-lock uses a double deadbolt to ensure your bicycle doesn't get snatched. You need to make sure to bring a key along but a key lock is tough for thieves to pick and get access to.

Sold Secure Rating
This product comes with a sold secure gold rating thanks to its 18mm thickness and smaller profile making it tough for thieves to break through.
Fairly heavy, so it's not the most portable option but it is smaller in profile than some other models making it easy to find room for it in a bag or backpack.

Sold Secure Rating
The Evolution Mini-5 has a sold secure silver rating and is 13mm thick. It's made of thick steel that's resistant to certain types of cutting tools.
It's more portable than other Kryptonite products with an overall weight of 1.94lb making it way easier to carry. It's smaller, which accounts for the lower weight.
It requires a key to open and the mechanism is placed to discouraged pickers. Like the New York model above, the Mini-5 also comes with three keys - one of which can function as a mini LED flashlight.
It comes with a special mounting bracket so that it can easily be transported. The angle is ultra-adjustable, too, and a special dust cover keeps out dust and debris so it doesn't get grimy over time.

Sold Secure Rating
It doesn't come with a sold secure rating but the company does offer a 30-day money back guarantee. It's is 12mm thick and made of zinc alloy. A u-shape is a good option for protecting your bicycle as long as the fit is tight enough to keep tools from getting in between.
It weighs about 1.8 lbs which makes it more portable than other options but users still commented on how heavy it was.
Using a combination mechanism is less secure than a key option but for users in low-crime areas or who need their bicycle secured for short periods of time, a combo means you don't have to worry about forgetting a key. For this model, a 4-digit code is required.
It is covered in a PVC coating which actually makes it thicker. This lining helps prevent your frame from getting scratched.

It's mini alright. The small model is easy to fit inside a pocket or bag compartment and weighs less than larger options.
It uses a key so you'll need one if you want to open it up. A double bolt mechanism ensures maximum security.
A soft coating on the exterior keeps your bicycle from getting damaged.
- No key required
- Weather resistant
- Easy to remember word combination

Sold Secure Rating
We couldn't track down a sold secure rating for this product and it's true that a combination model isn't as secure as a key one, but it's a good choice for the forgetful rider. Cable models are also less secure but they're easier to handle than inflexible u-models.
A cable option just isn't as heavy as a chain or u-model so it's a much lighter option that's easy to carry in a bag or backpack. It comes with a mounting mechanism as well.
The combination model requires a 4-letter word. It's easy to set and reset and there's no need to remember to bring a key.
The cable is 5-feet long so it's easy to double or even triple wrap it and make sure all the parts of your bicycle are secured. It also features a coating which prevents rust and protects your bicycle from scratches.
7. Master Lock Street Cuffs

Sold Secure Rating
It doesn't have a sold secure rating. It is, however, 12mm thick. It's quite resistant to cutting tools, as well.

It is coated in PVC so the steel cable won't scuff your bicycle.
9. Hiplok Lite Wearable
Unique, wearable design
Difficult to pick tumbler lock
Can be worn around the waist or one shoulder like a sling bag
Not for everyone
This is a very cool and unique option. Instead of attaching around your frame somewhere it's intended to be worn around your waist like a belt, or across one shoulder like a sling bag. This makes it great for people who are concerned with either scratching their bike frame, messing up it's clean and sleek lines or both. It also has reflective elements for safety which is a major bonus.Read more
It has a bronze Sold Secure rating so it's not the most secure option, but it definitely offers more security than a simple cable lock and the chain is hardened stainless steel. The fabric around the chain is tough nylon, and it has a tumbler locking system that is hard to pick.
If this one is for you, you probably knew it as soon as you saw it and realized what the design was for. It secures around your waist or shoulder so you don't have to worry about attaching it to your frame and potentially scratching it.
In addition to all of the things we mentioned above, it also has reflective features that help you to stay safe by being seen and standing out.
The hardened stainless steel chain and nylon chain cover were found to be long-lasting by reviewers and other gear sites on the web.
10. Sigtuna Gear 16mm U-lock
16mm steel u-bolt
Braided steel 1200mm cable
One-button release mounting bracket
Heavy and cumbersome at times
The Sigtuna is a super affordable yet heavy-duty choice for cyclists that are working with a more conservative budget. It is great for high-risk areas as well as being versatile with a cable and u-model combo.Read more
Sold Secure Rating
It doesn’t have a sold secure rating, but when compared side by side to the Kryptonite Kryptolok series (which has a silver sold secure rating) it definitely measures up. The cable is made from strong braided steel and covered with vinyl to make it harder to cut.
It is a bit heavy and can be a little more difficult to carry with you. However, the u-model itself can be used separately from the cable, which can also be used with other models.
The locking mechanism on this Sigtuna has double deadbolts that affix both sides to the crossbar and is made of 16mm of heavy duty steel, making it unlikely that potential thieves will be able to drill it. The keyhole has a cover and the lock comes with two Abloy keys.
This comes with a mounting bracket and the combination of the u-lock and the reinforced cable means you can choose the style in which you lock up your bicycle. The keyhole cover doesn’t just protect from theft, but from weather and dust too.
Criteria Used for Evaluation
Bike locks are all about protecting your bike. Here we look at the different styles of locks and their positives and negatives.
This is one of the most secure types of locks but it still has it's drawbacks. A large U-lock may allow potential thieves to use a crowbar or other similar device to gain leverage on the lock and break it. The great thing about these types of locks however is that they are generally very difficult to cut through with bolt cutters but they are easy and simple to use and usually have a key so you don't have to remember a combination. This gives them a good combination of security and ease of use. People who are highly concerned about the security of their bike will sometimes use a U-lock in combination with a chain lock in order to give themselves maximum protection. The downside is that U-locks can be heavy and cumbersome and require installing a special bracket on the frame of your bike.
As long as the chain is of a sufficient thickness this is one of the most secure options. That's because it will be too thick for a thief to cut through with bolt cutters so they will have to resort to using power tools such as a grinder or reciprocating saw. However, because of the moving nature of the chain it will be extremely difficult for them to cut through it without clamps and other additional tools, so unless the bike is locked up in a very remote location they're likely to be noticed before they're able to get too far along in their mission of thievery.
This is generally the least secure type of lock because it can be fairly easy to cut through with bolt cutters. They are very easy to transport with you however, all you have to do is wrap them around your handlebars, frame, or seat post. This type is really best for when your bike will only be locked up for a short amount of time such as when you're just going into a store for a couple of minutes. If that's all you need a bike lock for this is a great option as they're generally inexpensive and easy to use.
This can be a great option for people who want the portability and ease of use of a cable lock, but with security closer to that of a chain or U-lock. They usually come with a bracket for easy mounting to your bicycle frame, and are also easy to attach and secure.
Although we didn't include any of these on our list we want to let you know about them as they're a great option for locking your bike up at home. Most bicycle thefts actually occur at home, so this is a great way to prevent that. They take some work to install, but are a very secure and permanant solution. Most people will install them in concrete, although wall anchors are also available.
Your bike lock needs to be easy to carry round with you wherever you take your bike.
If you’re riding somewhere and securing your bicycle, you need to carry your lock with you so portability definitely comes into play. Smaller more compact ones are easy to store away, as are folding options, but the most secure ones tend to be fairly heavy. The tougher it is to get it open, the heavier it’s going to be. Some come with mounts so you can attach them right to your bicycle without needing to make space in your bag. Consider the bag you usually ride with and whether you have space to fit your new purchase.
What kinds of special features might you want to consider in your choice for a bike lock?
A lock should be covered or have a finish to ensure it doesn’t scratch up your bicycle. Some options also come with extra keys or a key replacement program in case you misplace or lose yours. You might not think this is going to happen to you, but once it does you'll be glad you have it! Expensive heavy duty ones come with warranty and guarantee programs. If your bicycle gets stolen there’s a process to go through to claim some of the cost. If this interests you, check out the company’s website to see what the rules and limitations are.
Consider when and where you ride your bike and where you will need to lock it up.
Where you ride your bicycle matters. If you’re securing your bicycle in an area with a lot of people, many other bicycles, and cameras, it’s unlikely that a thief will choose to steal your bicycle. That is unless you make it easy for them. Most thieves aren’t looking to spend a lot of time to steal a bicycle. The longer it takes, the higher the chance that they’ll get caught doing so. They’ll target the easiest mark right off the bat, so don’t make it your bicycle. High crime areas require the most secure protection while you can get away with less expensive options if you live in a non-metropolitan, safe neighborhood.
Expert Interviews & Opinions
Badly securing your bicycle can be just as bad as forgetting to lock it at all. There are countless cyclists out there who are still kicking themselves for only choosing to secure their front wheel. A thief can easily remove the wheel and make off with the rest of the bicycle. If you’re really concerned about thievery, wrap your lock around both your frame and wheel. You can even use more than one to really deter thieves. Avoid securing your bicycle in an area that’s dark and away from everyone else. Not only is it unsafe for your bicycle (a thief can work away at your lock without being interrupted), it’s not exactly safe for you either when you come back to your bicycle later. In a sea of other bicycles, choose a spot to secure your bicycle to that’s next to a nice expensive bicycle or, at least, one that’s nicer than yours. Thieves want either an easy target or an expensive one.
There are a few kinds of mechanisms. On this list, you’ll find that key models make up the majority. If you choose a key option, you need to be mindful to have your key on you at all times which some may find annoying but key models are a good choice because they’re quite tough to crack. Modern key models are almost impossible for pickers to get into and if they do, it’ll take them a while before they can pick the lock successfully. The list also features two types of combination models. One uses digits and the other requires the user to remember a 4-letter word. Most combination models require either 4 or 5-digits. They’re easier to figure out than a model that needs a key so, in terms of security, they’re a downgrade.
Other Factors to Consider
Sold Secure Rating
What exactly does this rating mean and where does it come from? Sold Secure is a non-profit from the UK that tests bicycle locks to help users choose a model that’s right for their needs. It’s not always easy to determine the difference in security from one product to another, so Sold Secure helps with that process. There are three security classifications: Gold, Silver, and Bronze. Of course, no brand is indestructible. However, the most secure options will take more time and effort to cut or break through. Gold rated ones are best for high crime areas since they are the strongest and most secure. Silver rated are usually less expensive and are better suited to lower crime areas or for bicycles that are less pricey, to begin with. Bronze level locks are meant to keep a bicycle secure for quick stop-ins to stores or for very low crime areas where the possibility of your bicycle getting stolen is low. On our list, you’ll find mostly Gold and Silver-rated models. Some on the list do not have a Sold Secure Rating. These tend to be very inexpensive and are appropriate for cheap bicycles or low crime areas. They were chosen because of high ratings from consumers.
Not every bicycle accessory should be chosen according to price but with bicycle locks, more expensive usually means more secure. If you’re not sure which option to choose, think about how much you paid for your bicycle. Are you willing to skimp on the cost and lose out on the money you paid for your bicycle if it gets stolen? If the answer is yes, then by all means, go for an inexpensive option. But if you paid good money for your bicycle and appreciate its value, go with the pricier model.
Frequently Asked Questions
Even the most intense bicycle model can’t keep your bicycle safe from determined criminals. If you have a particularly expensive road bicycle you may want to consider purchasing a second-hand bicycle for commuting so you don’t have to worry all day while your pricey ride is sitting vulnerable at the bus or train station.
It’s your call, but an unlocked bicycle to a bicycle thief is easy prey. It takes less than a minute to grab your unsecured bicycle. Honestly, better to secure it just in case.
More secure options are thicker and made of stronger materials. This doesn’t mean they’re indestructible but it does mean it takes way longer for a thief to break them. If you’re looking for cool new tech options, WiFi models may not be the way to go. They’re pricey and aren’t as secure as a u-model. There are other gadgets that might be more useful, however. Motion sensing alarms and GPS trackers might be helpful for keeping track of your bicycle, especially if you live somewhere more secluded. Also, consider the tech you already have and how that may increase the chances your bicycle will be stolen. Some fitness trackers are great for connecting with other cyclists and showing off mileage and routes, but they can also make you a target. Check your privacy settings and see if the apps you’re using have security options to keep your workplace and home address hidden.
It is definitely better to take preventative measures when it comes to bike theft. The likelihood that you’ll recover your bike is very small after it gets stolen, so make sure you do everything you can to prevent it before it happens. A bike lock is a good first line of defense. Invest in a quality product and try to make a habit of always securing your bike using the frame and the wheels. This will discourage people from dissembling the bike for easy access. In this same line of thinking, be aware of other custom components and how easy they are to remove or take. Consider anti-theft bolts.
When choosing a place to secure your bike, think about location. Easy to access areas that have heavy foot-traffic may prevent people from trying to steal your bike because of sheer visibility; on the other hand, a secluded area may mean your bike is less likely to get noticed. Weigh your options. Also, don’t assume that just because you’re somewhere familiar that your bike is safe. If your workplace has a garage or bike parking area be sure to still bring your lock, and if you park your bike in your garage lock it up. An open garage may prove an easy target.
Finally, be prepared for the day your bike may be stolen. Take pictures of your bike in advance and hang on to purchase receipts. Record the make, model, and the serial number of your bike. Some models have the option to register your bike, or you can check out free bike registry systems online. These may raise your chances of recovering your bike if it is found.
