Best bike locks in Australia

The OnGuard Brute STD U-Lock is the perfect lock for most folks. It’s durable enough to be used in most areas, regardless of their crime level. It’s made from 16mm of hardened alloy steel, to protect against the force of power tools. It weighs 1.6kg, which is roughly the same as our runner-up.

As an added precaution, the bar locks at both ends. This means that anyone looking to cut through your lock will need to take the time to do so on both sides. It’s budget-friendly at sub-$120, yet still delivers comparable quality and security to its high-end competitors. It also comes with five replaceable keys, including an LED one for when you ride home in the dark.

The Kryptonite Keeper 790 is a chain lock renowned for its high-impact strength. This bad boy is made from 7mm of hardened manganese steel wrapped in a nylon sleeve. To cut through to the steel, any bandits with power tools will need to grip the slippery sleeve while cutting – an obstacle that's easier said than done.

Even though it’s heavy-duty, the Kryptonite Keeper 790 isn’t as heavy as you’d expect. It comes in at 1.7 kg, which is surprising given the high-quality materials it uses.  It’s not the highest security lock on the market, but it’s an affordable choice made from quality material. It’s ideal for folks in medium to low-risk areas who want extra peace of mind while they’re out grabbing groceries or riding to and from school.

The Via Velo Heavy Duty U-Lock is a cost-effective, fuss-free lock that does what it says on the tin. It’s also weatherproof, so you won’t have to worry about a bike lock that freezes in icy temperatures. It’s also encased in a hexagonal PVC cover to protect it from water, dust, and dirt. While it won’t keep your bike safe from nature’s wrath, it’ll extend the life of your lock. 

We love the pull-resistant lock cylinder and double-bolt crossbar lock. Even though it’s a budget lock, it still aims to protect against tampering, prying, and drilling. It also uses 15mm of thick, hardened steel encased in rubber so you can rest assured your bike will remain safe when left unattended. 

In the box, you’ll also find a flexible 1.2m long woven steel cable that can be used to secure larger bike frames, two replaceable keys and a mounting bracket.

The Litelok X3 is a feat in bike locks for those who have cash to spend. It's made of Barronium, a composite material created by Litelok to actively prevent angle grinder attacks. Without adding extra weight, the material provides protection and resistance against common tools. The most interesting part of this lock is that the barronium turns the grinder’s force in on itself. The more force applied, the more it’ll damage the angle grinder.

Not only does it protect against the attacks of drills or power tools, it actively damages those tools in the process. Eye-watering cost aside, this lock is all but guaranteed to make your bike hard to snatch. 

The lock is also encased in a plant-based eco-rubber, so it won’t scratch off the paint on your bike frame. Even though it is a tad heavy, we reckon it's a solid tradeoff for the security it offers.

The ABUS Steel-O-Chain 8807 is a chain lock renowned for its flexibility. You’ve got two options for length (85cm or 110cm), so you can choose what works best for you. The 7mm thick chain is made of hardened steel, to protect you from potential thieves. This bad boy can connect to any object regardless of its size and works best to protect your bike in medium to low-risk areas. It’s affordable, yet still offers solid protection for when you want that extra peace of mind.
