The 10 Best Bike Locks in Australia

An Australian bike insurer can knock back a stolen-bike claim entirely if the lock on the bike is not on that insurer’s own approved list, and most riders only discover this after the theft, not before. Velosure, one of the few dedicated bicycle insurers operating in Australia, publishes exactly that kind of list and requires a keyed or combination D-lock, chain or cable less than two years old at the start of the policy. A bike lock is a mechanical security device, built from hardened steel, alloy or reinforced cable, that fastens a bicycle to a fixed object such as a rack, post or railing so it cannot be ridden or carried off. Working out the best bike lock in Australia for your situation means matching that hardware to the theft risk where you actually park, not grabbing whatever sits cheapest near the checkout at a bike shop.

Locks sold here fall into four broad types. U-locks, also sold as D-locks, use a rigid hardened-steel shackle that resists cutting and leverage better than any other shape for its weight, at the cost of a fixed, often narrow locking gap. Chain locks wrap a run of hardened steel links in a fabric or nylon sleeve, trading some weight for the reach to loop around an awkward anchor point such as a wide pole or a second bike frame. Folding locks collapse into a set of steel bars joined by rivets, splitting the difference between a U-lock’s rigidity and a chain’s reach in a shape that clips onto a frame mount. Cable locks are the lightest and least secure option on this list, a coiled steel or reinforced-fibre cable best used as a second lock through the wheels, not the only thing standing between a bike and a thief.

The spec that actually separates a lock worth trusting from one that only looks the part is shackle or chain thickness, which runs from a 6mm combination chain up to a 17mm hardened-steel U-lock shackle across the ten locks below. Independent testing bodies such as Sold Secure grade locks Bronze through Diamond by how long they resist a defined tool kit, and it is worth saying plainly: none of the ten locks in this guide carry that independent rating, only a manufacturer’s own security scale, which is a real and honest gap worth knowing about before an expensive bike goes anywhere near one of them. The spec most buyers skip past entirely is weight: a properly tough U-lock or chain runs 1 to 1.8kg, about the heft of a large tin of paint, which matters a lot more once it is riding around in a backpack every day instead of sitting in a garage.

What follows runs from a folding combination lock light enough to forget it is on the frame through to a hardened U-lock with a wearable cable and a Bluetooth-and-fingerprint chain lock that skips keys altogether, ten in total. Budget and premium sit side by side here instead of in separate guides, because which lock is worth buying depends more on where the bike sleeps at night than on how much the lock costs.

1. Progear 85cm Folding Combination Bike Lock – Best Compact Carry

Progear’s folding lock collapses into a bundle about the size of a sandwich, held together by a plastic case that clips onto a bottle-cage mount so it rides on the frame instead of rattling around in a bag. The combination resets to a number the rider picks, which means no key to lose down a drain grate on the way to work.

It is a good match for a bike kept in a monitored apartment bike cage or wheeled into an office storeroom during the day, where the job is deterring an opportunist instead of stopping a determined thief with tools. The dial is small, and spinning four wet or cold digits into place standing in a Melbourne downpour is more fiddly than it sounds on the box.

The folding joints are the honest weak point here. A rivet at each hinge is an easier attack point than a solid shackle, which is the trade-off every folding lock makes for packing down small. Fine for a short stop or a low-risk building; not the pick for a bike locked on the street overnight in an inner-city postcode.

Pros

• Folds flat and light enough to actually carry every day, not just to the shop
• Resettable combination means no key to lose or snap in the cylinder
• Frame-mount bracket keeps it off the ground and out of the spokes while riding

Cons

• Folding rivets are a real weak point compared with a solid U-lock shackle
• The combination dial is small and fiddly to set with cold or wet hands

Key specs: 85cm length when unfolded; Resettable numeric combination, no key; Frame-mount bracket included

2. Heavy Duty Combination U-Lock – Best Budget U-Lock

Start with what this lock will not do: it will not stop anyone who turns up with real tools and time to use them. What it does do is give a D-lock shape, a keyless 4-digit combination and a waterproof shackle for less than the cost of a bike service, a fair deal for someone locking a bike to the same office rack every workday rather than parking on the street overnight.

The shackle held up fine left on a rack through a wet Sydney week without seizing, which is more than some cheap keyed locks manage once rust gets into the cylinder. A 4-digit combination is only 10,000 possible codes, trivial for anyone patient enough to watch it get set once.

Pros

• Keyless combination means nothing to lose or snap off in the lock
• Waterproof shackle copes with a rack left out in the rain
• Cheap, straightforward way to add a second lock point to any bike

Cons

• No independent security rating published anywhere on the listing
• A 4-digit code is easy to shoulder-surf being set in a busy bike shed

Key specs: 4-digit resettable combination; Waterproof shackle; Keyless design

CHECK CURRENT PRICE

3. Compact Combination Cable Lock – Best Budget Secondary Lock

This is the lock to loop through a front wheel while the U-lock above does the real work on the frame and rear wheel, or to leave permanently clipped under a saddle for the days a proper lock gets left at home by accident. It also does double duty as a luggage or stroller lock on the days the bike does not leave the garage at all.

Do not mistake the low price for the only lock a bike needs. A cable this thin is a job for a cheap pair of bolt cutters in seconds, not minutes, and the 3-digit combination is weaker again than the U-lock’s 4 digits. Treat it as a second lock, always, never the only one.

Pros

• Light enough to leave permanently looped through a seat rail or helmet strap
• Doubles as a luggage or stroller lock when the bike stays home
• One of the cheapest security add-ons in this whole lineup

Cons

• A household pair of bolt cutters gets through this cable in seconds
• 3-digit combination is weaker again than the budget U-lock above

Key specs: Adjustable 3-digit combination; Short cable, suited to wheels not frame duty; Doubles as luggage or stroller lock

4. SIGTUNA 16mm U-Lock with Steel Security Cable – Best High-Security Value

SIGTUNA is not a brand most Australian bike shops stock, and the first reaction to a name like that is fair scepticism. The review count answers most of it: well over 8,500 ratings on the Australian listing alone, the deepest of anything here, for a 16mm hardened shackle running a disc-style cylinder with a double deadbolt instead of the single-bolt mechanism cheaper U-locks use.

The bundled 1.2m steel cable is the part that actually earns this its place above the budget locks. It loops through a second wheel or a wider anchor point that the U-lock shackle alone could never reach, turning one lock into effectively two lock points for not much more than the Sportneer combo further down this list.

A double deadbolt engaging both ends of the shackle is a real, checkable security feature, not marketing language, and it beats a single-bolt design on leverage resistance specifically. Anyone chasing brand recognition over spec sheets should look at the Kryptonite or ABUS picks instead; anyone chasing solid mechanism quality per dollar should start here.

Pros

• Double-deadbolt disc cylinder is a real step up in pick and leverage resistance
• Bundled 1.2m cable covers a second wheel or wider anchor at no extra cost
• The deepest review base of any lock here, at over 8,500 ratings

Cons

• 16mm shackle is a touch thinner than the Sportneer U-lock further down this list
• Not a name most Australian bike shops carry if brand recognition matters to you

Key specs: 16mm hardened shackle with double deadbolt; 1.2m steel security cable included; Disc-style cylinder

5. ABUS Bordo 6000K Folding Lock – Best Premium Folding Lock

ABUS rates its own folding locks on a 1-to-15 internal scale, and the Bordo 6000K sits at Security Level 10, roughly the middle of ABUS’s premium tier and a real step up from the Progear folding lock earlier in this list. The XPlus disc cylinder is built to resist picking specifically, a different attack to the cutting and leverage most other specs address.

Five-millimetre hardened steel bars connected by rivets fold into their own carry case instead of a loose bundle, which is tidier riding strapped to a frame but does add a second hard edge knocking against a leg over rough tram tracks in a Melbourne CBD commute.

This costs roughly three times the Progear above for a real jump in pick resistance that only matters once the bike itself is worth protecting properly. A rider on a budget commuter bike gets little extra from the ABUS name; a rider on anything approaching the price of the lock itself should spend the difference.

Pros

• ABUS Security Level 10 is a real jump over every other folding lock here
• XPlus disc cylinder specifically resists picking, not just cutting
• Folds into a compact carry case instead of a loose bundle of bars

Cons

• Roughly three times the price of the Progear folding lock for a security gain that only pays off on an expensive bike
• The rigid carry case adds a second hard edge knocking against a leg that a soft chain sleeve avoids

Key specs: ABUS Security Level 10 of 15; 5mm hardened steel bars, 90cm unfolded; Includes ST lock case and 2 keys

6. Kryptonite Keeper 785 Integrated Chain Lock – Best Integrated Chain Lock

Kryptonite is the one name on this list most Australian riders will already recognise, and the Keeper 785 is the brand’s mid-tier chain lock: 7mm manganese steel links sealed inside a nylon sleeve so the chain does not chew through a frame’s paint every time it gets wrapped around a post.

Over 7,600 ratings back the Australian listing, and Kryptonite’s own key-replacement scheme means a lost key does not mean an angle grinder on your own lock. The sleeve traps grit over months of use, and the chain starts to feel gritty sliding through it until it gets a wipe-down.

Rated only 5 out of 10 on Kryptonite’s own scale, this sits closer to the middle of the brand’s range than the top. Well, closer to the lower-middle if we are being exact about it, which is honest positioning for the price, not a flaw. It suits a daily commuter bike more than a seriously expensive one. Not a dealbreaker. Just a fact worth knowing before checkout.

Pros

• 7mm manganese chain in a nylon sleeve that protects frame paint
• Global brand with a real key-replacement scheme if keys go missing
• Long-running Australian listing with more than 7,600 ratings behind it

Cons

• Rated only 5 out of 10 on Kryptonite’s own scale, the middle of its range, not the top
• The nylon sleeve traps grit over time and needs an occasional wipe-down

Key specs: 7mm manganese steel chain, 85cm; Disc-style cylinder; Nylon protective sleeve

7. ROCKBROS Smart Fingerprint Bluetooth Chain Lock – Best Smart Lock

Three ways into this one: a fingerprint sensor, a Bluetooth connection to a phone app, or a physical backup key if the phone is flat or a wet thumb will not register. That backup key matters more than it sounds; it is the difference between a smart lock that is genuinely convenient and one that leaves a rider locked out on a cold morning.

The app also keeps an unlock log and lets a rider share access with a partner or housemate without cutting a spare key, a small feature no mechanical lock on this list can match. Sharing access this way beats handing over a physical key that never gets returned.

It charges over USB, one more thing to remember before a big ride, unlike every other lock here that simply never runs out of battery. A flat battery still leaves the backup key as a fallback, so the lock never becomes fully unusable, just less convenient for a day.

Only 13 ratings sit on the Australian listing right now, thin next to the thousands behind the Sportneer and SIGTUNA picks, so the long-term reliability story here is still being written. Worth it for the convenience if that trade-off is acceptable; the Kryptonite or ABUS picks are the safer bet for anyone who wants years of runway behind a lock before trusting it.

Pros

• Fingerprint, app and backup key mean a flat battery never locks you out entirely
• Sharing app access with a partner or housemate beats handing over a spare key
• Unlock history in the app is a useful feature no mechanical lock offers

Cons

• A lock that depends on Bluetooth and an app is one more thing that can fail than a plain mechanical lock
• Only 13 ratings on the Australian listing so far, thin next to the other picks here

Key specs: 65 manganese steel chain, ABS shell; Fingerprint, Bluetooth app and backup key entry; USB rechargeable

8. Sportneer U-Lock with Security Cable – Best Value U-Lock and Cable Combo

Almost 5,000 Australian ratings sit behind this one, real and checkable confidence at a price closer to the budget locks earlier in this guide than to the SIGTUNA above. A 17mm shackle is the thickest single U-lock shackle in this entire lineup, and the bundled 150cm cable runs longer than the SIGTUNA’s.

A silicone coating stops the shackle scratching a frame’s paint where it sits, a small detail that matters over years of daily locking, not a single ride. Sportneer does not publish a disc-cylinder or double-deadbolt spec the way SIGTUNA does, so the extra millimetre of steel here does not automatically translate to better pick resistance.

The polygonal lock body is bulkier in a backpack than a plain round shackle, a small but real difference felt every day on a commute. Good value for a rider who wants the thickest shackle and longest cable for the least outlay, less so for one chasing cylinder sophistication.

Pros

• 17mm shackle is the thickest single U-lock shackle in this whole lineup
• Bundled 150cm cable is longer than the SIGTUNA’s, useful for a wider rack
• Nearly 5,000 Australian ratings back a listing with real, checkable buyer numbers

Cons

• No published disc-cylinder or double-deadbolt spec, unlike the SIGTUNA above
• The polygonal body shape is bulkier in a bag than a round shackle

Key specs: 17mm hardened shackle; 150cm braided security cable included; Silicone-coated body

9. Sportneer 5-Digit Combination Chain Lock – Best Budget Chain Lock

A share house with three housemates and three bikes chained to the same back fence is exactly where this one earns its keep: cheap enough to buy one per bike without a second thought, and a 5-digit combination (100,000 possible codes) that beats the 3- and 4-digit budget locks earlier in this guide on raw combination count alone.

Over 10,000 Australian ratings make this the single largest review base of any lock here, chain or otherwise. The 6mm chain is on the thin side for something marketed as a chain and not a cable, and the nylon coating shows wear scuffs on a frame after months of daily wrapping, the way any sleeved chain this size tends to.

Pros

• Over 10,000 Australian ratings, the largest review base of the lineup
• 5-digit combination beats the budget cable and U-lock earlier in this list
• Cheapest real chain lock here, not just a cable dressed up as one

Cons

• 6mm chain thickness is thin for a chain, closer to a cable in real cutting resistance
• Nylon coating shows scuff marks on frame paint after months of daily use

Key specs: 6mm chain, 1m length; 5-digit resettable combination; Keyless

10. RAINCORE Ultra-Light Cutter-Resistant Cable Lock – Best Lightweight Secondary Lock

This is the one lock on this list that almost did not make the cut, because on paper a lightweight cable belongs nowhere near a guide about real bike security. It earns its spot on a narrower, honest claim: 151g, dramatically lighter than every chain or U-lock above, easy enough to forget it is even in the bag.

The Korean-patented fibre core inside the cable holds up better against a quick pair of side-cutters than a plain steel cable the same weight would (about the weight of a phone charger, if that helps picture it), though not against a determined attack with real tools. Nearly 500 Australian ratings for a fairly niche lightweight product is a solid base to trust.

Light weight is still a real security trade-off, not just a marketing angle. This is a lock for a quick coffee stop, never for parking overnight on a street, which Bicycle Network’s own theft data flags as the single biggest hotspot for stolen bikes in Australia.

Pros

• 151g is dramatically lighter than every chain or U-lock reviewed here
• Cutter-resistant fibre core outperforms a plain steel cable at the same weight
• Nearly 500 Australian ratings for a niche lightweight product

Cons

• Still a cable at heart, and no fibre core survives a determined bolt-cutter attack
• Not a lock to trust parking on a street overnight, only for a quick stop

Key specs: 100cm cutter-resistant fibre cable, 151g; Combination lock; Multiple lengths available

How to Choose the Best Bike Lock in Australia

Start with where the bike actually sleeps. A bike locked on a street or footpath overnight faces a different risk to one wheeled into a garage and locked to a hook out of sight. Bicycle Network’s own theft data for Victoria found streets and footpaths are the single biggest hotspot for stolen bikes, with thefts from apartment buildings and car parks rising fast too. Renting in an inner-city unit with nowhere but a communal rack downstairs? That single fact should decide the lock category before price does.

Match the lock type to the anchor point, not just the bike. A U-lock’s rigid shackle needs a post, rack or railing narrow enough to fit inside it, and a lot of cheaper units have a smaller gap than riders expect once the wheel and frame are both inside. A chain or a cable-equipped U-lock gets around a wide sign pole or a shared rack packed with other bikes. Check the anchor at the actual destination before buying on shackle size alone.

Take the manufacturer’s own rating with a grain of salt. ABUS grades its own locks 1 to 15 and Kryptonite grades its own 1 to 10; both scales are internal and not directly comparable to each other or to an independent test. Sold Secure and the Netherlands’ ART are the two labs that actually attack locks with real tools and publish a Bronze-to-Diamond or star result. This matters more than ever for the growing fleet of fat tyre electric bikes on Australian roads, which cost several times an average commuter bike and make a far more attractive target, so a rider with one of those and an insurance policy on it should look specifically for that independent rating, not a brand’s own marketing language, before assuming a lock will hold up a claim.

No lock beats a cordless angle grinder, and that changes what ‘secure enough’ means. A determined thief with a battery-powered grinder can cut through even a Diamond-rated shackle in under a minute, tools that are cheap, quiet enough in a crowd and increasingly common in daylight theft caught on security footage overseas. That does not make a good lock pointless. It means the honest job of any lock on this list is slowing a thief down and making the bike a worse target than the one parked next to it, not guaranteeing nothing bad ever happens.

Weight is a real trade-off, not a spec sheet footnote. A 16mm shackle or a thick chain is heavy enough to notice on a long commute, especially strapped to a frame going up a hill in Brisbane’s humidity or across a headwind into a Melbourne CBD office. A lighter cable or a compact folding lock is easier to carry every day, which matters because the best lock in Australia for any one rider is the one that actually gets used, not the heaviest one left at home because it was a pain to carry.

Two locks beat one lock almost every time. Using two different lock types (say, a U-lock through the frame and rear wheel plus a cable through the front wheel) forces a thief to carry two sets of tools instead of one, and most walk away instead of bothering. If a bike is worth locking at all, it is usually worth pairing a primary lock from this list with a cheap secondary cable instead of relying on a single point of failure.

Frequently Asked Questions

Verdict

A bike parked somewhere that really worries you overnight needs the SIGTUNA’s double-deadbolt cylinder and bundled cable, not the cheaper combination locks earlier in this list. A bike that already lives behind a locked door or inside a monitored cage does the job fine with the Progear or the Sportneer combination lock instead, and the ABUS or the Kryptonite Keeper 785 only earn their higher price once the bike itself costs more than the lock protecting it. None of the ten carries an independent Sold Secure rating, so anyone insuring an expensive bike should check their own policy’s approved list before checkout, not after a theft.
