10 Best Bike Locks
1. Kryptonite KryptoLok Series 2
Kryptonite is the biggest name in bike locks for a reason. Their locks 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 bike. It has a silver solid secure rating, which makes it a great choice for users in less densely populated areas or those who aren't riding fancy bikes.
Kryptonite has their own security rating, too, and they rate this particular lock a 6/10. It'll keep most bikes safe unless you're locking up for hours at a time in a high crime area.
U-locks aren't the lightest types of locks out there, but it's fairly easy to slip this lock 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 bike so you don't even need to make space in your bag for it.
This u-lock uses a double deadbolt to ensure your bike 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.
The bike lock is backed by an impressive Lifetime Warranty and comes with a protection service offer from the brand. It's also sold with an extra cable that's 4 feet in length so you can secure other parts of your bike.
- Lightweight for a u-lock

2. Kryptonite New York Fahgettaboudit
This u-lock comes with a solid secure gold rating thanks to its 18mm thickness and smaller profile making it tough for thieves to break through.

It's covered with vinyl so that the lock doesn't scratch your bike. The u-lock is also sold with three keys so you won't have to worry about losing them or forgetting one. Just put one in each of the bags you own! One of the keys comes with an LED light.

Our Evaluation Criteria
Here’s an explanation of each of our evaluation criteria in detail. We chose the bike locks on this list according to their solid secure rating, how easy they are to transport, the locking mechanism, and any extra features they offer the user.
Solid Secure Rating
What exactly does this rating mean and where does it come from? Solid Secure is a non-profit from the UK that tests bike locks to help users choose a lock that’s right for their needs. It’s not always easy to determine the difference in security from one bike lock to another, so Solid Secure helps with that process. There are three security classifications: Gold, Silver, and Bronze. It should be noted that all bike locks can be defeated in time. The most secure, though, will take more time and effort to cut or break through. Gold rated locks are best for high crime areas since they are the strongest and most secure. Silver rated locks are usually less expensive and are better suited to lower crime areas or for bikes that are less pricey, to begin with. Bronze level locks are meant to keep a bike secure for quick stop-ins to stores or for very low crime areas where the possibility of your bike getting stolen is low. On our list, you’ll find mostly Gold and Silver-rated locks. Some locks on the list do not have a Solid Secure Rating. These locks tend to be very inexpensive and are appropriate for cheap bikes or low crime areas. They were chosen because of high ratings from consumers.
If you’re riding somewhere and locking up your bike, you need to carry your lock with you so portability definitely comes into play. Smaller more compact locks are easy to store away, as are folding locks, but most secure bike locks tend to be fairly heavy. The tougher it is to get that bike lock open, the heavier it’s going to be. Some bike locks come with mounts so you can attach them right to your bike without needing to make space in your bag . Consider the bag you usually bike with and whether you have space to fit your new bike lock.
There are a few kinds of locking mechanisms. On this list, you’ll find that key locks make up the majority of the bike locks. If you choose a key lock, you need to be mindful to have your key on you at all times which some may find annoying but key locks are a good choice because they’re quite tough to crack. Modern key bike locks are almost impossible for lock pickers to get into and if they do, it’ll take them awhile before they can pick the lock successfully. The list also features two types of combination locks. One uses digits and the other requires the user to remember a 4-letter word. Most combination locks require either 4 or 5-digits. They’re easier to figure out than a lock that needs a key so, in terms of security, they’re a downgrade.
What kinds of extra features might you want to consider when it comes to a bike lock? A lock should be covered in something to ensure it doesn’t scratch up your bike. Some locks also come with extra keys or a key replacement program in case you misplace or lose yours. Expensive heavy duty locks come with warranty and guarantee programs. If your bike gets stolen there’s a process to go through to claim some of the cost. If this interests you, check out the bike lock company’s website to see what the rules and limitations are.
Here are a few other things to know and keep in mind when choosing a new lock for your bike.
Type of Lock
There are a few main types of bike locks that you’ll find on this list and for sale. A u-lock is one of the most popular, and for good reason, they’re usually made of super-strong materials that are way tougher to get through even with high-quality tools used by thieves. The shape makes it easy to secure a bike so that little room is left which means thieves can’t easily get leverage to break the lock. They are, however, more expensive than other kinds of locks. But if you want the most protection, they’re your best bet. Most u-lock require keys to open. Chain locks and cable locks are easier to use since they aren’t rigidly formed like a u-lock. This makes it easier to quickly lock up a bike to virtually anything. Cable locks are lighter while chain locks can get pretty cumbersome to carry. Both are secure options but it’s not super tough to break through especially for the determined thief. Foldable locks are a newer kind of lock that are great for storing and transporting. Like cable and chain locks, they’re less secure.
Where you ride and lock up your bike matters. If you’re locking up your bike in an area with a lot of people, many other bikes, and cameras, it’s unlikely that a thief will choose to steal your bike. That is unless you make it easy for them. Most bike thieves aren’t looking to spend a lot of time to steal a bike. 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 bike. High crime areas require the most secure bike locks while you can get away with a less expensive lock if you live in a non-metropolitan, safe neighborhood.
Properly Locking Up Your Bike
Badly locking up your bike 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 and lock up their front wheel. A thief can easily remove the wheel and make off with the rest of the bike. If you’re really concerned about bike thievery, wrap your lock around both your frame and wheel. You can even use more than one lock to really deter thieves. Avoid locking up your bike in an area that’s dark and away from everyone else. Not only is it unsafe for your bike (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 bike later. In a sea of other bikes, choose a spot to lock up that’s next to a nice expensive bike or, at least, one that’s nicer than yours. Thieves want either an easy target or an expensive one.
Not every bike accessory should be chosen according to price but with bike locks, more expensive usually means more secure. If you’re not sure which option to choose, think about how much you paid for your bike. Are you willing to skimp on the cost of a bike lock and lose out on the money you paid for your bike 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 bike and appreciate its value, go with the pricier lock.
Q. I have a really expensive road bike. How can I keep it safe from thieves?
A. Even the most intense bike lock can’t keep your bike safe from determined criminals. If you have a particularly expensive road bike you may want to consider purchasing a second-hand bike for commuting so you don’t have to worry all day while your pricey ride is sitting vulnerable at the bus or train station.
Q. Is it worth paying more for a lock than I paid for my bike?
A. Probably not. Thieves will target more expensive bikes or bikes that are poorly locked up or not locked up at all. Unless you live in a bad neighborhood where bikes are commonly stolen, you can get away with a less expensive bike lock.
Q. Can’t I just use a cable lock? It’s easier to use!
A. If you think your bike will be safe with just a cable lock, go for it. But while cable locks are easier to use, they’re definitely not as sturdy as a u-lock.
Q. Do I really need a bike lock? I don’t live in a big city and don’t leave my bike unattended very long.
A. It’s your call, but an unlocked bike to a bike thief is easy prey. It takes less than a minute to grab your unsecured bike. Honestly, better to secure it just in case.
Q. If all bikes locks can be broken into, what makes one more secure than another?
A. More secure locks 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.
Q. What about those new fancy WiFi enabled locks?
A. They’re pricey and aren’t as secure as a u-lock.
