6 of the best bike locks — stop your bike getting stolen with our selection

Your buyers guide to the top-rated locks from £20

The '80s and '90s saw an arms race between bike lock makers and thieves that eventually settled down when manufacturers figured out how to make locks that would resist everything but hefty portable power tools. Here's our selection of bike locks that have the right stuff.

  • Good bike locks are heavy and expensive, but they're not as inconvenient as having your bike stolen

  • We recommend you go for a bike lock that's marked Gold on Sold Secure's bicycle rating system, and consider motorcycle Gold if you're parking in a theft hotspot like a train station or university campus

  • Carry two keys for your lock in separate places so you can still get moving if you lose one

  • Many insurance policies require you to use a high-quality lock or your claim will be denied

  • Prices for good bike locks start around £30

6 of the best bike locks for 2020

A sufficiently determined thief can breach anything. However, for the best bike locks 'sufficiently determined' means 'carrying a portable angle grinder'. That's not a cheap tool in itself, and while it's quick, it's also very conspicuous.

One technique of your professional thief is therefore to damage the lock so you can't open it, and then come back late at night with the big guns. If you find your lock mechanism made unusable — filled with glue, for example — break the lock yourself. Hiring an angle grinder will cost you about £20 for the day.

That's about the only way you'll quickly get through most of our selection here. The more you pay, on the whole, the longer it takes to breach a lock with unpowered brute force attacks, to the point where a thief won't bother with the best bike locks, but move on to easier pickings. It's a sad truth that the basis of on-street bike security is to make your bike too much trouble so a thief will nick someone else's.

Master Lock Street Fortum with cable — £28.99

Master Lock Street Fortum bonus pack

For 30 quid with a cable to help secure your front wheel the Master Lock Street Fortum is very good value in a lock that meets the Sold Secure Bicycle Gold standard. When we tested it, it resisted bolt-croppers and our persuader test, and the lock mechanism is well-protected from assault.

It can be broken, of course, but if you want a decent level of security at a sensible price for a round-town bike, it's a good choice.

Weight: 1,084g (lock only)

OnGuard 5000 Brute LS — £29.99

OnGuad Brute U lock

Its RRP is over £40, but the price above is more typical, which makes this tough cookie great value.

The Brute mates a 16mm hardened shackle with a bar made from a single piece of steel, and the locking mechanism is protected against drilling and picking.

In testing it resisted our standard armoury of 3ft bolt croppers, persuader, hammer, cold chisel, screwdriver and hacksaw. The 16mm shackle was too big for the jaws of our croppers so we went after it with the persuader and hammer but after five minutes the damage was pretty cosmetic, and the lock – with a slightly bent shackle – still worked fine.

Kryptonite New York — £70

Kryptonite New York 3000 U lock

The Kryptonite New York is plenty tough enough to repel most criminals and is a good choice for everyday use where bike security is a necessity.

It's not cheap, and it's heavy, but the New York pointed and laughed at our standard armoury. Nothing short of some quality power tools would make a dent in this lock.

Abus Granit X-Plus — £69.00

The Abus Granit X-Plus has long been among the best D locks on the market. It has Sold Secure Gold ratings for both bike and motorbikes (the latter is a higher standard) and it's not hard to see why.

We couldn't break this one with our standard thieves' armoury. The shackle is super stiff and no amount of cropping, twisting or thwacking would do any serious damage. the plastic sleeve got a bit mangled, but that was about it. Some meaty blows to the base broke off the plastic covering, but only to reveal a serious-looking steel plate construction that does a very good job of protecting the lock mechanism and was dismissive of our efforts. After all the violence was over the lock was still in perfect working order; even the plastic cover just snapped back on.

Squire SS50CS Stronghold Padlock — £64.95

Squire Stronghold padlock

In combination with a hefty chain, a good padlock will provide high-level security for home bike storage, though the substantial total weight makes it a bit impractical as carry-along theft prevention.

The Squire SS50CS is a well-designed, heavily armoured bike lock that's an excellent partner to some heavy-duty chain.

At 650g it certainly feels the part. It's engineered from a hardened steel billet with a 10mm shackle that's almost fully enclosed. The barrel is protected by another steel plate to protect against drilling, with the key turning just an eighth of a rotation to allow the protective sheet to cover more of the mechanism.

Pragmasis Protector 13mm security chain 2.0m — £78.75

Protector 13mm chain

Two metres of Protector 13mm chain weighs 6.95kg so you're not going to be carrying it around, but it's a great last line of defence for your home bike storage.

We couldn't touch it with bolt croppers, and a chain is inherently resistant to prying and hammering, especially a hardened steel chain like this.

Pragmasis offers a package of a 2m Protector with the Squire SS50CS Stronghold padlock above for £133.70.

Weight: 6,950g

Acknowledged by the Telegraph as a leading cycling journalist, John Stevenson has been writing about bikes and cycling for over 30 years since discovering that people were mug enough to pay him for it rather than expecting him to do an honest day's work.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history.

Since then he has worked on MTB Pro magazine and was editor of Maximum Mountain Bike and Australian Mountain Bike magazines, before switching to the web in 2000 to work for Along with editor Tony Farelly, John was on the launch team for and subsequently became editor in chief of Future Publishing’s group of cycling magazines and websites, including Cycling Plus, MBUK, What Mountain Bike and Procycling.

John has also written for Cyclist magazine, edited the BikeMagic website and was founding editor of before handing over to someone far more representative of the site's main audience.

He joined in 2013 and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
