A bicycle is a useful thing. Whether it’s part of your daily workout, a convenient way to get around town or your daily commuting vehicle, if you own a bike and ride it regularly, you likely understand how important this mode of transportation can be. Perhaps, that is the reason why it causes so much hurt and anger when a bicycle is stolen.
Bicycle theft is a surprisingly common problem, and it’s always better to prevent a problem than to cure it. The best course of action is ensuring you have the best bike lock to keep your bike secure when you’re not with it.
Choosing the best bike lock for you depends on a number of factors. First, it’s a good idea to consider how widespread crime is in the area you are looking to secure your bike. If it’s behind a locked gate or inside a garage with CCTV, that in itself may deter many thieves, meaning a cheaper lock may suffice. However, if you’re looking to leave your bike in a dark alley overnight, it’s probably worth picking the most intimidating lock available. After assessing likelihood, you can think about convenience, what style of lock you’d prefer, if you need a key or combination and how much weight you can carry.
To make understanding the types of locks easier, have a read through our breakdown and see which one appeals to your needs.
The Best Types of Bike Locks
From chain locks to U-locks, these are the most popular types of locks on the market.
These locks look like a normal chain you could see anywhere, except they’re usually supersized. Their chunky build quality adds an extra dimension of protection for your bike. In addition, the chain’s flexibility provides versatility for different tasks and can be easily stored around the frame of your bike without a fixed bracket. The downside of a chain lock is that compared to other options, they tend to weigh more.
Much like chain locks, wire locks provide an impressive amount of flexibility and versatility. However, they tend to be smaller and lighter than their linked counterparts. While this trade-off does provide a number of benefits, these locks do tend to be more susceptible to theft. Depending on the thickness and quality, these are often the most budget-friendly lock style available.
A U-lock is another option that sports an aptly descriptive name. These tough locks are, as expected, U-shaped and include a bar that fits over the two open ends to secure the lock. The benefit of this style of lock is that it combines toughness with portability, offering a nice balance of the two. These locks usually come with a frame-mounting bracket and sometimes include an additional wire which can be used to further secure your bicycle.
The Best Lock Styles
There are two major bike lock styles, combination and key locks. Read on for an explanation of those styles.
The major benefit of a combination lock is that it’s never necessary to carry anything extra to open the lock. This means, as long as you can remember your number (or letter) code, you can open the lock. This is a great option for anyone who may want to share their bike with others or for those who are particularly prone to losing keys. However, these benefits do come at a cost. Should your code be seen or left in place, it will be no trouble at all for any thief to release the lock and take your bike.
Like those found on most doors, key locks are probably the most common way to open and close a lock. Most of these locks come with at least two keys. This means, outside of a person cutting or picking your lock, no one can open it apart from you. Furthermore, with two keys, you’ll be able to keep a spare in a secure place should the worst happen and you misplace one. The fact you can lose the keys is the one big downside to buying a key lock. The last thing you want is to become a thief-look-alike while trying to cut or saw your way through your own lock.
Below, you’ll find 19 of the best bike locks available. From combination chain locks to keyed U-locks, there’s something for every preference. Buy one to keep your bike secure when you’re not around.
