The best bike locks might not be the cheapest bike accessory you're going to buy this year, but they are essential to ensure your bicycle stays where you chained it. A tough, dependable bike lock will is a worthwhile investment; if you can stretch to buying a new two-wheeler, then it’s also prudent to factor in some extra cash to cover security, and buying the right bike lock to suit your cycle should be part of the bike-buying process.

There's been a huge increase in cycling over the last few years and the extra demand for bikes that are much more appealing to thieves. The best electric bikes, in particular, are at risk of being nicked if not secured properly, and while some have an immobilizer that stops them from being activated and ridden away without you present, that won't stop someone picking them up and stashing them in a van.

All that means it’s never been more important to get a quality bike lock to ensure your cycle doesn't go missing, and we’ve collated the best and most secure bike locks you can buy here in this buying guide. We’ve tried to mix it up a little, too, with a selection that caters for different scenarios, while others offer a little more convenience thanks to their innovative designs.

Litelock X1 bike lock attached to a bike

The best d-lock for bikes we've reviewed so far

Specifications

Type: Steel D-lock
Weight: 3.71 lbs (1.7kgs)
Security rating: ART4 accredited

Reasons to buy

+
Reinforced against angle grinders
+
Rubberized to prevent frost
+
Twist-and-go bike mount 

Reasons to avoid

-
A little tight for some frames
-
Premium price

The Litelock X1 is a premium-priced, premium-feeling D-Lock, dependable with a practical edge. The key entry point is covered by the rubber coating, preventing it from seizing up in the cold, while the steel d-lock is said to be reinforced against angle grinders thanks to its 'barronium’ composite metal layer.

During our tests, we loved the d-lock, finding it well-engineered, with a convenient twist-and-go bike mount, and it's practical too. No fuss, no frills, simply a premium-feeling, premium-performance lock you can depend on.

Our one gripe was its tight spacing issue: if you want plenty of room and don't like the idea of your bike's frame getting slightly scratched, this is a smallish lock, so you may want something with a bit more give. However, small locks are that much more awkward to break. It also comes with two keys, so you're covered if you lose one.

Kryptonite Kryptolok 685 folding lock

The best extending lock

Specifications

Type: Extending lock
Weight: 2.86 lbs (1.3 kgs)
Security rating: Kryptonite 6 (moderate)

Reasons to buy

+
Heavy duty barrel lock
+
85cm reach
+
Mounting bracket included

Reasons to avoid

-
Only 'moderate' rating

This Kryptonite offering is one of the best extendable locks, which are bars of metal secured together by hinges. The concertina lock reaches up to 85cm when fully extended, allowing you to loop through wheels and frame, and collapses into a single rod when not in use. 

It can take a variety of shapes so can help to lock around unconventional shapes and thick lampposts, its barrel lock is excellent in terms of build quality, and the included bracket offers easy mounting. However, like all extendable locks of this type, the hinges are natural weak points in the design, and probably wouldn't stand up to a concerted effort with an angle grinder for very long. 

Its a good lock and one of the best of the extendable lock family, reasonably priced and comprised of hardened steel - an excellent deterrant, even if it won't stand up to dedicated or professional thieves.

3. Kryptonite Evolution Mini-7

A solid U-lock and cable combo makes life hard for thieves

Specifications

Type: Hardened steel D-lock
Weight: 3.55 lbs (1.61 kgs)
Security rating: Sold Secure Gold

Reasons to buy

+
Good build quality
+
Combo design is neat
+
LED key fob

Reasons to avoid

-
Not a long-term lock solution
-
More stuff to carry

It makes sense to go for a decent bike lock brand, and Kryptonite is up there with the best of them. This great little bundle comprises a 13mm hardened steel shackle, which features a double deadbolt anti-rotation design. The U-lock design doesn't weigh too much either (3.55lb/1.61kg), while the revised design is more secure than earlier editions.

The Mini-7 is much smaller than Kryptonite's standard locks, which makes it easier to mount on your bike's frame if space is limited (and gives a would-be thief much less room to manoeuvre their tools). The mount attaches to the frame securely using a rugged fabric strap that won't damage the paintwork, and the lock slides and clips into place with minimal fuss.

The Evolution Mini-7 comes complete with a Kryptoflex 410, a 4' 10" double-loop braided steel cable. This can be used to secure other bikes, wheels or accessories, which is essential since the Mini-7 U-lock is too small to attach to your bike's frame and a wheel. While it's not impregnable, the fiddly aspect of this combination makes the lock package a solid option for short-stay park-ups in cities and suburbs.

In our tests, we found that the lock can sometimes rattle a little within its holder when riding over bumpy ground, but it's firmly fixed in place and never in danger of coming loose, so this is a minor complaint.

4. Kryptonite New York Fahgettaboudit Mini

A chunky, simple but effective bike lock

Specifications

Type: Hardened steel D-lock
Weight: 4.55 lbs (2.06 kgs)
Security rating: Sold Secure Gold

Reasons to buy

+
Excellent durable design
+
Set of quality stainless keys
+
Anti-theft guarantee

Reasons to avoid

-
Smaller design might not suit all bikes
-
Quite heavy due to its construction

Another bike lock from the Kryptonite security stable, the New York Fahgettaboudit Mini, is sold without a cable but beefs up the security with an extra chunky design. It's seriously weighty (4.55lbs/2.06kg), which is something to bear in mind if you cannot mount it on your bike and carry it in a backpack, but that heft comes with security benefits.

The main difference between the Kryptonite New York Fahgettaboudit Mini and the Evolution Mini-7 is the oversized hardened steel sleeve, which is built to withstand attack from bolt cutters and leverage attacks. It makes the Fahgettaboudit Mini a lock that will keep your bike secure all day, even in busy cities.

Like the Kryptonite Evolution Mini-7, this lock's smaller design means you won't be able to hook it around your bike's frame, wheel, and whatever sturdy piece of street furniture you're attaching it to, but you could supplement it with an additional Kryptoflex cable if you like.

5. Kryptonite New York Fahgettaboudit Chain

A top-rated chunky chain lock to keep your bike safe all day

Specifications

Type: Hardened magnese steel chain
Weight: 15.25 lbs (6.92 kgs)
Security rating: Sold Secure Diamond

Reasons to buy

+
Excellent security rating
+
Links are 3T manganese steel
+
Pick and drill resistant

Reasons to avoid

-
Bulky and heavy
-
Has a tendency to scratch

This package includes the Kryptonite New York Fahgettaboudit Chain (with 14mm six-sided links) plus a 15mm steel shackle. Both elements are super strong, using hardened steel to ward off attacks. The disc-style cylinder locking mechanism is also pick-proof and drill-resistant. It has the same top-level security rating as the Kryptonite New York Fahgettaboudit Mini D-lock above. You can also use it to secure multiple bikes.

However, the chunkiness comes at a price, as this weighs 10.8lbs/4.91kg, which means it's better suited to locking your bike up at home than carrying it with you on the go. There's also a risk of the parts of the chain not covered by the nylon cover scuffing your paintwork if you're not careful.

6. Titanker Bike Lock Cable

Proof that cable bike locks can be a good investment

Specifications

Type: Stainless steel, self-coling cable with polyvinyl chloride cover
Weight: N/I
Security rating: N/A

Reasons to buy

+
Solid construction
+
Offers more locking freedom

Reasons to avoid

-
Might be longer than you need
-
Mounting bracket not so hot

Cable locks are known to be weak and easy to snip through with a pair of bolt cutters, but that's not the case with the Titanker Bike Lock Cable, which bucks the trend thanks to its durable steel core.

Unlike D-locks, this Titanker model offers between four and six feet of flexible freedom, allowing it to be threaded around, through or under a bike and a mounting point. The four-digit combination lock mechanism means there's no key to worry about. However, bear in mind that the cover is plastic rather than metal, making it less durable than more expensive, heavy-duty bike locks like those from Kryptonite.

It's not a lock that'll let you leave your bike outside day and night, but it's light, convenient, and a good choice for making quick stops. Better still, it can be easily attached to your bike's frame while you ride using the mount included.

7. Litelok One Bike Lock

A simple but effective bike lock that you can wear

Specifications

Type: Hardened steel alloy strap
Weight: 2.4 lb (1.1kg)
Security rating: Sold Secure Silver

Reasons to buy

+
Super convenient
+
Simple operation
+
Rubberized coating

Reasons to avoid

-
Limited flexibility
-
Quite small

Bike locks can be awkward, so having one that you can wear offers a great solution to awkward mounts and means you won’t scratch your frame. This LiteLok offers convenience on all fronts as it can be closed with a simple click. You’ll need one of the two supplied keys to unlock it again, but the click-and-go idea works a treat if you’re making a quick pit-stop while you’re out on a ride.

The LiteLok comes in three colours, Boa Green, Crow Black and Herringbone, and small, medium and large sizes. Although it’s good on the eyes, the LiteLok is robust too, with the composite strap able to fend off bolt cutters effectively and the hardened steel alloy lock housing proving very durable too. A neat take on the usual bike lock.

Abus Granit X-Plus 540 bike lock on white background

8. Abus Granit X-Plus 540

A premium bike lock in terms of design, build, and price

Specifications

Type: Hardened steel D-lock
Weight: 3.3 lb (1.5 kg)
Security rating: Sold Secure Diamond

Reasons to buy

+
Superior design
+
Premium build
+
Quality brand

Reasons to avoid

-
Quite hefty
-
Reasonably expensive

For some, the Abus brand is the last word in security, and this German-made lock certainly lives up to expectations. It’s big, beefy and feels very well engineered, with a construction that looks very able to fend off attacks. The trade-off for this is its weight, which at 3.30lbs/1.45kg makes it pretty heavy to lug around. Although considering its brilliant capacity for deterring thieves, that may well be a cost worth paying. 

The other aspect is its price tag, which is not cheap. Again though, if you have a very valuable bike, then the cost of the Abus Granit X-Plus 540 is probably going to feel relative. The design is superb, and the use of hardened German steel is a big part of the appeal. Meanwhile, the neat double-bolted shackle makes it a nightmare for thieves to cut through—one of the best.

9. Seatylock Foldylock Compact

A compact bike lock that's easy to stash away

Specifications

Type: Hardened steel foldable link lock
Weight: 2.2 lb (1 kg)
Security rating: N/A

Reasons to buy

+
Clever design
+
Rust resistant
+
Automotive standard keys

Reasons to avoid

Folding won't work for everyone

The Foldylock Compact is just one of a range of innovative locks from this brand, and it’s exactly what the name suggests. Bike locks can be unwieldy and, in some cases, a pain to store when they’re not in use. Foldylock has come up with a neat twist on the bike lock design by producing something that can be stored easily; plus, its weight (2.2lb/1kg) makes it reasonably portable too.

The collapsible design is comprised of hardened steel plates, which make it suitable for harnessing your bike around larger objects, such as lampposts or cycle racks. Likewise, there’s a quality feel coming from the lock, which comes with three Sidewinder keys, which have been cut by laser. Add it all together, and you’ve got a practical bike lock that also impresses with its use of rust-resistant components.

10. Abus 770A SmartX Keyless U-Lock

A smart lock that's ideal for securing your valuable e-bike

Specifications

Type: hardened square shaft parabolic U-lock
Weight: 4.4 lb (2 kg)
Security rating: N/A

Reasons to buy

+
Smart tech locking
+
Usual Abus build quality
+
Alarm function

Reasons to avoid

-
You’ll need your phone too

While Abus is well respected for its range of conventional bike locks, it has also ventured into the high-tech world with this smart system option. You get all of the trademark Abus design features, as seen on the excellent Granit, and that means a nifty parabolic shackle and hard-as-nails construction. The big difference, however, is the locking system that uses tech to take control.

There’s a keyless Go card that allows you to register yourself as an administrator and pair the device to your phone. From there, the Abus app and Bluetooth functionality deliver quick and easy control of the locking mechanism. There’s even an alarm, too, while the app can also help you find your bike if you’ve parked up and can’t remember where you left it. It happens. Clever stuff.
