Master Lock 8143D Self Coiling Cable Lock

The Master Lock stands out most because it’s a very low price for a good quality lock. It’s able to keep your bike more secure than many other locks without breaking the bank.

The material of this lock is an important aspect as well because it is made with steel cable for durability. The steel is designed to resist against cuts that can typically counter this type of lock.

At 4 ft. long it’s simple to wrap this cable around any part of your bike and then just about anything you want to lock it to. It is a little short for larger trees, but can be attached to other poles or smaller structures.

How to Choose a Bike Lock

There are three different types of locks that you can choose from when locking up your bike. You can pick a U-lock, cable lock or chain lock to stay secure.

The right type of lock is mostly based on your personal preference, as all three types are high quality and make it more difficult for someone to steal your bike. If you are in a higher crime area, a chain lock is the most effective, while a cable lock is the least.

The Advantages of a Bike Lock

One of the biggest advantages to these locks is they make it difficult for someone to steal your bike. This is done best if the lock is sized to fit your bike and the object that you are locking it to.

These locks require additional tools if someone is still determined to take the bike. That means it will take more time and you or someone else might notice what is happening in time to stop them.

Things to Look For

The most important thing to look for is the size of the lock because a too large lock could actually give you the impression that it’s safe while still being easy to break. You want a lock that just fits around your bike and whatever you lock it to, without extra space to pry it.

Another thing to look at is the durability of the lock itself because you want it to stand up to pressure and prying at least somewhat. If someone tried to steal your bike by breaking the lock you want it to put up a decent amount of resistance.


Overall, the Kryptonite U-Lock is the better buy if you have a little bit more money to spend on it. This lock is made of sturdy material and will require more than wire cutters to get through.

This is going to work in higher crime areas as well as lower crime areas, whereas a cable lock is primarily for low crime areas. It also uses keys so there is no need to remember a combination, which can also improve your ability to get the bike back when you’re ready.

With this lock you also get to size it to your needs. It can be adjusted to work for different structures as well as extra items that need locking up.
