Are you a bike commuter locking to a rack or a beach cruiser tying up to palm trees? Are you pedaling a vintage road frame through the park or a fixie through crowded city streets? To help keep your ride secure, we unlocked the best bike locks, so read on to see which is the right one for you. Best for Big Cities: Kryptonite New York Fahgettaboudit Chain Courtesy of Amazon.com Buy on Amazon New York City’s bike thieves are notorious for their tenacity, innovation, and occasional use of power tools. This chain and U-lock system earns its right to invoke the toughness of Big Apple bike messengers with 39 inches of 14 mm, six-sided, manganese steel chain held tight with a 15 mm steel shackle. Kryptonite’s patented oval hardened steel crossbar and a double deadbolt lock can’t be jacked open and this steel isn’t going to be drilled. The chain is sheathed in a durable nylon cover to protect your paint, and one of the three keys has an integrated high-intensity light for all-night safety. Best Budget: Kryptonite Kryptolok Series 2 Courtesy of Amazon.com Buy on Amazon At about $30, this classic Kryptonite Kryptolok Series 2 is the most security bang for your buck. Use the U-Lock on its own for quick rack lockups because the 13 mm shackle is more than strong enough to hold up against most bolt cutters. For longer lockups or high-theft zones, bring the 4-foot KryptoFlex cable for securing the front wheel. It also comes with an improved FlexFrame-U transportation system, which allows for multiple mount positions on your bike. Best Mini: OnGuard Brute Mini Courtesy of Amazon.com Buy on Amazon Quick lockups are a cinch with the OnGuard Brute Mini U-Lock because of a TriRadius shackle that is tough but still allows for multiple locking options. OnGuard’s X4P Quattro locking mechanism provides four-sided protection from drills, bolt cutters and even saws. Throw it in your backpack, or mount it to your bike with the Snap Lock Quick Release bracket. It comes with five keys, one of which has an integrated micro-light for added safety. Best Value: Kryptonite Evolution Series 4 Disc Lock Premium Pack Courtesy of Amazon.com Buy on Amazon Kryptonite’s Evolution Series 4 Disc Lock is a burly 14 mm steel shackle and double deadbolt lock that resists bolt cutters, pry bars and jacks. Meanwhile, the disc-style lock cylinder is reinforced with anti-drill steel. Includes a nice carrying pouch and disc lock reminder that will easily fit in a pack or under the seat. Best Messenger: Kryptonite Messenger Mini+ Courtesy of Amazon.com Buy on Amazon The simple innovation in this bike lock was manufactured with input from a fleet of New York City bike messengers. They needed a lock that was tough, light and easy to take on and off. The Mini U-lock is a light, 11 mm shackle that adds an 11 mm wheel extender for secondary protection for your front or rear wheel. The crossbar has a reinforced cuff for pry-resistant durability and the DuoCore cylinder is tough to drill. The stainless steel keys come with coiled wrist key chains so you can keep it on you all day. Best Design: Hiplok Chain Lock Courtesy of Amazon.com Buy on Amazon Bike commuters and messengers have long worn their chains around their waist or slung over their shoulder, but it’s rarely a comfortable option. Enter Hiplok, a British firm merging security and fashion. This lock system integrates a burly chain into an adjustable belt that allows you to wear it comfortably around your waist like a belt. It comes in four colors, but your best bet is to go with black — it matches everything in your wardrobe. Best Innovation: Master Lock Street Cuffs Courtesy of Amazon.com Buy on Amazon Lock up your bike with this innovative cuff system. Master Lock has engineered a pivot into each cuff for easy lock up around both the bike and the rack or pole. Heat-treated laminated steel construction and ratchet-tight locks protect against most bolt cutters, pry bars and jacks. Soft touch bumpers protect your paint, and they fold in half for easy storage on your belt loop or attached to your messenger bag. Best Lightweight Lock: TIGR Lightweight Titanium Bicycle Lock & Mounting Clip Buy on Amazon This isn’t your traditional-looking U-lock, but the sleek, minimalist take on the common design sees far more improved aesthetics — as well as a high level of security — thanks to its titanium build. It’s a mid-security lock, so it might not hold up in super high-crime areas, but it should hold its own in areas where bike thefts aren’t rampant. The other great thing about titanium? It’s super-lightweight, which means this lock weighs less than a pound (.9 lbs., to be exact). Despite the fact that the 1.25-inch lock looks like it would scratch up your bike frame, there’s PVC coating on the lock to prevent that. There’s also a mounting clip for the frame, so you don’t have to tote it in your bike basket or bag when you’re on the go — instead, just snap it handily into the clip. Plus, for those who aren’t great at remembering lock combos, this lock uses a key, so you can just attach one of the two included copies on your keyring and go. Best U Lock: Kryptonite New York Standard Heavy Duty Bicycle U-Lock Buy on Amazon This heavy-duty bike lock was born following a rise in bike thefts in New York City — and that was 14 years ago, so you know it’s held its own over the years. It takes double the amount of trouble to break into, thanks to a locking mechanism (patent pending) that’s secure on both ends so you have to cut twice if you’re trying to break in. In fact, it seems designed to make dismantling the lock so frustrating the would-be thief will just give up: The diameter of the lock’s “U” is a bit larger than what’s standard — and the steel a bit more durable to thwart bolt cutters (the makers say that the cylinder is both pick- and drill-resistant). We also love the details of this lock: One of the three keys comes with a tiny LED light so you can see well enough to unlock the bike in the dark, without trying to balance your iPhone’s flashlight in the other hand. Like many locks, it also comes with a frame mount for easy transport when you’re riding. Best Chain Lock: Kryptonite New York Noose 1275 Bicycle Chain Buy on Amazon At 7 pounds, this lock isn’t exactly light, but with a gold rating from Sold Secure and four stars out of five from the ART Foundation — enough to qualify it as secure in high-risk areas — rest assured that your bike is secure with this clever lock. The weight of it seems like a lot for its relatively short size (just 30 inches), but that’s due to one of its main security features: 12mm hardened manganese steel links, which are so strong that you’d have to use the largest, strongest bolt cutters available to get through them. This means, according to the manufacturer, that this lock is drill- and pull-resistant — and like the very best locks, it’s double-bolted, so two cuts are required if you’re planning to make off with the bicycle. The chain lock also features a clever design. Its noose locking system means you simply thread one end through a loop at the end of the other side of the chain — yoking it tightly to something like a bike rack or pole — rather than forcing the two ends to meet in order to lock it. Best Cable: Master Lock 8143D Self Coiling Cable Lock Courtesy of Amazon.com Buy on Amazon Crusin’ in resort towns? Pedaling through wine country? Riding with your kids in the park? For five bucks you can tether your rig with four feet of Master Lock’s 5/16-inch braided steel. It’s coated with a protective vinyl so it won’t scratch your paint job. Keyless entry is convenient — just don’t make your code 1234.
