Locks test 2012


Fully updated and including 11 newcomers, Rowan Lamont, assisted by the officers of the Brisbane City bike police, tested a selection of 27 locks to see how well they protect your precious property. 

For this year’s instalment of our popular bike lock test, Ride On collected a range of the most interesting new and current locks to determine the best and best value at high, medium and low security levels. Thinking like thieves, we tested the locks to breaking point using techniques that were quick, simple and least likely to draw attention to ourselves. If a lock showed resistance, we increased the severity of the tools and techniques we used.

D-locks continue to offer the highest security. Even the cheapest require an angle grinder to break – a hacksaw can’t get through hardened steel.

A surprise in this test were the hardened steel chains combined with resilient locks. These proved very awkward to break into, providing a great deterrent along with the convenience of being easier to stow than many D-locks.

The lowest level of deterrent came from light and small cables, which require very little ingenuity to break. They can be used to add an additional deterrent along with a bigger lock, or if you just need something to prevent someone walking off with your bicycle while you pop into a shop, but not much more.

The main thing to consider when choosing a lock is the security it offers. If you leave your bike in high-risk situations then you will need a lock that offers high security. A medium security lock would be sufficient if you never leave your bike in a high-risk situation, with the advantage that a medium security lock is generally lighter and less expensive. Another thing to consider is the size of the lock. You might prefer to carry a more compact, smaller lock or you might require a longer, flexible lock such as a chain or a cable to effectively secure your particular bike, such as a cargo bike or trailer. Supplementary cables, such as the Kryptonite Kryptoflex reviewed here, are very useful for locking the wheels as well as the frame or for securing unconventional bikes, trailers, tag-alongs and the like.

The locks are rated on a scale that takes into account function, materials and components, construction, appearance and value for money – within a broader designation of the security level offered. For all locks, it’s important to consider the intended usage and level of security required.

Key to security

Sergeant Michael Schodel knows from personal experience how attached you can get to a bicycle. “I can remember the smell of the bike shop I bought my very first bike from as a kid,” he told Ride On. As a bike mounted officer from Brisbane City Police Station he’s in his dream job and he’s learned a lot about how bikes get stolen.

He and his partner Constable Alana Johnson have three key messages about bike security:

1. Smart positioning

Select a well-lit public place where there are lots of people around. It is even better if there is CCTV coverage.

2. Solid anchoring

Lock your bicycle to as strong and solid an object as you can find as many thefts don’t even have the lock broken. When bicycles are locked against a wall or to flimsy railings they are an easy target for an opportunist thief.

3. Effective recording

The Brisbane police donate many bicycles to community organisations each year that once belonged to a bicycle rider but can’t be returned. A simple solution is to record the serial number of the frame, which is usually underneath the bottom bracket. If you lose your bike, report it and quote its serial number.

Thefts can also be deterred by taking some simple steps to add complexity to the security you use, creating extra inconvenience for a would-be thief. Take advantage of bike cages, use a couple of locks – one for your frame and another for the wheels – and lock the front wheel to the frame. If you regularly leave your bike in the same place each day, you expose it to a possible planned theft. Instead, park in a few different locations to help reduce this risk.

High security – D-locks, chains and a folder

The hardened steel and robust lock mechanisms of these locks means they offer high security, yielding only to an angle grinder. The Abus Bordo 6000 folding lock is included here because it gives such a high degree of protection that it offers an alternative to a D-lock. Chains also offer high security because they are very awkward to attack and require an angle grinder to be broken.

Medium and low security – cable locks

Cables are light weight and convenient, but offer low security. Some of the thicker and more expensive cable locks are more time consuming to break, but all these cables can be cut through with bolt cutters. Some of these locks can be broken by just smashing the lock mechanism apart with a hammer. For a high security lock, see the previous section.

One thought on “31”

    1. Hi Nicholas. Sorry we don’t test all the locks on the market. That’s not a particularly common one except on European brand bikes. The fact that Gazelle fit it to their bikes is a good recommendation. Thanks for the feedback.

  1. what about the bunnings masterlocks?
    (the ones that are impulse buys at the checkout)

    i know they are useless, but for $8, id be really curious to see how they compare to the higher priced options.

    of course, the other option is to have a bike that no one wants to steal…

  2. Hey you forgot the Kryptonite New York (Fahgettaboudit) It carries some weight but has served my well. I keep it stored at my regular destination to save on carrying it. Would have to take top honours. Would like to see it tested.

    1. Kryptonite New York: pretty much mentioned as the top Lock everywhere so a surprising omission, in fact glaring omission. Nevertheless, a very nice list and very useful, so thanks.

  3. A common way of stealing bikes using D locks around Texas is by using a long board (2×4) twist and pry locks off. This is generally faster and doesn’t require cutting. I’d be curious which of these locks withstand leverage from a board.

    1. In the 2011 test we tried leverage, but not quite how you seem to describe. We found this was tricky to do without causing significant, ugly damage to the bike. Based on what you say though we’ll investigate leverage again next test. Thanks for the information.

      1. A few years ago in London before the smaller dlock sizes became popular it was common for people to steal bikes using a mini car jack as they typically lift about 1 ton for a car or explode a dlock outwards. Obviously selecting the correct size dlock won’t leave you open to this but sometimes people have larger ones and a few inches gap.

        Good reviews, I’m in the process of selecting some new locks and cutting is my only real worry. In work I leave my bike near a smoking area so at most 20min between someone standing a few feet away.

  4. I can imagine a thief using an angle grinder would be not all that conspicuous… Still though, some are pretty brazen. I’m with Dave though, I don’t think I’d be leaving my $5000 bike in a city bike rack even with a D-lock on it.

  5. Also be aware of thieves simply unbolting the ENTIRE bike rack from the footpath and lifting it and all the bikes on it into the back of a van/ute.

    Sometimes they may even visit the rack at night to loosen/chop the bolts to make their job easier down the track.

    And of course be aware that locking to poles can see your bike lifted up and over, especially if the ‘No Standing’ sign/bracket at the top can simply be unbolted off.

    They are lowlifes, but they can be cunning.

    Battery angle grinders are our enemy.

  6. Please let me know when you plan to test for 2013. Commando Lock would like to submit a sample for destruction. We’re not yet known in the bike market but the US military favors our products at top quality. Patrick Smith

  7. Pit locks are great too http://www.pitlock.com/ – i have a touring bike with schmidt dynamo hub on the front & rohloff hub at the rear. and also use the Abus Granit lock – it’s heavy, but would prefer that than no bike

  8. I purchased the Ortre BI5 lock based on its good results in this test. It’s a stylish lock to be sure, but it does not require two cuts to open as stated in this test.

    It could easily be opened with one cut, it just depends which side you cut. Only one end of the U locks into the base, so if you cut the side that does not lock, sure it would still be held in by the side that does, and require another cut. But if you cut the locked side, the whole U would just slip out easily.

    I feel a bit misled by this test, and will now be looking at buying another, more secure lock.

  9. A trick used years ago by theives was to use THEIR OWN lock to secure YOUR bike which enabled them to come back later and get the bike – it happened to me once: I called my father, but he couldn’t cut it with his selection of tools, so he went down the road to the fire brigade who didn’t have anything to do so came over and cut off the would be thief’s lock! Ha! Take that!

    When I strolled into the college canteen the next day, the ‘thief’ stood up and shouted at me: ‘you tosser! you wrecked my lock” it was a mate playing a practical joke on me. 🙂

  10. Another common trick which D-Locks are especially prone to is the use of some kind of freezing agent (eg the cans of compressed air you can get to clean computer keyboards, etc… then turn the can upside down to fire the cold propellant at the lock) to freeze the locks, then one sharp tap with a hammer shatters even the toughest lock. Worth trying this in the next test (eg layers of silicone may protect it from freezing).

  11. Hi,
    Just figured you may want to update your review, as I’ve just purchased an Ortre BI5 and upon inspection, it’s quite clear that the lock will only have to be cut once, as only one of the C-prongs are actually locked inside the end-piece.

    There’s also a small amount of play between the C and end-piece once locked.

    Other than that, it is nice, light and compact.
