Uncuttable Bike Locks [3 Locks That Can’t Be Cut]
When searching for a bike lock, it can be hard to know where to start with regards to key features that you should consider, and what level of security protection you need.
Arguably the most important aspect you should consider (as well as be aware) of is how easy the lock is for thieves to cut through while your bike is locked up. The easier it is, the less protection it offers.
Is There a Bike Lock That Can’t Be Cut?
There are bike locks on the market that do claim to be uncuttable. However, the vast majority can still be cut through, but will take some serious effort as well as time. A lot will also need special heavy duty tool to successfully cut.
But that’s not actually bad news. Having a lock that takes time and effort to get through is still worth having, as the more hassle a lock is to break or cut through, the less likely a thief is to attempt to get through.
Equally, if you want a lock as a deterrent, knowing that most locks will eventually be cut through, then you could also consider bike locks with alarms. This way, you’re notified if someone is stealing your bike, and the alarm itself puts potential thieves off.
Which Bike Lock is Hardest to Cut?
The hardest bike locks to cut through are often those that are labelled as sold secure ‘diamond’ standard. However, D locks do tend to be a consistently solid option if you’re looking for a bike lock that is more difficult to cut.
In addition, any bike locks that have been made out of steel are also a strong option (literally!) as they too are harder for thieves to cut through. This is another important feature to look out for when selecting a bike lock.
Similarly, bike locks that are heavier, as well as thicker in design, will also take a lot longer for a potential thief to get through in order to steal your bike. Although annoying and not very practical to carry around on you, the heavier the lock, the more effective it is at keeping your bicycle safe.
Bike Lock That Cannot Be Cut with Angle Grinder
As amazing as they would be, locks that cannot be cut with an angle grinder are unfortunately pretty hard to come by, which is infuriating given a lot of bike thieves will now steal bikes using such tools.
Because of the nature of an angle grinder, any lock that claims to be angle grinder proof would have to be a pretty heavy duty lock itself to withstand such force. This weight could make the lock difficult to carry around with you for everyday use.
It’s important to note that such locks may also cost a fair amount more in comparison to less effective locks. This is because of the amount of materials and technology needed to produce a lock so strong wouldn’t come cheap.
