How Do You Lock a Bike to Keep It Safe From Thieves?
A strong bike lock only works if it catches the right parts of the bike. The best way to lock a bike is to secure the frame and both wheels to a fixed stand, preferably with two good-quality locks. Keep them tight against the bike and stand so there is little room for tools.
This guide explains how to securely lock a bike in public and at home. It also covers lock types and what to check if bike theft insurance applies.

How to Lock a Bike Properly
To lock a bike properly, you should start with the anchor point, as a thick lock attached to a weak railing still leaves the bike exposed. Choose a cycle stand that is firmly fixed to the ground, then check that the bike and closed lock can't be lifted over it.
Follow these steps to secure the bike:
1
Place the bike close to the stand so there is little space between them.
2
Fit the main lock around the stand, the bike frame and the rear wheel if its size allows.
3
Use a second lock to secure the front wheel and frame to the stand.
4
Keep both locks away from the ground and fill as much of the space inside them as possible.
5
Remove accessories that detach without tools, such as lights or bags.
6
Pull on the stand and both locks before leaving to check that everything is closed and secure.
If one lock won't reach around the frame, rear wheel and stand, prioritise the frame and stand. Secure both wheels with a second lock or cable. Locking only the wheel leaves the rest of the bike free to be taken.
⚠️
Quick-release wheels need particular attention.
Lock both wheels, replace the quick-release skewers with locking versions, or take the removable wheel with you.
Which Type of Bike Lock Should You Use?
When choosing a bike lock, don’t go by its shape or weight alone. The independent security rating gives a better indication of how it has performed under testing, and two similar-looking locks can offer very different levels of resistance.
| Bike security type | Suitable use | Points to consider |
|---|---|---|
| D-lock | Main lock for public parking | Rigid and difficult to position around large or awkward stands |
| Chain and padlock | Home storage or awkward anchor points | Flexible but often heavier to carry |
| Folding lock | Portable security where extra reach is useful | Check the independent rating of the specific model |
| Cable lock | Securing a wheel or removable accessory | Best used as secondary security, not the main lock |
| Ground or wall anchor | A fixed locking point in a garage or shed | Must be installed into a suitable solid surface |

Look for an anti-theft bike lock with a rating suited to the bike's value and any insurer requirement. Sold Secure rates approved pedal-cycle locks at Bronze, Silver, Gold and Diamond. Our Sold Secure bike-lock guide explains how these ratings compare.
You can also check the exact model in the Sold Secure approved product database before buying, as products from the same range don't necessarily share a rating.
D-locks
A D-lock, also called a U-lock, uses a rigid shackle that is easy to fit closely around the bike and stand. Less empty space gives leverage tools less room to work.
The Squire Matterhorn 230 has a 14mm hardened-steel shackle and a Sold Secure Pedal Cycle Diamond rating. The Squire Nevis 230 uses a 13mm hardened-steel shackle and is rated Sold Secure Pedal Cycle Gold. Both include a frame-carrying bracket.
Choose a size that fits the bike and the stands used most often. An oversized shackle is easier to position, but the extra room can make the lock harder to fit snugly.
Chains and padlocks
A chain reaches around thick posts and awkward anchor points more easily than a D-lock. It is also useful for locking several bikes at home, although a heavy security chain is less convenient to carry. Locks Direct stocks security chains in several lengths and link sizes.
Keep the chain tight and off the ground where possible. The padlock, chain and anchor should offer a similar level of security, as the setup is only as strong as its weakest part.
Folding locks and cables
A folding lock packs down neatly and gives more reach than many D-locks. Security varies by model, so compare its independent rating with the bike's value and insurer requirements.
Cable locks are light and flexible, but most don't provide the same attack resistance as a rated D-lock or chain. Use one to secure the front wheel or accessories alongside the main lock. The Squire 10C security cable is designed for this secondary role.
Where Should You Lock a Bike?
The stand is part of the security setup, so take a few seconds to inspect it when you’re locking a bike. Choose recognised cycle parking in a busy, well-lit area. CCTV or staffed parking adds oversight, but the bike still needs to be locked properly.
An inverted-U Sheffield stand gives space to secure the frame and wheels. Before using any stand, check that it is firmly fixed and has no cut or removable sections. Don't attach a bike to a tree, wooden fence, short post or temporary sign.
Avoid leaving the bike in a place where it blocks a pavement, entrance or access route. If parking at a station or workplace, check for a secure cycle store before using an outdoor stand.
How to Secure a Bike at Home
A closed garage or shed door shouldn't be the bike's only protection when securing a bike at home. Add a ground or wall anchor fixed into sound concrete or brick, following the manufacturer's instructions. The frame can then be secured to it with a suitable chain or D-lock.
The Squire GA6 ground anchor can be fixed to brick or concrete and accepts chains up to 26mm. It carries a Sold Secure Powered Cycle Diamond rating. The Abus WBA100 provides another fixed anchor option for wall or floor installation.
Keep the bike out of sight and lock the building itself. Record the frame number and keep a dated photo somewhere separate from the bike. Retain the purchase receipts for the bike and locks too.
Does the Bike Locking Method Change for a Short Stop?
There is no safe minimum parking time when locking a bike. Use the same core method for a quick shop visit as a longer stop by securing the frame to a fixed stand and protecting both wheels. An unrated cable lock shouldn't become the main lock simply because the bike will only be left for a few minutes.

There is no safe minimum parking time when locking a bike.
”For longer parking or valuable bikes, two different lock types add another layer of protection. Police bike-security guidance recommends double-locking a bike, with at least one D-lock, because different locks may require different tools to attack.
Outdoor overnight parking carries more risk. Use secure indoor storage where available. If the bike must stay outside, choose a well-lit recognised cycle park and use locks that meet the insurer's conditions.
Bike Theft Insurance and Lock Requirements
Insurance for bike theft often sets specific rules for the lock and the way the bike is secured. Missing one of those conditions can affect a claim, so check the wording before choosing a lock. Requirements differ between specialist cycle cover and home contents policies.
Before leaving the bike, check the policy wording for:
The required Sold Secure rating for the bike's value
The definition of an immovable object
Any restrictions on overnight or unattended storage
The evidence needed for a claim, such as proof of ownership and lock details
A lock described as secure or approved in general may still fall below the rating stated in a policy. Follow the insurer's exact conditions and keep the receipt for the lock. If the requirements aren't clear, ask the insurer to confirm them in writing.
Common Bike-Locking Mistakes
Before walking away from your bike, spend a few seconds checking the full locking setup. These are the mistakes that leave an easy route around the lock:
Locking only a removable wheel
Using a cable as the only lock
Attaching the bike to an object that can be cut, lifted or dismantled
Leaving enough empty space inside the lock for larger tools
Resting a chain or lock on the ground, where it has a firm surface beneath it
Leaving quick-release parts and accessories unsecured
Check the lock regularly for damage or corrosion, and test that the mechanism works smoothly. Use the maintenance product recommended by the manufacturer rather than applying an unsuitable oil to the cylinder.
Choosing the Right Bike Security
The right setup should be easy enough to use on every ride and strong enough for the places the bike is left. It must also meet any insurance conditions.

Frequently Asked Questions
Find direct answers to common questions about how to lock a bike properly, choose a suitable lock and meet common insurance conditions.
What is the best way to lock a bike?
The best way to lock a bike is to secure the frame and both wheels to a fixed cycle stand. Use a rated D-lock or chain as the main lock, then add a second lock for the remaining wheel. Fit each lock tightly and keep it off the ground.
How do you securely lock a bike with one lock?
Pass a suitably sized D-lock around a fixed stand and through the bike frame. Include the rear wheel if the shackle reaches without leaving excessive space. The frame must stay attached to the stand, as locking a removable wheel alone does not secure the bike.
How do you lock a bike with quick-release wheels?
Secure both quick-release wheels as well as the frame. Use a second lock for the front wheel, fit locking skewers or remove the front wheel and place it beside the rear wheel so the main lock can secure it with the frame.
Is it worth using two bike locks?
Yes. Two locks help secure the frame and both wheels, while different lock types may require different tools to attack. This setup is particularly useful for a valuable bike, longer parking or any location where the bike will be left out of sight.
Are D-locks better than chain locks for bikes?
A D-lock is not automatically better than a chain. Compare the independent security rating of the exact product. D-locks are easy to fit closely around a stand, while chains offer more reach around thick posts or awkward anchor points.
Can you use a cable lock as the main bike lock?
Most cable locks are better used as a secondary lock for a wheel or removable accessory. For the main lock, choose an independently rated D-lock, folding lock or chain that suits the bike's value and meets any bike theft insurance conditions.
What Sold Secure rating do you need for bike insurance?
The required Sold Secure rating depends on the insurer, policy and bike value. Check the current policy wording before buying a lock, then confirm the exact model in the Sold Secure database. Keep the lock receipt in case proof is needed for a bike theft insurance claim.
