3 (Almost) Uncuttable Bike Locks

First and foremost, it’s hard to not notice the sheer size of this lock This thing is an absolute beast. There’s no looking past the fact that it’s most likely the biggest and thickest bike lock on the market. However, regarding uncuttable locks, this is brilliant.

Coming in at a whopping 6.2kg this heavy duty lock claims to be totally resistant to attacks by thieves welding angle grinders. Pretty impressive right? Therefore, the weight is definitely out weighed by the benefits of having such a solid and hard to cut through lock. Especially if you are leaving your bike for a prolonged time in a public area.

Although heavy and made from steel and aluminium, it does actually have a softer coating on the outside in order to protect your bike and not scratch it. This, of course, does not add to the safety of your bike from thieves, but it’s good to know that for everyday use, your beloved bike won’t become scratched.

Boasting to be the ‘best and most secure lock in the world’, and angle grinder proof, this lock would suit those wanting full protection and peace of mind while leaving their bike locked up in the street (or a shared area) for a prolonged period.

The Core Plus from LITELOK was the winner of the Reddot Design Award in 2021, and has also been awarded a sold secure diamond rating for bicycle security. Not to mention that unlike the previous offering, it’s also super lightweight – coming in at an impressive 1.9kg for the smaller size.

In addition to being nice and light, this particular model also comes in a choice of two sizes: either 75cm or 100cm. You can select a size that suits you and your needs which is not often an option offered for a lock: it’s usually a one size fits all job for most models.

Instead of transporting this lock around in your bag or on your bike like many other locks, this one can also be worn around your waist (as well as attached to your bike) to make for a more convenient ride. Of course, ensuring you buy the right size to fit your body is essential.

All round, this lock is a solid option for those wanting practicality and safety. It will be hard to cut through thanks to its Boaflexicore Plus secure strap, which can withstand sustained attacks.

Last but not least, we turn to the German company ABUS who are well known for their sturdy and reliable locks. The Granit Extreme is no exception: it’s a solid all round option for those wanting a reliable lock thanks to its hardened steeled design (which will make cutting through difficult), but maybe not needing something as robust as the previous options.

Regarding the weight, this lock is a pretty reasonable 2.70kg. Therefore either mounting it to your bicycle or throwing it into your bag will be pretty straightforward and hassle free. Although it isn’t as light as some other locks on the market, it’s still pretty decent.

Likewise, this lock also features the ABUS XPlus cylinder which offers exceptionally high protection against any attempts of tampering, such as picking the locks. Therefore this lock would be a good option for those not needing as much protection as the other two locks, but still wanting a good level of security.
