Things to Keep in Mind While Buying Unbreakable Bike Locks
There are a lot of different bike locks available in the market. In this list alone, you must have noticed a wide variety. This is why before you set your heart on one of these locks, you need to keep in mind a couple of factors.
These factors can help you better understand which of these bike locks is better suited for your bike and help you make an informed decision. The following are some things for you to keep in mind when buying an unbreakable bike lock:
Type
The first thing you should decide is what type of bike lock will be most suitable for your bike. There are U-locks that have been used traditionally due to their robust construction and reliability. However, the drawback is that these are usually heavier and a hassle to carry around.
Another common type of bike lock is the cable lock. These usually provide you with more freedom as they are flexible and can be wound easily against any railings. The drawback is that they don’t always provide the highest degree of cut resistance.
You can also find folding locks that provide a higher degree of flexibility. These days there are even combination locks that combine the best of multiple types of locks. Similarly, even in terms of locks, you need to look into whether you prefer a padlock version or a combination lock.
Size
Size is an important thing to consider when it comes to bike locks. You want to ensure that the lock you choose can fit tightly around your bike frame or wheel. This is usually difficult when it comes to U-locks as you may find your options limited in case you want to lock your bike to a lamp post.
With a cable lock, ensure that you choose a length that is long enough to provide a comfortable distance but also is a snug fit to prevent rattling.
Protection
While having a stainless steel design is great, what is not great is having to hear a constant rattling noise. Furthermore, this rattling can lead to scratches on your shiny bike. These days most locks come with a polyvinyl chloride coating which helps prevent this. Some rocks even offer a rattle-free mounting bracket.
Tips to Lock Your Bike Properly
To truly ensure that your bike remains safe from any thieves, there are a couple of additional steps you can take. Once you purchase one of these bike locks, here are some tips on how to properly lock your bike:
- Always choose a more crowded area when locking your bike.
- Do not lock your bike through the wheel. Always tie the lock to your bike frame.
- Choose to lock your bike where there are other bikes parked.
- Avoid locking your bike to trees, signposts, or wooden posts. Opt for railings and other sturdier objects that are not easily moved.
- Try to lock your bike in an area with CCTV coverage.
- Keep your locks in an elevated position to prevent easy attacks from hammers.
- Make sure to keep your locks as tight as you can with minimal interior space.
FAQs on the Best Unbreakable Bike Locks of 2020
The short answer is no. Even the strongest bike locks can be broken into with enough time and tools. So what is the point of this list? Well, it is to make stealing it more time-consuming and overall more difficult. The varying components and build try to ensure that these locks cannot be broken into using traditional techniques and tools.
How thick a bolt cutter can cut into largely depends on the size and quality of the bolt cutter itself. It also depends on the material that the bike lock is made from. Typically, a $20 bolt cutter can easily cut cables and padlocks up to ⅜ inches thick. However, depending on the build, some locks can withstand much heavier attacks.
Combination locks tend to be more difficult to pick, as they need to be cracked. The exception to this is luggage combo locks which tend to be fairly easy to crack.
There are many bike locks that can provide a high degree of protection despite flaunting a lightweight build. However, the sturdier locks tend to lean to the heavier side as they will include a lot of stainless steel in their construction.
