Whether it’s a laid-back cruiser bike or a rugged mountain bike, riding a bike is one of the best ways to experience the outdoors, commute, skip traffic and avoid crowded public transportation. Bikes are excellent means of transportation, great exercise and a great investment for anyone looking to cut back on their carbon emissions. The tough part about bikes, however, is they’re very easy to steal. Bike thefts skyrocketed during the pandemic, with Bike Index estimating a 26% jump between 2019 and 2020, partially due to the increased numbers of bike riders across the country. Whether it was to avoid crowded mass transit or to enjoy a socially-distanced afternoon with friends, riding bikes became a common hobby, and thus bike thefts became a more common occurrence. If you’re like me and recently invested in a brand new bike you’re jazzed to hit the pavement with every weekend, then it’s time to invest in a U-lock as well.

How to Pick the Right Bike Lock

Picking the right bike lock is a lot like picking the right bike. You want to assess your lifestyle, locking habits, riding habits and how good you are at keeping track of keys. There are essentially three different types of bike locks: chain locks, wire locks (also known as flexible bike locks) and U-locks. While chain and wire locks have shapes that are easier to maneuver, U-locks are thick AF and much harder for thieves to steal, so long as they’re made well.

Things to Consider About U-Locks

U-locks are pretty much exactly what they sound like. They’re u-shaped bike locks that typically use a key to lock and unlock. They’re sturdy and hard to cut through, but not impossible unfortunately. There’s never a guarantee some thief with all the right tools won’t come along and saw right through, but there are some locks made better than others.

The benefits of using a U-lock include:

  • Since many of them use a key to unlock, there’s no need to remember or protect a combination
  • They’re made thick, durable and hard to cut through
  • They’re portable and easier to carry than some chain locks, which can be quite heavy

The downsides of using a U-lock are that the shape is rigid, and depending on the size of the lock you might not be able to fit it around your bike and any regular lamp post or piece of street infrastructure. However, for the most part, they’re built to wrap around bike racks, skinnier lamp posts, fences and more.

Kryptonite is one of the best U-locks in the biz, and for that reason you’re probably going to see a few of their locks in this list.

It’s got 13mm of hardened steel shackle that resists all sorts of tricks and tools like bolt cutters and leverage attacks. The cable is 4′ long so you’ve got plenty to work with to lock it up, and they’ve got a key safe program where you can send a new key to yourself anywhere in the world, in the event that you lose one.
