How to choose the right lock for your bike? Buying Guide

Choosing a bike lock depends on factors like how expensive your bike is, where and how you use it and how much you can spend on the lock.

Now let us walk you through the steps of choosing the right bike lock for you:

1. The right level of security:

To know your bike’s security level you have to answer the following question.

  1. Where do you live? Is it a big town, city, or university campus? Then it the risk is high. But if you are in a small town or village then the risk is low.
  2. Is your bike attractive? If yes then the risk is high, otherwise you are good to go.
  3. How long do you leave your bike unattended? In this case, more than 1 hour is considered high risk.

If your answer falls on high risk, then you need a lock with a higher level of protection. If your answers are the low risk then a lower security lock can do your work easily.

2. How to know which lock will provide you with your desired level of protection:

Now that you know what level of protection your bike needs, so now is the time to know which lock will provide that protection.

First of all, remember that no bike is unbreakable. A thief with the right tools and enough time can easily steal your bike. But thicker the lock, the harder it is for the thief to break it.

3. Choosing the right bike lock:

You should prefer a bike that is easy to use because if it’s not then you will stop using and get your bike stolen.

So,  choosing a lightweight, and easy to carry lock is important along with choosing a secure and strong one.

Types of locks:

How much security you need for your bike depends on your location and the duration of the bike’s lockup. There are seven types of locks you can get in the market.

1. U-locks:

U-locks are a strong meta ring with the shape of the letter, “U”. The U part is attached to a crossbar section and form the letter “D”. This is why it is also called D-locks.

U locks are the heavier and expensive lock. They are made of hardened steel and requires power tools to cut, which makes them one of the best locks to use for your bike. Hardened steel is a type of carbon steel that has been specially treated in heat. This special heat treatment gives the steel its durability and strength.

Drawbacks of U-locks are that they are difficult to carry and you won’t be able to lock them around bigger objects.

2. Folding locks

Folding locks are great for commuters for their low profile when folded. They enable the user to lock up your bike to objects too big for U-lock or D-locks. Folding locks are one of the popular alternatives to chain and cable locks. Though power drills and bolt cutters can easily compromise their purpose.

3. Chain locks

A chain lock is a lock with a chain, lock, and a key or combination lock. They are flexible and easier to secure around any tricky shaped objects.

Chain and its shackle are made of hardened steel making them durable and secure as U-locks. Best chain locks are also made from a hardened steel alloy. Chain basically have a hexagonal and squares—shaped which are linked together.

They are portable enough to fit comfortably around your waist and a large chain can lock your bike’s frame and both wheels with any tree or posts. Although chain locks are very heavy and expensive.

4. Lightweight locks

Lightweight locks are mostly used in light security situations and they often come in various designs such as zip tie or simple cables. They can be easily defeated by hand tools like cutter and tin snips.

5. Cable locks:

Cable locks are similar to chain locks. But they come with a locking mechanism that’s permanently integrated. They are very easy to carry and sufficient for use in low-risk areas.

Cable locks are made from twisted or braided steel wire in a PVC or other plastic jacket. It comes with an exterior vinyl coating which prevents the steel from corrosion or damage and also prevents the cable from scratching the bike or other surface.

These locks can be easily cut with bolt cutters, but some cable locks also come with overlapping steel jackets threaded over the cable making it difficult to cut the central cable.

6. Wheel locks:

The wheel lock is a ring lock or frame lock having the shape of the letter, “O”. they are also called O lock.

This lock prevents riding the bike and secures the rear wheel. The O-lock is mostly used to prevent theft when a bike is left unattended momentarily.

They have a low-security mechanism that immobilizes the rear wheel by moving a steel bolt through the spokes to prevent motion.

7. Smart locks:

Smart lock uses Bluetooth to allow the bike lock to be unlocked using a smartphone. They also notify when they are breached. Although they are vulnerable to hacking.

Types of locking mechanism:

Bike lock manufacturers use many mechanisms with varying levels of security.

1. Disc detainer:

Disc detainer is also called disc tumbler locks. These mechanisms of locking use a series of slotted rotating discs separated by washers. These discs has a cutout and when locked, the cutouts don’t line up but by inserting and turning the key, rotated them into alignment to form a channel. A sidebar also rests against the discs which prevent you from turning the lock when there is no channel.

The disc detainer lock only opens when each disc is aligned to a relatively precise position.

2. Slider:

A slider lock mechanism is when a key is inserted, it actuated a series of springless sliders within a plug that corresponds to a slot on the outside of the plug. In the slot, atop of the slider is a sidebar which falls into the slot before the lock can turn. When the key is inserted, the slide comes in the correct position, the sidebar falls into the slot and the plug turns within the cylinder.

3. Pin tumbler:

This lock has a plug within a cylindrical housing and this plug and housing contain long pin chambers that allows a series of pins that are spring-loaded to move back and forth between the plug and the housing. When locked the pin sit right in between the plug and housing and when the key goes into the plug, it lifts up the spring-loaded pins so that they move completely into the plug or housing and leave a gap in between allowing the plug to turn.

4.  Wafer:

Wafer has the same mechanism as a pin tumbler lock but instead of using spring-loaded pins, it uses spring-loaded rectangular wafers.

When it comes to weight, transportation, storage, and flexibility, the cable is definitely better. But what about safety? Unfortunately, not too good! 

Any basic cable locks can be picked or unlocked easily, and some high-quality cable locks are safe but they cost a lot. Again some basic bolt cutters, grinder, or wire cutter can easily break and cut through the cable lock.

In the case of security, U-locks are the boss of all. They are big, strong, hefty. Most of the U-locks requires heavy-duty cutters or even power grinders to get through.

Can my lock be picked?

Eventually, all locks become defenseless against cutting and all bike locks can also be picked. But nothing to worry about as most of the modern locks can’t be defeated by amateurs. Most of the locks found today, are very secure and need professional tools to breach.
