If you live in a city, then you know the anxiety that comes along with riding a bike. But worrying about how to secure your bike shouldn’t be one of your concerns.

We’ve all seen bikes left outside that have been scavenged and stripped for parts—or, even worse, the ones stolen and ditched somewhere along the way. I recently found an amazing vintage bike out with the trash, and after fixing it up for me, my boyfriend made sure I was all set with the type of lock I could trust, no matter where I was locking up.

After researching thousands of reviews on Amazon, we compiled a list of thebest bike locks you can get to keep your head and eyes on the road, instead of worrying about bike thieves.

Editor's Note:

The recommendations in this guide are based on thorough product and market research by our team of expert product reviewers. The picks are based on examining user reviews, product specifications, and, in some limited cases, our experience with the specific products named.

Kryptonite New York Standard Heavy Duty Bicycle U-Lock

Kryptonite is well known for their heavy-duty bike locks, offering a bevy of options to keep your bike safe. Reputed to be the best bike lock from Kryptonite, the New York Standard is a heavy duty U-lock with three keys, one of which includes a handy replaceable FOB light for use in the dark.

Made of 16-millimeter hardened max-performance steel, this lock is super heavy-duty and is said to have survived crowbars, hammers, and even a hacksaw. With the option to enroll in Kryptonite’s anti-theft protection program, you can have the peace of mind that if your lock fails, you can lean on some reimbursement for a new bike.

It should be noted, though, that the lock has to be left behind in order for Kryptonite to honor the program. And it requires registering your vehicle's serial number with Kryptonite first. If you’re prone to misplacing things, like I am, then you’ll love the Kryptonite Key Safe Program, which means that Kryptonite will ship your first two keys for free, in the event that you lose them.

Like some other bike locks, reviews mention that the lock jams frequently, but we wouldn’t let that deter you from purchasing one.

Pros

  • Withstands a lot

  • Key safe program

Cons

  • Expensive

  • Lock might jam

Abus Ivera Steel-O-Flex 7200/85

The Abus Ivera Steel-O-Flex is a flexible lock and chain that makes it easy to lock up in a variety of situations. It has 22 mm hardened steel shackles to protect the inner steel cable. This also means that the lock won’t damage your bike or rust when left outside.

The Abus lock comes with two keys so you can keep one somewhere safe. But the keys are said to jam from time to time, so you’ll want to keep that in mind when locking and unlocking your bike.

With real security comes some bulk, and reviews mention that this lock is a bit heavy, which can be annoying to bike with unless you can toss it in a bag or backpack. We’d suggest using the Steel-O-Flex with an additional U-lock for extra safety.

Pros

  • Heavy-duty protective coating

Cons

  • Bulky when riding

  • Key may jam

Kryptonite Kryptolok 12.7 mm U-Lock

Another fantastic lock from Kryptonite, the Kryptolock is a 12.7-millimeter U-lock with an additional 10-millimeter looped cable for additional strength. This lock is great if you want an extra level of security, and it can be easily looped through your wheels.

As is with other Kryptonite bike locks, the Kryptolock also comes with the Key Safe program in case you misplace your keys and you have the option to enroll in the anti-bike-theft program. One review of the Kryptolock mentions that the lock actually broke the attempted robber's crowbar and stayed in pristine condition.

People are fans of the double deadbolt, because it means that someone would have to make two cuts instead of one in order to steal your bike. Kryptonite even has a chart to help you pick the best bike lock for your security needs, in case you want some extra peace of mind in your decision making.

As is with other locks, the keys might stick in the lock from time to time, but this doesn’t seem to be a huge issue with this one. What we love about this lock is that it comes with a mount for easy storage while you’re riding your bike.

Pros

  • Double deadbolt lock

  • Mounts to bike for storage

Cons

  • Key might stick

Product image of Sigtuna Bike Lock
Sigtuna Bike Lock

The Sigtuna bike lock is a great, inexpensive alternative to other bike locks on the market. Included with the 16-millimeter high-performance steel U-lock is a four-foot cable for extra security.

While this bike lock is a little bit heavy, it does come with an easy to install bike lock mount, making it easy to store when you’re out on your adventures. Despite the low price of this bike lock, the reviews offer high praise. But this bike lock does have a lock of reports of the lock jamming, so keep that in mind when you are deciding on whether or not a deal is worth it.

Security reviews mention that the Sigtuna bike lock is great when matched up against bolt cutters as well as a drill so if you don’t mind a lock jam every once in a while this really is a great option.

Pros

  • Comes with 4 ft cable

  • Affordable

Cons

  • Lock may jam

Via Velo Bike U-Lock with Strong Cable

The Via Velo bike lock comes with both a U-lock and a six-foot cable lock. This lock is great for all weather due to its PVC covering and the hard lock cover to protect the keyhole from potential rust.

Sturdy but not cumbersome, it’s easy to click your lock into the bike lock mount and tuck it away during your rides, though some reviews mention that they’ve had a hard time finding a spot on women’s bikes. Boasting a smooth lock and unlock, the Via Velo is my personal favorite and I worry less knowing that my bike is protected by the Via Velo lock.

Included in your purchase is a three-year warranty, and reviews mention that the customer service is fantastic. One person had an issue with their key not working and the issue was fixed for them within days. The Via Velo bike lock is great for people with mountain bikes, or bikes with bigger frames that have to leave their bike out for long periods of time, and even e-bike riders are pleased with the functionality of this bike lock.

Pros

  • Affordable

  • Easy lock mounting

Cons

  • Might be tricky to mount lock on some bikes
