What Types of Bike Locks are There?

Now we have covered the best bicycle locking systems and compared them, it’s good to know there are a lot of different types on the market too. 

Chain locks

Chain locks are like the locks we compared above, they are good for theft protection and can be portable depending on their weight.

These chain locks however are not as powerful as U or D lock systems which use a shackle. 

Cable locks 

Cable locking systems are lightweight options which are good for transporting, allowing you to use them on the move, take on commutes and even wrap around your waist like a belt. 

However, these locks do tend to be very easy to cut with an angle grinder or another tool, so even though they may earn you freedom, your bicycle is not as protected as if you used other locks. 

U locks or D locks

These are the most durable locking systems on the market, most have a sold secure gold rating and use a small U design which reduces the space between your bicycle and the lock, this may earn you more time before your bicycle can be stolen.

Folding locks 

Folding locking systems are your best bet if you like to take your bike on adventures, not only are they lightweight and compact for transporting, they also have the ability to be locked onto a variety of different awkward places.

Why Is a Bike Lock Important?

Having a bicycle lock is so important, whether you are using Kryptonite locking systems or heavy duty U shaped shackle locks, having that extra layer of security on your bike can save you worrying and a lot of money in the long run.

CHECK THE CURRENT PRICE

This is especially important in high crime or city areas, having a lock deters thieves to find an easier option to steal. 

However, it must be noted that every locking system is breakable, so it’s important you invest and choose the best model possible so as to give your bike a higher chance of protection against being stolen.



Best Features to Look Out for In a Bicycle Lock?

As you already know, choosing the best locking system for your bicycle is very important, as this can be the deciding factor between a thief leaving your bicycle alone or taking it with ease. 

There are some key things to look out for when choosing your model, whether it’s a Kryptonite evolution series 4 or Abus granit system, you need to ensure you are getting the right amount of protection needed.

Casing or sleeve

The top models should have a protective casing over their links or be made of high quality materials to stop your lock damaging or scratching your bike. 

These can also come in bright colours to deter thieves or soft housing to prevent it damaging other things when storing.

Is it thick enough?

The thickness of your bike lock is an important factor to consider when purchasing, this will ultimately determine how easily a thief can break into the lock. 

Cable locks can be easily cut with bolt cutters, while U-locks and chain locks with thick links, body and shackle can withstand these cutters, such as the Kryptonite New York model on our list. 

How much does it weigh?

The weight of your bicycle lock will determine how you use it and how often you use it. If you are looking for a lock you can take with you all the time on commutes then don’t go for something too heavy. 

If you are looking to use it for stationary purposes only then choose a heavier weight, this can often offer more heavy-duty security too. 

Size 

Just like the weight, the overall size of your model matters. If your security locking system cannot fit around your bike or whatever you are locking it too then it’s pointless! 

Ensure you pick a tight-fitting lock to reduce space for thieves, make sure there is little room between the shackle and your bicycle.

Reviews 

It may sound obvious but you really need to look into the reviews before purchasing your lock. A product may be of high quality and look nice on paper but if it doesn’t last in the real world it won’t last on your bike either! 

Check for points such as an easy locking mechanism or a sold secure gold/silver rating. 


Type of opening

You should consider what type of locking mechanism your model uses. There are options of using standard keys, combinations or electronic locks. 

Keys

Using keys is better than forgetting a combination to your lock, you can even keep spare sets around in case you lose one. 

However it can be very annoying if you forget them. 

Electronic

Electronic locks for your bike are great technology wise, you can even connect them up to your phone or get them to sound off alarms. 

Downfalls of these locks however are their very expensive price. 

Combination

These locks are great options if you are someone who forgets keys often, however the design can be broken quite easily and common combinations can even be guessed. 

Rating

We touched on ratings previously within our review section earlier, theses are the different ratings that bike locks on the market can have. For example, there is; bronze, silver or gold. 

These locks are all tested by a company called sold secure and then rated accordingly. 

Gold – can withstand over 5 minutes of trying to be broken into with a variety of tools offering the highest security. 

Silver- can withstand 3 minutes and offer medium security

Bronze – can withstand one minute and offer the lowest security protection for your bicycle. 

You should check for these ratings depending on your make of bicycle and how often you leave it. For example, if you live in a city area,  your bicycle model is expensive and you leave it for longer than an hour then you should get a gold rating lock and vice versa for a silver. 

Cost

The cost of your locking system will ultimately depend on how much security you want. If you can spend more you will get a better locking system that can offer your bicycle more security such as an Abus granit model, a cheap budget will get you a less reliable lock, thus offering a lower level of security for your bicycle.


Tips For Anti-Theft Protection

Now as you must know, all locks can be broken into with the right amount of persistence and power tools, however there are also some other practices we can be doing when leaving our bicycle to help reduce the likelihood of theft.

Don’t park it in the same place!

If a thief sees your bicycle repeatedly in the same place at the same time every day they are going to workout the best times to nick it. 

On the other hand if you try to keep it locked up in a variety of places its unlikely a thief will be able to know how long you will leave your bicycle unattended for. 

Using a GPS

Nowadays there are neat little tracking devices that you can hide on your bicycle’s handlebars. This is great for tracking your bicycle if it gets stolen and can be used by the police to find your bicycle. 

This is worth investing in if you have a popular model of bike.

Use more than one lock

Try doubling up on your locks, a U-lock and a combination for ultimate security. This makes your bicycle look unappealing to thieves due to the lengthy process of trying to steal it! 

For max results use one to secure your frame and one for your wheel. 

Double check

After locking your bicycle, always double check it to see if it’s actually locked, sometimes when we are in a rush we can do these things mindlessly and this would be a big price to pay! 

Register 

Register your bicycle at your local police station, this a great way to find your bike if you ever need to, due to its model and name being registered to you to begin with. 

Leave little space 

When locking up your bicycle try to leave little space in between the lock and your actual bike, this makes it harder for thieves to use tools such as crowbars, and they are more likely to move on from your bicycle than spend the time trying to break into it.

Park it with others 

Do not park your bicycle in a place with limited people, isolated areas or backstreets are high targeted areas for this kind of crime, instead keep your bike parked with another bike! 

This reduces the likelihood of theft and makes your bicycle a less likely choice too due to the amount of other bicycles parked with yours. 

Don’t take any risks

Don’t leave your bicycle parked outside overnight, don’t leave it for two minutes while you pop in the shops. 

It’s not worth it, if you take these risks then it’s likely your bike will get nicked within a matter of seconds one day, always lock up your bike no matter how small of time you’re planning to leave it for. It’s better safe than sorry!


The Proper Way To Lock Up Your Bicycle

Now you know to make your bike look less appealing by parking it with a lot other bicycles, there are also ways to actually lock your bike properly which can deter thieves too. 

Put the U-lock through the back wheel 

By using this method of putting the U-lock through the back wheel and the inside rear triangle of the frame, you end up being able to lock the frame and the wheel without actually having to lock the frame, this is because it’s impossible to pull the frame from the rear wheel. 

Secure the front wheel with a second U-lock

This will ensure maximum protection, you can just put a cable or chain lock on the front instead but a U-lock offers max security. However it must be noted this can prove heavy to carry around, so we would only use this method for very unsafe areas or if you had to leave your bicycle for a prolonged period of time. 


FAQs

What is the best type of locking system to buy?

The best bicycle locking system has to be a U or D lock, these locks can be opened with only one key and reduce the proximity between the lock shackle and your bike, making it a tiring option for thieves, some notable brands that offer this are Abus granit and Kryptonite locks.

Next up are chain locks, these can be combined for ultimate protection with a U-locking system and are great if they have wide links. 

Even if I get a lock, I’m still concerned my bicycle may get stolen? 

Unfortunately, thieves are always there, however if you use two locking systems at once and follow our tips above you can reduce the chance of this happening to your bike greatly.

Remember, keep your bike parked with others and never leave it unlocked, even for a minute!

Is there an unbreakable locking system? 

No, every model is unfortunately breakable, however they differ in how long it can take a thief to break into them. The longer it takes, the more likely the thief will move on and leave your bicycle. 

A pretty nearly unbreakable brand to look into would be the Kryptonite locks or Abus granit model which are sold secure gold rated. 

How can I keep everything else on my bike safe? 

You should take your lights and other accessories such as your saddle with you, these are easy things for thieves to take. 

Wheel wise you can consider buying locking axles or anchors to prevent your bicycle from being able to be moved forward. 

How can I know how strong a bicycle lock is? 

Go for a thicker model with a good rating. A thicker model will mean a strong lock and links, look for lock diameters ranging between 14 mm and 16 mm, these will require very large bolt cutters and will be tiring to try and cut through. 

Where should I lock my bike for safety?

Lock your bicycle with other bicycles or even next to better looking ones, thieves won’t go for your bicycle if there are better options. You can also try and lock your bicycle where there is CCTV for extra protection. 

How do I carry my locking system with me when cycling?

This all depends on the kind of bicycle locking system you have. Some D/U locks can be attached to your bicycle via a bracket. You could also try and screw it to your seat tube where your upright bottle would have been. 

Wherever you decide to attach your lock you should make sure it stays a distance from your brakes and tyres to avoid any accidents happening when cycling. 

For chain and cable locks you may have to store these on a pannier rack or in a backpack if you have one.
