The end of winter means one thing for cyclists: it’s time to stock up on the essentials. Having a proper helmet is number one, but after that, having the right bike lock comes a close second. There’s no one-size-fits-all lock, what’s “right” varies from person to person. Protecting your bike from theft is important when you’re  commuting through the city or touring through mountain trails. Your lifestyle determines which lock is best for you and your bike. No matter where or how you ride, this guide will help you find the right lock for you.

How To Choose the Best Bike Lock

It’s important to decide what your needs are before you determine your perfect bike lock. What are you using your bike for? If you’re commuting to work in an urban environment, you will need a different lock than someone who is going for a leisurely evening ride. Is bike theft common in your hometown? Then maybe you’re better off with a heavy-duty chain. 

Think through different scenarios you’ll likely be in. Locking up outside the local convenience store to run in and buy milk is different than leaving your bike outside of a large office building for hours. Whatever your environment is, decide what safety features you need to feel comfortable leaving your bike by itself.

Next, think about where you (and your bike) live or spend the most time. What’s the weather like? Would you be better off with something water-resistant that can hold up to the elements? If you’re in sunny San Diego, you likely won’t need to worry about this. If you’re in Canada, you absolutely will. It’s a good idea to consider all these factors before purchasing your lock.

Lock Types


U-locks are named after the steel “U” that locks into the bar. They’re the complete package, offering quality theft protection while still being portable and lightweight. Usually, U-locks need a key to open. The security of these locks vary. Different grades of steel, thickness, and how it is secured will determine how much protection each model offers. But, if you’re looking for a bike lock that can be used in most scenarios, the U-lock is the best choice.

Chain Lock

Chain locks are usually the toughest options. In places where theft is common, a chain lock combo with a U-lock is the best way to keep your bike safe. Many chain locks can’t be cut through or broken unless the person stealing it has specialized tools and equipment. 

Cable Locks

It’s hard to beat cable locks for flexibility and weight. They’re great for parking your bike in places where a U-lock won’t fit, like a tree or a building column. Cable locks also work well if you need to anchor multiple bikes at a time. 

Folding Locks

If you’re on your bike for long periods of time, touring or otherwise, it doesn’t get much better than a folding lock. These are newer to the market but are already cultivating a loyal following in cycling communities, and for good reason. Folding locks are compact, efficient, and don’t sacrifice when it comes to protection.

Security Rating

If you’re unsure of what the specifications mean on any bike lock description, the Sold Secure rating system can be a great guide. Sold Secure is a non-profit that aims to reduce crime by rating security products, like bike locks. The ratings are simple: Bronze is the lowest rank and has the lowest security rating, Silver is the next step up, and Gold is the most secure.

Keys vs Combination

Choosing a keyed lock versus a combination lock boils down to what you’re more likely to remember. Keyed locks are most often used on U-locks and chain locks. The biggest drawback to using a keyed lock is the key itself, which is tiny and can be easily lost or forgotten. With a combination lock, you don’t have to worry about misplacing or forgetting a key. However, you do have to remember the code you choose. Cable locks are more likely to use combinations to lock up over keys.

FAQs for Bike Locks

What are Bike Locks Made Of?

Most bike locks are made from a combination of steel and plastic or vinyl coating. The thicker and higher grade the steel, the more difficult it is to cut through. Hardened steel—popular with U-locks—is a specially treated kind of steel that cannot be broken with standard lock cutters. Cable locks, on the other hand, are made of a thinner wire that is then covered in a protective outer layer.

Are U Locks better than Cable Locks?

This depends on your needs. Cable locks can be easily packed away and transported. However, they are also easier to cut through. U-locks, tend to be stronger and more durable but lack the flexibility of a cable. There are combo cable and U-lock sets available if you don’t want to choose between the two.

Can U-locks be cut?

Yes, U-locks can be cut. By what tool and how easily depends on the type of steel used in the lock. Locks with lower-grade steel will be easier to cut through than hardened steel. Most U-locks can’t be cut with a simple lock cutter–though some can–but if your thief has a hacksaw or a power tool, they may be able to cut through even a stronger lock if given enough time.

What Bike Lock Should I Buy?

This all goes back to the basics. Do you commute to work in a high-crime urban area? A chain or heavier duty U-lock might be best for you. On the other hand, if you’re riding on your local suburban bike path after work, you might not need as much protection. Think through what you hope to get out of your lock, choose the lock that best fits your lifestyle and setting, and then hit the road.
