Common Types of Bike Locks

Depending on the locking mechanism that they use, bike locks are divided into several categories. Sometimes, bike locks are a mix of several different locking mechanisms, as to provide the user with extra means of keeping their bike safe. For example, a U-lock can be combined with a regular key lock or even a combination lock, for added safety. There 5 main types of bicycle locks.

U-Locks


These are probably the most common types of bicycle locks that the people around you use. They have a very solid locking mechanism, which can withstand pressure and force caused by tools such as chisels or hammers. Their name comes from the fact that they are shaped much like a horse shoe. The reason why they are shaped like that is to allow you to lock them leaving as less leverage space as possible. This will prevent forced breaking, caused by crowbars – one of the most common tools used in the theft of bicycles. That’s why it’s important to pay close attention to the size of the U-lock you purchase. In general, people choose small or medium models when they want to lock a single wheel plus the frame to a fixed object. Buyers of larger locks want to attach both wheels plus the frame to a fixed object. Whatever the case is, you need to make that the remaining space after the bike has been secured is as less as possible, so that no prying objects can fit through there.

Cable Locks


These are also practical, but they are not as breakthrough-resistant as U-locks. With a wire cutter, a thief can easily cut through the cable and steal the bike, so they aren’t really recommended if you live in an area where bike theft is a major concern. Most cable locks include a combination or a key lock, but some models don’t, and you’ll have to purchase the padlock separately. Other models come with armored coating. If the cable is replaced with a heavy-duty chain, it will be more resistant to the average pair of wire cutters and will do a better job at keeping your bike safe.

Keyed Locks


Keyed locks can be opened with cylindrical or flat keys. In the past, you could open a cylindrical key lock by simply using a ballpoint pen and they’ve gained a bad reputation because of that. However, newer models have fixed this issue and are more reliable.

Combination Locks


These types are preferred to key locks, as they don’t require the additional care of a key. By simply remembering a 4-digit code (as you’ll later see in this article, there are some exceptions – we’ve found combination pads that support a 5-digit code), you can unlock your bike without having to worry that you’ll lose the key. Combination locks are commonly found on cable locking mechanisms.

Locking Wheel/Seat Skewers


These are ideal for areas with a high number of registered crimes, as they make it very hard on thieves to steal bikes. Many models come with a special wrench for installing the mechanism.

Top 6 Best Bicycle Locks Reviews

Kryptonite New York Fahgettaboudit 1415 Bicycle Lock

  • Dimensions: 3.1 x 1.2 x 1.2 inches
  • Weight: 15.25 pounds
  • Lock type: Key Lock

The 14 mm six-sided chain links on the Kryptonite basically had us convinced at first glance. The chains are made of hardened manganese steel, which is pretty much indestructible (we highly doubt that thieves would try to steal your bike with a blowtorch anyway). The nylon cover swallows the chains to give it a more elegant look. At both ends of the chain, you can find a disc lock that features a high performance 15 mm steel shackle, adding even more metal to this already durable combination.

The locking mechanism is enhanced by a double deadbolt and a disc style cylinder which is drill and pull resistant. By all these powers combined, it seems like this Kryptonite bike lock is impenetrable. A convenient dust cover will protect the key hole, making sure nothing no debris will ever block it. This bicycle lock comes with 3 stainless steel keys, one of which comes with a high intensity bulb, so you can easily find it. Don’t get us wrong, the Kryptonite can still be broken through, but it takes a lot more time, patience, force and better tools, so there’s a high chance that thieves will leave your bike alone and focus on another, more unprotected one.

Pros

  • Due to its size and weight, it can be very intimidating for thieves.
  • Lifetime warranty.
  • You can register for a year of coverage for your bike.

Cons

  • Extremely heavy compared to other types of bike locks.
  • Not indestructible (a.k.a. if someone wants to steal your bike, has great tools, a lot of time and helluva patience, they will).

Via Velo Bike U-Lock

  • Dimensions: 2.2 x 8.1 x 10.2 inches
  • Weight: 3.04 pounds
  • Lock type: U-lock

Next in line, we have the Via Velo U-lock. This locking mechanism was designed to make it tough on thieves that have set their eyes on your bike. The lock cylinder is both pull and drill resistant, while the double bolt crossbar locking mechanism will make sure no one tries to pry your bike away. The lock is pick-resistant and the combination between the rubber casing and the steel shackle is there to make sure no one can cut through this lock.

The steel cable measures 70 inches in length and is covered by PVC coating. The mounting bracket makes it easier on the user to store the lock when needed, making sure it won’t get in the way. The lock is conveniently covered in order to avoid dust and debris from clogging up. The Via Velo mounting bracket is compatible with most bike models available on the market (frame measurements should be between 0.79 to 1.65 inches) and it features an anti-slip pad that secures the bracket in place. The lock is shipped with 2 keys, which is always convenient in case one of them is misplaced.

Pros

  • Convenient mounting bracket that keeps the cable from getting in your way as you cycle.
  • Corrosion resistant.
  • Lock cover protects the keyhole from dust and debris.

Cons

  • Not long enough to lock both wheels.
  • May be too small for a large men mountain bike.

Titanker Cable Lock

  • Dimensions: 5.1 x 5.1 x 2 inches
  • Weight: 11.2 ounces
  • Lock type: Cable Lock with Combination Pad

Hands down, this is one of the most light-weight bike locks you’ll ever come across. With only 11 ounces in weight, it kind of makes you wonder if this does a good job at protecting your bike from potential prowlers. The Titanker cable lock comes with a combination locking mechanism that requires a 4 digit code to open. As advertised, it can lock several others means of transportation, from skateboards to ATVs.

The steel cables are protected by a PVC coating, in order to prevent scratches and enhance the overall durability and lifespan of the product. While it’s true that the 4 digit combination lock allows a high number of possibilities and figuring out the code won’t be easy, bike thieves don’t exactly rely on their code cracking abilities and use solid tools to try and steal your ride. This bike lock also comes with a mounting bracket, which is easily attached to your frame or seat post. Overall, this is a good lock for areas with low bike theft crimes. We dare to say that it’s more intimidating than anything else, so if you’re looking for something that’s actually going to make it hard on thieves, you may want to focus on another bike lock model.

Pros

  • Tactile dials make it easy to transition from one digit to another.
  • Included bracket makes it easy to store the lock away when it’s not needed.
  • Low cost option for those who don’t need to spend a lot of money on bike locks.

Cons

  • A number of buyers have reported that it’s fairly easy to cut through the cable and steal the bike.

Amazer U-Lock

  • Dimensions: 10.3 x 7.9 x 1.3 inches
  • Weight: 1.8 pounds
  • Lock type: U-lock with Combination Pad

We love it when we come across bike locks that use plenty of steel. That makes them harder to scratch, break, pry or saw through. This Amazer U-lock comes with a 12 mm steel shackle which is covered in a 3.85 mm layer of PVC coating. So, not only is it harder to break compared to locks not made of steel, but the PVC coating will prevent your bike from getting scratched. The combination pad eliminated the need for carrying around a key which, as you know, is one more thing to worry about. You can setup a 4 digit combination and change it periodically, just for some extra peace of mind.

The combination pad comes with a dust cover which is super awesome because, in time, the rotating number disks can be worn out and difficult to rotate, as dust accumulates between them. The cylinder itself is made from steel and solid zinc alloy. While the lock is pretty sturdy, cutting through it is not impossible. It takes a solid pair of bolt cutters and some natural human force to succeed, so it may be wiser to buy it if you live in low crime areas.

Pros

  • Combination lock relieves you from the stress of looking after the key.
  • Dust cover to protect the combination pad.
  • Convenient PVC coating, to avoid your bike from getting scratched.

Cons

  • Brute force and a solid pair of bolt cutters can break the U-lock.
  • Issues have been reported with the combination resetting randomly.

Sportneer Bicycle Chain Lock

  • Dimensions: 39.4 x 0.3 x 0.4 inches
  • Weight: 1.57 pounds
  • Lock type: Chain Lock with Combination Pad

The Sportneer chain lock is taking combination pads to the next level by including one extra digit to the mix. That means that you have a 5 digit combination code required to open this lock. The cable itself is made from manganese steel that measures 0.27 inches in thickness. The zinc-plated coating promises to shield your bike frame from any scratches. The length of the cable is 3.2 feet and serves for locking multiple items, even gates, fences or tool boxes. The chain is protected by a cloth sleeve, to ensure a longer lifespan.

Since this a low priced unit, chances are you don’t really get the protection you’re looking for. If you live in an area with a high number of registered bike thefts, the Sportneer lock won’t prevent determined thieves from doing their job. The chain is long enough for you to attach one of the wheels to a bike pole, but won’t do the trick if you want to secure both wheels.

Pros

  • 5-digit combination code compared to similar models that only allow 4 digit combinations.
  • Easy to install and setup the combination.

Cons

  • Low end product, not the finest choice for ultimate protection.
  • Combination pad feels cheap, prone to breaking pretty quick.

Kryptonite KryptoLok Series 2 U-Lock

  • Dimensions: 9 x 4 x 1.2 inches
  • Weight: 3.59 pounds
  • Lock type: U-lock with Key

Pros

  • You get 2 extra keys free of charge if you lose the original ones (you have to register on their website to benefit from this).
  • Possibility to lock 2 bikes simultaneously.

Cons

  • Key tends to jam into the locking mechanism.

Conclusion

This time, there’s probably no surprise on which our favorite bike lock is. Compared to every other model we’ve look over so far, the Kryptonite Fahgettaboudit stands out in pretty much every possible aspect. The name is pretty cool too! But the name won’t scare thieves away. However, the lock in itself will. Everything on this product basically screams stainless steel. The six-sided chains on the product look sturdy enough to be used as climbing gear, as they offer a sense of everlasting durability. Since the chain in itself would probably scratch about any bike frame, Kriptonite has conveniently covered it with a protective nylon cover, as to make sure that doesn’t happen.

The cylinder looks all cute when you first see it, but once you hold it, it pretty much feels like you’re holding a grenade. It comes with a double deadbolt locking mechanism that will make sure everything is help into place. You get 3 keys when you purchase this product, one of which features a high intensity light bulb that makes it easier to find the keyhole and unlock the mechanism even in low night conditions or after dark. The sliding dust cover is also a cool feature that’s worth mentioning, as it keeps the cylinder protected.
