Our Evaluation Criteria
We chose each of the bike locks on this list according to their sold secure rating, how easy they are to transport, the locking mechanism, and any extra features they offer the user. Below we delve into each of these criteria, explaining each one and why we think it defines the locks we chose. We hope that you can use these metrics to get a better understanding of what to look for in a quality bike lock, helping you to make a confident and competent buying choice in the future.
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 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 Sold Secure helps with that process. There are three security classifications: Gold, Silver, and Bronze. Of course, no bike lock is indestructible. However, the most secure locks 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 Sold 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 a while 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 or have a finish 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. A foldable lock is a newer kind of lock that is 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. 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: If you’re looking for cool new tech options, WiFi locks may not be the way to go. They’re pricey and aren’t as secure as a u-lock. There are other gadgets that might be more useful, however. Motion sensing alarms and GPS trackers might be helpful for keeping track of your bike, especially if you live somewhere more secluded. Also, consider the tech you already have and how that may increase the chances your bike 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.
Q. What else can I do to make sure my bike doesn’t get stolen?
A: 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 lock and try to make a habit of always locking up your bike using the frame and the wheels, if the lock allows. 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 lock up 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 locks 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.
