Buyer’s Guide: Best Bike Lock

  • Many factors affect the choice of a bike lock. When you want to select a bike lock, you will consider where you will be using the bike and its cost. These, among other factors, can guide you in the choice of a suitable bike lock.
  • Here are essential steps to guide users through the process:
    • The Best Security Level

      Here are vital questions you need to answer before knowing the security level of your bike:

    1. What is your location? Is the place a huge town, a university campus, or the city? If you answered affirmative, the risk is high. People living in small villages or towns, on the other hand, have a low risk.
    2. Do you have an attractive bike? Without a doubt, the risk is high if yes. If not, you might not have to worry excessively.
    3. The period you leave your bike unattended to also matter if you leave it for over an hour; this is a high risk.
    4. For people within the high-risk bracket, they need a strong lock with a superb protection level. On the other hand, you might not need a sophisticated lock if your answers are low risk.
  • How do you know the lock that will give the intended protection level?
  • With an idea of the right protection level that your bike needs, the next step is to consider the best lock to serve that purpose.
  • The first thing you should bear in mind is that all bikes are breakable. All it takes a thief is the right set of tools and time to steal a bike. However, with a strong lock, the thief will have a terrible time trying to break your lock.
  • Choosing the Ideal Bike Lock
  • Even though you need your bike lock to be strong and sophisticated, you also need it to be easy to use, as a complicated bike lock can discourage users to the extent of abandoning it.
  • Type
  • There are various types of bike locks, and the type should be a factor in the crime rate in your vicinity, as discussed above. Basically, bike locks fall into four categories, which are
    • U-locks
    • Chain locks
    • Cable locks and
    • Folding locks
  • These various locks come with their pros and cons.
  • However, the major determinant of the type of bike lock you should consider is your vicinity’s crime rate. This is why a simple cable lock will be good for you if you live in the suburbs with a lower crime rate.
  • Someone living in the heart of the city, for instance, will be better off with a stronger and sophisticated bike lock like a U-lock, which is more secure.
  • Security Rating
  • This involves the security level you need to give you peace of mind.
  • In deciding the security ratings, you will need to consider some major factors which will guide you towards getting the best bike lock that will serve you.
  • Besides considering the crime rate in your vicinity, the value of your bike also matters. Also, the period of time you will spend away from your bike where you are also matters.
  • After answering these questions, it will give you an insight into the security level you desire. It will also guide you with an idea of the best lock system that will work for you.
  • Another trusted way to determine the bike lock’s security rating is to estimate the security ranking from online security tests. This will give you an idea of locks that fall within your preferred security scale. While these tests’ accuracy is yet to be proven, they can serve as a pointer into the best bike locks you can use.
  • Brands
  • With the idea of the security level you desire and the type of lock that will suit you, you can narrow your search down to the brands. There are brands that have made themselves a household name in the manufacture of bike locks. This makes the brand reputation a big consideration in selecting a bike lock.
  • Some of the best bike lock brands are Kryptonite and Via Velo. Although, your final choice of bike brands should be exactly what you need.
  • Material
  • Almost all locks out there can be defeated. However, what makes the best lock stand out is how difficult it will be to break. In other words, your lock should give the thief a hell of a time when trying to steal your bike.
  • This makes various factors such as the material hardness, thickness of the construction, etc., matter when deciding which lock will be suitable for your bike. An idea of the tools a thief will need to break a bike lock will also help.
  • One of the most common tools they use is a bolt cutter.
  • People that live in places with an alarming crime rate should go after a lock with a diameter of at least 14 mm, ideally in the range of 13 mm to 15 mm. It will not make it easy for the thief to break such a lock. Making the lock impregnable to a bolt cutter is essential. As a result, you are better off going with locks with 16mm diameter or more.
  • This makes the lock diameter one of the essential things to consider to resist a bolt cutter-also, the strength of the steel matters. Besides, consider the lock design and the locking mechanism used to hold the piece.
  • These are important factors that affect the strength and security your lock will provide.
  • Size
  • When it comes to the best bike lock, size is a relative term as it could point to various things.
  • For some locks, size can refer to the lock diameter, while for a U-lock, the size refers to the area within the lock.
  • Typically, for a U-lock, a smaller lock gives a pretty secure lock. It is more secure because it will give the thief a tough time to lay their hands on various parts of the lock.
  • For other types of lock besides U-lock, the lock’s size is more about the thickness and size of the lock. A thick lock will definitely make it harder for thieves to break it, which makes it the ideal choice.
  • Bike Locks and Forms of Locking Mechanisms

  • There are various mechanisms that appear in bike lock with series of security levels:
    • Disc Detainer

      Disc Detainer is the same as disc tumbler locks. This is a locking mechanism that employs several rotating discs slotted and separated by washers. The set of the disc comes with a cutout that un-align when locked. However, when you insert and turn the key, it rotates them into an alignment, forming a channel. There is also a sidebar that rests against the disc, which stops the lock’s turning without a channel.

      This type of lock needs a perfect alignment of the disc to a precise position before the lock will open.

    • Slider

      When a key is inserted into a lock with a slider mechanism, it triggers a series of springless sliders inside the plug that looks like a slot outside of the plug. There is a sidebar inside the slot on top of the slider, which must get into the slot to trigger the lock’s turning.

      Inserting the key sends the slide to the right position while the sidebar falls right into the slot, and the plug is inside the cylinder turns.

    • Pin Tumbler

      This lock comes with a plug housed inside a cylindrical housing with a plug and housing that comes with long pin chambers, which gives way to various spring-loaded pins to have various movements between the housing and the plug.

      In the locked position, the pin will be between the housing and the plug. When the key enters the plug, it shoots up the spring-loaded pins to let them move into the plug or housing completely, with a little gap between them that allows the plug to turn.

    • Wafer

      The locking mechanism of a wafer is the same as a pin tumbler. It, however, does not use spring-loaded pins but rectangular wafers that are spring-loaded.
