Best Bike Lock Buying Guide & FAQ

Your bike is probably one of your most precious possessions. You’d feel terrible if someone took it. That’s why you need a bike lock that plays an integral role in keeping it safe. Nowadays, most bike thieves are well-equipped with cutting tools. You don’t need a bike lock that you aren’t sure will protect your bike.

Most manufacturers know that bike thieves are becoming smarter. To be on par, they have upgraded their locks’ security systems to provide you with intricate locks that will give thieves a difficult time.

We have already provided you with information on the eight best bike locks that are on the market today. While a bike lock may not be something you want to spend much money on, you still need to have basic knowledge before you make up your mind.

Why Do You Need Bike Locks

Thieves strike when least expected, so you cannot take chances. It doesn’t matter even if you are in the safest city or town, or you’re just picking something from the shop.

While there may be many types of bike locks available, not all have the qualities to safely secure your bike. Thieves arm themselves with sharp cutting tools that can easily penetrate some bike locks. On the other hand, some have unique keys to open the lock using methods like passing, decoding techniques, and even picking. Before you choose any lock, you should keep these techniques in mind.

Benefits

  • Keeping your bike safe
  • Inexpensive (most of these bike locks are cheap, so you don’t have to break the bank to secure one)
  • Portable and easy to use

Types of Bike Locks

Bike locks are categorized into many types. In this review, we’ll only have a look at four that have the best Sold Secure rating. We’ll explain what this is in a moment. 

What also makes a bike lock stand out is its portability. Some locks are too heavy and cumbersome. For instance, you can’t bring ground anchor locks with you when going on a vacation. They are too heavy and are only best for locking your bike in your garage.

Choosing the best bike lock involves looking at the ease of use and the security it will provide to your bicycle. With all of this put together, we arrived at these four types of bike locks. 

Chain Locks

This is one of the most traditional forms of bike locks. But due to technology, it has been refurbished to offer a fresh level of creativity for better performance. They have an outer layer of plastic skin that protects the iron chain from rusting. The plastic covering also helps you to hold it firmly.

You can open it using a key or a combination code with numbers and letters. If a thief had to steal this, he must first memorize the combination code. You, therefore, have to be careful with who you tell the code.

It’s a very safe bike lock but not the best when you are in town. This is because a thief can easily cut it with a sharp tool. 

U-Locks

This horseshoe-shaped lock is one of the toughest bike locks you’ll ever come across. The numerous mechanisms make it bulky to avoid any chisel or hammer from breaking it. They are also oversized to reduce the amount of space a thief can insert a crowbar.

The locks come in different sizes so that you can choose your ideal size. The smallest and medium sizes can secure the frame and one wheel, giving the thief minimal space for operation. The larger U-locks, on the other hand, can lock both wheels while securely tightened around a fixed object.

Folded Locks

These locks are very durable and compact. That’s probably why they are the greatest competitor of U-locks if you put factors like weight and performance duration into context.

U-locks have a great mechanism for protection but they wear out faster than folded locks that have a tough outer material. This material does not easily give in to wear and tear.

Their main materials are metal plates placed inside a folding lock rotate. The lock can be folded around all kinds of objects. This also makes it easier to carry, as it’s also not too heavy.

Cable Locks

Cable locks resemble chain locks but are a bit longer. This increases versatility and also enables you to lock it on thick and strong objects. They are made with tough intertwined metal fibers that can resist a whole set of cutting tools for a limited time. The metals are covered with a layer of plastic to prevent weathering.

They are only good in low-crime areas, as professional thieves can easily break them. To make it more secure, you will have to top it off with a U-lock to secure some of the removable bike parts like the seat. But they are perfect if you just want to stop by the off-road shop to pick something up before you continue with your journey.

What to Look for When Buying a Bike Lock

The bottom line is that not all bike locks are created equally. As much as all of them have a similar purpose, each has a trait that gives it the upper hand over others when you keep factors like versatility and durability in mind. So what are these unique things that you have to check on to get the best bike lock on the market? Let’s have a look.

  • Sold Secure Rating

All the bike locks are divided into a three-tier security grading system. These include Sold Secure gold, silver, and bronze ratings. The quality of security decreases down the hierarchy respectively. 

Gold-rated bike locks top the list, as they are the most intricate bike locks offering the highest level of security. They can withstand up to five minutes from a full set of tools. Silver follows suit, but it doesn’t withstand a full set of tools. It’s not recommended for bikes over $1,000.

Bronze is the last category. It only offers protection against opportunistic thieves but not professionals. It’s suitable for cheaper bikes or low-risk use.

  • Thickness of the Lock

Thieves can and will do anything to steal your bike. They will bring as many tools as they can if they are determined to get away with your bike. You don’t want to lock your bike with a lock that’s not secure.

It’s important that you look for locks that have very thick bodies and shackles. In addition, they should be using steel alloys like boron to increase the durability. Thieves will need a lot of time trying to break the lock, which gives you time to take action. With this in mind, all your locks like padlocks, U-locks, and foldable locks should be thick and heavy.

  • Brand 

There are probably over a hundred brands of bike locks. All of them have a unique selling point, but not all walk the talk.

What we are talking about here includes the quality of the metals used and the methods of unlocking the locks. If the metal is of a lower quality, breaking it is easy. If the method of unlocking is not intricate, it gives more time to figure out your secret code.

Putting price into perspective here is not enough. After all, there is a high chance that you will run into low-quality locks from brands that do not even appear on the global market. So you have to take more time and think here before you make up your mind.

  • Location

How safe is your area? Is it crowded or isolated? These questions form a foundation for making a decision of the type of lock you purchase. In public areas, it’s not easy for a thief to steal your bike because they can be easily spotted and apprehended. Therefore, you don’t need an expensive and intricate bike lock.

On the other hand, an isolated area is a bit tricky when leaving your bike. You need a heavy lock. Plus, some areas are known for bike theft even though they are crowded. The thieves here are professionals and will know how to maneuver around without being noticed.

Tips for Buying and Using Bike Locks

It would help if you start by looking for a lock whose cost is within your budget. Some are too expensive, but of high quality. But this doesn’t mean that cheap locks are of low quality. In short, your ideal lock should be affordable and serve you better.

Plus, choose your transport style, and then your security level because it is more probable that you’ll like (and thus use) your new lock. The first aspect of style to think about is where you will ride your bike or where you’d want to carry your new lock. Here are more tips to use your bike lock effectively.

  • Lock your bike in a busy public place that is well-lit.
  • Make it hard for thieves to access it by placing it amongst other bikes or in a place where it is awkward to operate cutting tools.
  • Avoid leaving your bike unattended overnight.

Best Bike Lock FAQ:

We know that making a decision for any purchase is an uphill battle. You probably still have some doubts that you need to get cleared, especially if you have gone through an ordeal of losing your bike. Here are a few FAQs that will help you make the best choice in your purchase.

Q. Can you reset a bike lock?

A: Yes, you can reset a bike lock. If your lock came with a reset tool, insert the reset tool into the corresponding holes and push until you hear a clicking noise. Rotate the dials to the new four-digit combination of your choice. Use numbers that are easy for you to remember. Remove the reset tool, or flip the reset lever to its original position.

Q. When is it better to use a U-lock than a cable lock?.

A: While cable locks are convenient and easy to use, they are not as secure as U-locks. Therefore, they should be used as a secondary security device in high crime areas or to lock up quick-release components and accessories when securing your bike. A U-lock or high-security chain will always provide a more secure protection.
