Top Ten Best Bike Locks For 2021

A bike lock that cannot be broken doesn’t exist, but there are several reasons why you should invest in a high-quality lock for your bike. With the right lock, the risk of someone stealing your bike can be significantly reduced. U-locks are popular products, and they serve as powerful deterrents against theft.

A U-lock can resist chisels, hammers and blunt objects, but the horseshoe design can be quite limiting. If you decide to purchase a U-lock, it’s important to apply it in a way that limits the amount of leverage available to a potential thief.

In other words, the lock should be sized in a way that reduces the open space between the lock and surrounding objects. The second major option is a cable lock. Although cable locks are much more adaptable and versatile than some of the alternatives, they don’t offer as much protection.

Unfortunately, a pair of bolt cutters can be used to cut through most cable locks. If you’re planning to leave your bike in a low-crime area, then a cable lock might give you an acceptable level of protection. The third major option is the chain lock.

Many bicyclists choose chain locks because they’re strong enough to resist chisels, hacksaws and tools used for theft, but if you choose to use a chain lock, make sure to buy a padlock that offers a similar level of protection.
