Another great thing about this lock is its woven steel cable. The part is designed for more protection but it also makes life a lot easier. Furthermore, the lock is pull- and drill-resistant and you can mount it by using a provided mounting bracket.

One of the things that might bother you with this product, though, is the locking feature. The part where the keys go in is plastic. It feels flimsy and might get easily damaged.

However, it might take some time to get used to the mechanism. The lock is sometimes difficult to position in the right way.

Here’s another high-quality bike lock from Kryptonite. It's a thick item made of quality steel that's able to resist a lot of abuse. Thanks to the hardened casing and a long looped cable, the item ensures ultimate security for your bike.

The lock offers excellent anti-theft protection and a long lifespan. The company incorporates new technology in producing crossbars that can resist cuts and twists, and this model has them, too. This means thieves won't be able to cut or dismantle the lock in any way. There's also a protective vinyl coating to make the product even more durable. Additionally, you'll get three stainless steel keys and a lifetime warranty.

However, you'll have to spend a little more to get this heavy-duty lock. If you're on a tight budget, the product might not be the ideal option for you. When it comes to the overall design of the lock, the biggest drawback is the fact that the key tends to get stuck. The lock is a little heavy and stiff, making it difficult to turn the key.

Still, you might have a few issues with setting up the lock at first. The package does include instructions, but they are vague and might cause even more confusion. Some customers also complained about the cable being too short for some bike models.

Benefits of Bike Locks

  • Store your lock on your bike. Most bicycle locks are designed to lock onto your bike when not in use, so you always have it when you need it.
  • They’re made of steel. The best bike lock is made from a strong steel material that cannot be cut or broken easily.
  • Different locking options. Most locks are available in either a key lock or a coded locking system, so you can choose the one that works best for you.
  • Variety of lock styles. With several options of locks, you are sure to find one that works for any situation.
  • Bolt cutters won’t work. Steel locks are strong enough to ensure that no one will be able to use bolt cutters on them.

Key Features

Key Lock

Most locks usually come with several keys. A key allows for an easy and quick way to install or remove the lock. Keys are convenient, and you can keep a spare key in your vehicle just in case you lose one.

Code Lock

Some of the best locks come with the ability to use a passcode. You enter the code by adjusting the numbers on the lock. Some locks can have four, five, or even 10 numbers. The longer the key lock code is, the more secure the lock will be. This makes it tougher to pick the lock. 

Other Considerations

  • Quality: Look for locks made from hardened steel. The thicker the lock, the tougher it will be to break by someone who is trying to steal your bike.
  • Chain Length: Look for a long chain that will offer you the security of keeping your bike secure through its main components. The more secure the chain wraps around and through the bike, the safer it will be.
  • Covered Chains: Thick chains covered in a protective material will add another layer of safety to your locked bike. There is less chance of someone taking your bike when it looks overly secured.


  • If you are using a combination code lock, make sure you use a code that isn’t easy to guess. Try to avoid birthdays or anniversaries, if possible.
  • For additional security, get a lock that is a vibrant color. They are more noticeable and can be spotted from a distance.
  • It’s best to write down or choose a combination code that you won’t easily forget. If you are unable to remember the code, you may be forced to cut off the lock or call a locksmith.


Q: Can a bike lock be used to lock multiple bikes?

A: Not all of them will be able to do this. To efficiently lock down multiple bikes, you need a lock with a longer cable. One that is just 4 feet long may not be enough to reach a second bike. 

Q: Where do I put a bike lock when I’m riding the bike?

A: Most locks can be stored in a bike bag or left on the bike while you ride. However, if you put it on the frame you want to make sure it is secured tightly and does not drag or hang from the bike where it can snag on a branch or on your clothing. More robust locks may need to be stored in a backpack or pannier.

Q: Will a bike lock scratch or dent the frame?

A: They can scratch and chip the paint on your bike if they do not have a protective pad around the chain. While many chains include PVC, rubber, or foam padding, others do not. If you need to replace the padding or want to protect your bike, you can wrap cloth around the frame or the chains.
