Best Bike Locks In Summary

What types of bike locks are available?

Different types of bike locks are available in the market. Choosing the correct type of bike lock for your bike is necessary since it determines a number of things:

  • How simple it is to use?
  • How well does it stand up against a crook?
  • How much does it cost?
  • How much does it weigh?

Together with giving a bike thief the toughest time he could have imagined, a bike lock should be simple to use for the cyclist. Most of us will end up leaving the bike parked without it, if the bike lock takes more than a minute to secure. And that sort of negligence is exactly what the bike thief will be waiting for. Choosing the correct level of security together with ease of use for a bike lock that is lightweight and affordable is very important.

Here are a few of the most common types of bike locks that you will come across.


U-LocksA U-lock, sometimes also called a D-lock, is very similar to a padlock. These varieties are generally cheaper as compared to chain locks but will offer a superior level of security that will require power tools to break. Since most bike thieves will carry only hand tools, there is no way that they can defeat these bicycle locks. These bike locks are usually used with long chains to fasten around the bike.

As for the price, the U-locks will generally lie within the range of $40 to $120 for the most expensive bike locks. The more expensive models will generally offer a higher level of security for your bike. These higher end U-locks will come with double deadbolts which would require the thief to make two cuts, using power tools, to break the lock, which makes it practically invincible for most bike thieves.

Chain Locks

Chain LocksIf you are considering a chain lock, you need to find one that has a chain and shackle made of strong material such as hardened steel. Only then will it give the same level of security as that of a U-lock. The chain should offer a length that can hold the bike frame and wheels together and lock it with a tree or other such solid object on the ground. The cheapest chain locks can cost you as low as $40 while the most expensive ones can be as high as $400. You need to find the right balance between price, level of security offered by the chain lock and its weight depending on your circumstances.

Folding locks

Folding locksFolding locks are a popular choice of daily commuters for the convenience that they offer over chain locks and cable locks. Their main selling point is their foldable structure which takes up a compact shape when folded up, making it easier to transport. However, since the cheaper models of folding locks will be easily compromised with a bolt cutter that the thieves usually work with, you need to be especially careful when making your selection. On the plus side, they allow you to lock the bike to a tree or a post just like a chain lock since the foldable structures can be wound around larger objects.

Cable Locks

Cable LocksCable locks are strands of steel wires that are held together inside a plastic rod. These are the types of bicycle locks that you need to avoid since their security can be compromised very easily using a bolt cutter. However, the reasons why they are still popular among many cyclists are their attractive prices and convenience. The entire point of a bike lock is to offer uncompromised security. Once you are guaranteed that, you can go ahead and think about the secondary factors such as price or convenience. This is why cable locks aren’t worth your time since they do not deliver the primary purpose of a bike lock. They may, however, be a suitable pick for cyclists who usually park their bikes in low-crime areas and do not leave it unattended for long.

Bike Lock Buyer’s Guide:

Have you picked the correct type of bike lock which suits you, your budget and your bike best? You have made a major decision into buying the best bike lock but that’s not all. There are a few other things too which you need to think over before you can finally make your purchase.


Think in terms of how you’ll be carrying your bike lock when you are out for a ride on your bike. Will you carry it around all day inside your backpack or in your pant pockets; you’ll be needing a lightweight bike lock if you do so. However, if you leave the bike lock secured to a tree or a post on the spot where you park your bike everyday when you head out for work or school, weight is not much of an issue since you won’t be carrying it around much. Usually the heaviest of the chain locks and folding are also the securest, but you do need to make sure that these locks do not weigh you down while carrying them.


You also need to consider the size of the lock to make sure it is simple to transport. U-locks like the Kryptonite Messenger Mini are the most compact and lightweight models that you will find, making them easier to carry around especially for daily commuters. Also popular for their compactness and ease of transportation are the foldable locks which will fold out to make a sturdy, powerful chain and fold up to take a compact shape which you may carry easily inside your backpack.


Most popular choice of material that you will come across when looking for bike locks is hardened steel. Some higher end bike locks also use more expensive materials such as Titanium. Whether you use bicycle locks made with hardened steel or those made with Titanium, you can rest assured that they will not be affected with the ordinary tools that the crooks usually carry. The only way to break such locks is to use angle grinders which require time and create a lot of noise, both of which a thief cannot afford without giving himself away. Avoid purchasing bike locks made out of cheaper alloys since they can be easily compromised with hand tools.

Dual Security

If you live in an area where there is a high crime rate, you may want to invest in two locks rather than one. Most city dwellers follow this practice to raise the security level for their bike and give the thieves a tougher time. If you do want to invest in two locks, the best option is to purchase a D-lock to secure around the bike frame and another chain lock or cable lock that secures the D-lock to the wheels of the bike.

Smartphone Tethering

Some advanced bike locks make use of Bluetooth technology to synch with an app on your Smartphone to unlock your bike without a key. These varieties of bike locks are a preferred choice for cyclists who tend to lose keys. Using smart bike locks such as these will eliminate the need to keep track of the keys.

Built-in Alarm:

Another one of the advanced features that some high end bike locks will include besides Smartphone tethering is an alarm system. These alarms are an excellent bonus you can get with a lock since they will sound and alert the owner of the bike if the bike security is being compromised.

How do I lock my Bike?

Just as important as choosing the correct bike lock is to know how to use it properly. Many cyclists who use strong, expensive locks with their bike do not understand the correct procedure to lock their bike with it. The result is that they are not using the bike lock to its truest potential which may result in the bike being stolen despite the impressive features of the bike lock. Here is how you you lock your bike correctly.

First take your bike close to a post or a tree which you are going to secure it to. Next, run the chain through the frame, then the rear wheel, then the front wheel and then through the post before locking it. To lock all these four components with a single bike lock, you need one with a longer chain. If your bike lock does not include a longer chain, you may also consider using two bike locks; one that will secure the frame, rear wheel and the post and another one that will lock the front wheel with the frame of the bike.

If you own a foldable bike, a bike lock with a smaller chain will do the job since you will only need to take it through the frame and then through both the wheels, which are aligned with each other in the folded form of the bike, before passing it through the post.

Additional Tips that will Guarantee your Bike’s Security

Besides purchasing a good bike lock and using it correctly, there are certain additional tips as well which you can follow to guarantee your bike’s safety.

  • Look for busy, well-lit places to park and lock your bike rather than quite, dark places where a thief can easily use tools like angle grinder without being noticed.
  • The lock should be hanging taut in air rather than being pressed against the ground. If the lock is sitting on the ground, it will be easier for a thief to break it open.
  • A slack chain of the bike lock also needs to be avoided. Such a chain will make it easier to fiddle around and set it to a position that will make it easier to cut. You need the smallest chain that will tie all the essential components together without leaving any slack. A taut chain will be much more tedious for a thief to work with.
  • Make sure that the structure you tie the bike to, is solid and stands tall on the ground. Smaller trees can easily be chopped off by someone who plans on taking the bike. Also avoid short sign posts since the bike and the lock can easily be lifted over the head of the post to set them free.
  • Keep hold of the serial number of your bike. Store it somewhere safely, in your Smartphone or a diary so that you may hand it over to the police for tracking it down in case your bike does get stolen, even after all the necessary security steps. However, rest assured that it will most probably never come down to this, provided you take all the necessary security measures and use a good bicycle lock.


Without a doubt, you have spent good money into purchasing your bike and you love it. Not only did you spend money, you might also have put in time and effort into finding a bike that suits you right and that you love riding. Are you willing to give all that up at the hands of a thief simply because he was smarter than you? If the answer is no, what you need right away is the perfect bike lock using which you can leave your bike out in the streets with complete surety that it will be there when you return. A small investment in a bike lock today can save you from the loss of a bigger one in the future.
