No, not with a big stick

We’ve probably all suffered from scallywags stealing bikes, or know someone who has. Here’s how to prevent it. Plus: four of the best mountain bike locks.

>>> The UK’s top ten worst bike theft spots

1. Think like a thief

Unpleasant, but necessary. Spend some time looking at your shed or garage in a new light, and think about the weak points. “They don’t care about collateral damage,” says Steve Briggs, who designs top end bike locks for engineering firm Pragmasis. “We know of a case where thieves attacked six bikes that were chained together and the owner thought he didn’t need a ground anchor — the thieves hacked through five frames to get one bike out, with the chain still attached.”

Do you leave a spade next to the shed that could be a handy crowbar? Are there windows so thieves can see what’s inside? Is your garden gate old and falling off its hinges? Grab your virtual swag bag and probe your property for weak points.

2. Do the simple stuff

Security screws with rounded ends that secure hinges, bolts and padlocks to sheds — they don’t work. “Thieves don’t muck about with screwdrivers, they use a crowbar and rip it all out,” Steve says. Replace them with long, round-headed coach bolts that secure on the inside to a bolt with a washer, with one bolt on each side of the hinge and one bolt on each side of any lock. “It doesn’t cost much to do that, but all of a sudden the thief has to work hard,” Steve says. “In terms of overall cost effectiveness things like this are the best.” Think gravel, spiky plants and lights too.

3. New locks and bolts

Simple sliding bolts with a padlock are vulnerable, replace them with a hasp and staple — that’s the thing with a flap of metal that shuts over a ring bolt. “Get a good one, sometimes the staple is so slim it can be cut with bolt cutters, Steve says. “And make sure the staple is vertical, not horizontal, because it lets the padlock hang downwards and not stick up, inviting attack.”

Up and over garage doors are pretty puny, but if you’ve got another way in to the garage it’s easy to just put sliding bolts on the inside. If not, buy some garage locking door bolts from

What about a Garage Defender? “It’s tricky,” Steve says. “If you’re a row of six lockups and everyone has one, get one. If you’re the only one who’ll have one, then don’t get one because it’ll advertise you have something in there. Then again, if you’ve already had a theft then get one, because they know you have valuable stuff and there’s a pretty good chance they’ll come back.”

4. Inside job

If the thief gets inside your garage or shed you need level two security. “You’re always looking to tie the bikes down, get a ground anchor and chain,” Steve says. Locks are heavy though so make sure you invest in something you can handle, and actually use it, rather than something huge and clunky that gathers dust. “The idea is for the thief to take one look and walk away.” Ideally use more than one type of lock (chain, D-lock etc) and secure your bikes through the frame and wheels too.

5. Don’t advertise

“Don’t advertise what you’ve got,” Steve says. So no stickers on the windows of your shed, car, van and so on, and don’t work on your bike on the front drive. Do anything you can to make your stuff look uninteresting too.

“If people are careless on social media thieves can tell where you live, and see what bikes you’ve got too,” Steve says.

So should you shout about how much security you have? Yes and no, Steve says. You don’t want it to draw people in so it needs to be unobtrusive from a distance. “But it needs to be bloody secure and obviously so if someone’s close up and in your garden looking around.”

Four of the best mountain bike locks

1. Ground anchor: Kryptonite Stronghold Anchor


Great for tying your bikes to, the Kryptonite Stronghold Anchor has a 16mm hardened carbon alloy steel shackle. Set it into concrete, but make sure it’s in the right spot because there’s no getting it out again.

2. Chain and lock: Kryptonite Evolution Series Integrated Chain


Goes perfectly with the ground anchor, Kryptonite’s Evolution Series Integrated Chain hides the padlock away in the end of the chain so there’s less to attack. Comes in a range of lengths.

3. Alternative anchor: Pragmasis Shed Shackle


What about if you’ve got no concrete floor for an anchor… The Shed Shackle from Pragmasis reinforces a large area of shed wall, meaning a thief has to cut or smash out a huge section if they want the Shackle out.

4. Metal shed: Asgard Access E Plus


Investing in a shed? Asgard makes some of the best, like the Access E Plus that features charging points for e-bikes (or your lights or Di2 if you’re not into e-bikes). It’s made from weatherproof steel and weighs 19 stone so there’s be no shifting it when it’s anchored to the ground.
