Best Bicycle Chain Lock

Read on as we explore the best bike chain locks on the market. If you were looking for honest and unbiased reviews, this is the place to be.

1. Kryptonite New York FAHGETTABOUDIT Chain

If bike chain lock reviews are anything to go by, the Kryptonite Fahgettaboudit is one of the best bicycle locks that you can get your hands on. That’s because it comes with formidable features like a 14mm six-sided chain. This one is very difficult to break through and might be sufficient to keep thieves at bay.

It’s definitely not worth the trouble of getting through this chain if they can move onto an easier target. Protecting the chain is a nylon cover. It’s designed to keep it attached to the bike while protecting both from dings and scratches caused by friction.

The extremities of the chain feature a reinforced disc-style cylinder. The cylinder is made to protect it from drilling or pulling damage. It also features handy double deadbolt locking which gives it more holding power.

The keyhole itself is protected from dust by a sliding cover. This way, you know it won’t accumulate dust and debris over time and will most likely last longer than your average chain lock.

The lock comes with three keys and a built-in light bulb that makes it easy to unlock the bike in low-light conditions. The chain measures 5 feet and it’s a versatile creation that you can use to protect multiple bikes at the same time, granted you have a fixed object to attach them to.

Pros
  • You can register the bike on the manufacturer’s bike theft coverage program
  • Sturdier than most of the other options on this list
  • Features a high-intensity light bulb for use in low light conditions
  • Comes with two spare keys
  • The keyhole is protected by a sliding cover
Cons
  • At 15 pounds, this is a heavy chain

2. Amazer Bike Chain Lock

This bicycle chain lock from Amazer is made for convenience. It’s affordable, easy to carry and use. But, this convenience comes at a price because it’s not the sturdiest. However, it’s still a solid budget-friendly option.

It features a 4-digit combination pad so you don’t need to worry about carrying a key. Another pro about this lock is that it’s made from a medium-length chain. The chain measures only 3.3 feet and weighs about 1.5 pounds which is pretty lightweight and portable.

Yet, it can be utilized to lock other items other than your bike including your ladder and even a gate. Just keep in mind that because of its relatively short length, this bike lock is only suitable for use on a single bike frame and wheel setup. It can’t be used to lock two bikes at the same time.

Our favorite part about the Amazer chain lock is that it’s backed by a 30-day return policy, in addition to a 12-month warranty. This means that if you’re not happy with its performance within 30 days, then you can return and get a full refund. The 12-month warranty mainly covers manufacturing defects.

It’s worth noting that the 0.23 thick and 1.66 long chain links are coated by a waterproof cloth sleeve designed to protect it from coming into contact with the bicycle frame.

Pros
  • Great customer service from Amazer
  • Comes with a combination pad so no need for a key
  • Backed by a 30-day refund policy
  • Comes with a 12-month warranty
Cons
  • The bike lock is fairly easy to break

3. Kryptonite Evolution 10mm Chain Bicycle Lock

Kryptonite is one of the most popular manufacturers of bike components and accessories because they always bring it when it comes to the performance of their products. Their Evolution 1090 bike chain continues this tradition with its 10mm six-sided chain links. They are both heavy-duty and effective at fending off cutting attempts.

That’s because the chain itself is made from manganese steel. The end link is there to keep the chain and the deadbolt connected to one another.

Also included with this model is a disc-style cylinder that promises to withstand drilling attempts, while the nylon sleeve covering the chain helps to keep the chain and the bike frame protected from friction, dings, and scratches.

This is in addition to the sliding dust cover which is positioned on top of the keyhole to keep out dust and debris while extending its lifespan. The best part is that this bike lock comes with two keys just in case you lose one. These are ergonomic “I” keys that come with a light so you can unlock it even in low-light conditions.

Just be sure to register the key with the manufacturer as soon as you get it so that you can qualify to get an extra spare if you happen to lose both.

Pros
  • Comes with a sliding dust protector for the keyhole
  • Protective nylon cover
  • You can get another spare key when you register this lock with the manufacturer
  • It comes with three keys, one of which comes with a high-intensity light bulb for use in low light conditions
Cons
  • It’s not very portable due to its heavy-duty construction
  • It’s a bit expensive

4. Sportneer Bicycle Chain Lock

The Sportneer chain bicycle lock features a 5-digit combination lock which is just a bit more difficult to hack into than your average 4-digit combination model.

Considering the fact that thieves might choose to sidestep the combination lock and go for the chain, you’ll be glad to know that it’s constructed from thick manganese steel. This one has dimensions of 0.27 inches.

Not only that, but this steel is covered with a flexible cloth sleeve which makes it incredibly difficult to cut through while protecting the chain from scratches, dings, and rust.

In addition to promising a long lifespan, this lock is 3.2 feet long. So, you can use it for more than just your bike. It’s useful for locking ladders, toolboxes, and even fences.

Now, while it has a lot of nice features and enough merit to earn it a spot on this review list, this bike chain lock might not be enough to keep thieves at bay in more dangerous areas. But, it’s an affordable option for a daily commuter who’s looking to secure their bicycle during the day in a relatively low-risk area, but definitely not at night.

Pros
  • Lightweight and portable
  • Comes at an accessible price point
  • Features a 5-digit combination pad
  • Multiple locking applications
  • Comes with a lengthy cable
Cons
  • Thin chain compared to competitors
  • It might be difficult to set up the initial lock combination

5. Kryptonite Keeper 785 Integrated Bicycle Lock

This is yet another stellar option from the Kryptonite brand. We swear, this manufacturer is like Kryptonite to bike thieves with these chain locks.

This one comes with a 7mm four-sided chain that’s constructed from manganese steel. It has a unique deadbolt design that helps to reinforce the area between the lock and the chain which can be really easy for thieves to penetrate when it’s not protected.

The lock is designed according to Kryptonite’s well-known disc-cylinder style which is ergonomic as it’s sturdy. But, instead of the usual three keys, you only get two with this model. But, the good news is that both of them are ergonomic “I” keys that you can register to the company’s online safe program so that you’re covered should you ever lose them.

Now, while Kryptonite is known for making sturdy and indestructible bike chain locks that can withstand repeated attempts, this particular one isn’t exactly suited for high-risk areas. We would most likely recommend it for use during the day and even then, only in low-risk areas. It certainly won’t stand up to the type of tools that prepared thieves usually bring to the party.

Otherwise, the chain and the bike’s frame are protected by a nylon sleeve. This sleeve is available in three fabulous colors, including grey, red and purple so you don’t have to settle for the usual black which is also available if you want it.

Pros
  • Comes with four different nylon sleeves
  • Made from manganese steel
  • Released by a reliable brand
  • Available in three colors
Cons
  • The keyhole doesn’t come with a protective cover as would be expected
  • It doesn’t come with the built-in light that comes with other Kryptonite locks

How to Get the Best Bike Chain Lock

We’re guessing at this point in your journey of exploring our guide on the best bike chain locks, you know whether you want a stationary or mobile lock.

If not, then it’s worth looking into both options.

Basically, a mobile lock is suitable for use in everyday applications because you can carry it easily on your bicycle and it’s easy to attach to your bike frame as well.

On the other hand, a stationary chain lock is most suited to a bicycle that stays at home most of the time or one that you only park in low-risk areas.

If you want a lock that does double-duty then you’ll be glad to know that you do have a few options to look into. But, beware; they don’t work as well as locks that are designed to perform only one job.

The most sensible thing for you to do in this situation would be to opt for a two-lock system which means you’d have a lightweight lock that you use during the day and another heavy-duty one meant to protect your bike when it’s parked at night.

Length

The great thing about chain locks is that unlike U locks they enable you to secure your bike to different places. It’s way longer and flexible in comparison.

Longer chains are usually very versatile but they are also heavy and pricey.

Shorter chains are conversely, more affordable, and can do the job of protecting your bike without taking up too much space in your backpack.

For best results, it’s recommended that you avoid using a chain that covers both the bicycle frame and wheels if you want to use a portable chain.

That’s because portable chains mostly secure the bike from the frame and are shorter and lighter as a result. This is what you want with a portable chain. Not only that, but it’s positioned away from the ground and will be difficult for thieves to crop.

Portability

For best results, we recommend wrapping your chain locks around your seat post.

That’s the best way to carry them. Or you could keep it in the included bag which some brands provide.

Ideally, you want to make sure that the chain you purchase will fit on to the seat post of your bike or at least in your backpack or panniers.

Conclusion

Well, as you can see, it doesn’t take much to find the best bike chain lock for your needs.

You just need to know what to look for. But, if we were to go for just one option, it would be the Kryptonite New York FAHGETTABOUDIT Chain.

Thieves can just forget about stealing your bicycle when it’s secured with this chain lock.

It has all the features and components you’d expect from a Kryptonite product, plus you get three keys with built-in lights. You can register them onto the company’s online safe program for increased security.
