Generally, the heavier and more expensive the lock, the higher level of security it offers. The goal is not to make your bike impossible to steal, but to make it a difficult and time-consuming target.
Browse our full range of locks, from lightweight café options to high-security D-locks and anchors.
Shop all locksIf a lock comes with an extra cable, remember the lock rating usually applies to the main body only, not the cable. Use cables as an add-on, not your primary security.
Sold Secure ratings explained
Sold Secure is an independent testing house that manufacturers can submit security products to for testing and accreditation. Locks are assessed against different attack types, tools used, and time spent during the attack. We recommend choosing a lock that carries a Sold Secure badge.
BronzeBasic tool resistance for opportunist theft deterrence.
SilverEnhanced tool resistance for more determined attacks.
GoldDedicated tool resistance for higher risk areas.
DiamondHighest resistance, including specialist tools and severe attacks.
Lock types and what they are best for
Different locks suit different situations. If you commute and lock up in public every day, prioritise a higher security rating. If you only need a quick stop outside a café, a lightweight option can be convenient, provided you keep expectations realistic.
D-Locks (U-Locks / shackle locks)
D-locks are generally the most secure everyday option. The rigid shackle makes it harder to attack than flexible cables, and the compact shape helps you lock the frame to something immovable like a stand, fence, or rack.
More premium models typically include thicker hardened steel, strong anti-pick cylinders, and can sometimes feature alarms. If a lock comes with an extra cable, treat it as a secondary add-on for wheels or accessories.
Regular commuting, busy town centres, train stations, and higher-risk public locking.
Sold Secure Gold or Diamond where possible, a tight fit around the frame, and a quality lock core.
Folding locks
Folding locks aim to balance portability and security. They unfold from a compact case into a longer locking length, making it easier to reach awkward anchor points while remaining more robust than a basic cable.
The steel plates are designed to resist bolt cutters and other common attacks, and they usually come with high-security keys. Folded down, they are easy to carry on the bike using a bracket or in a bag.
Commuters who need more reach than a D-lock, or riders who want tidy on-bike storage.
A Sold Secure rating that matches your area, and a strong mounting bracket that will not rattle loose.
Cable locks
Cable locks are usually the lightest and most convenient to carry, but they are also typically the least secure. They come in different lengths and thicknesses, with either a key or combination lock.
Lighter options, sometimes referred to as café locks, are best treated as a short-stop deterrent rather than theft prevention. They can be handy if you are popping into a shop and keeping your bike in view.
Use a cable lock as a secondary lock (for example, wheels) alongside a stronger primary lock. If you regularly leave your bike unattended, consider stepping up to a D-lock or a higher-rated folding lock.
Chain locks
Chain locks are often the heaviest option and are commonly used at home to secure a bike in a shed or garage, usually alongside an anchor point. They typically feature a fabric sleeve to protect paintwork.
They are popular for high-security home storage and for riders who want a longer locking length around posts or ground anchors.
Home security, garages, sheds, and long locking reach with strong anchor points.
Weight and practicality. Many riders keep chains at home and use a lighter lock when out.
Anchors
Anchors are fixed to the ground or a solid wall in sheds, garages, workplaces, and secure storage areas. They give you a strong anchor point so the bike cannot simply be lifted and carried away.
Pairing an anchor with a quality chain or D-lock is one of the most effective ways to improve home security. Some options are insurance approved depending on the model and installation.
Frame locks
Frame locks are permanently mounted to the rear stays and lock through the back wheel to immobilise it. Some also allow a plug-in chain or cable to secure the bike to a fixed object.
They are convenient because the lock is always with you, but on their own they are not the highest security option. They are best used for quick stops, or as part of a two-lock setup where you also secure the frame to something immovable.
Shopping trips, short stops, and riders who want a built-in lock that is easy to use every day.
How to choose the right lock for your riding
Prioritise a strong primary lock such as a Sold Secure Gold or Diamond D-lock. Consider a secondary cable for wheels if you park for long periods.
A folding lock or solid mid-weight option can be a good balance. If you use a cable lock, keep the stop short and ideally keep the bike in view.
If you store your bike in a shed or garage, consider an anchor paired with a strong chain lock. This makes it far harder to remove the bike quickly.
FAQs
Yes. It gives you a consistent standard across brands and models. It is not a guarantee, but it is one of the best quick checks for comparing security levels.
Thicker cables can be better than very light café locks, but cables are still generally easier to attack than rigid locks. For regular public locking, a D-lock or higher-rated folding lock is usually a safer choice.
Two locks can be effective in higher-risk areas because it increases time and effort for a thief. A common setup is a strong primary lock for the frame plus a secondary lock for wheels.
The best lock depends on where you park and for how long, but many e-bike riders use a Sold Secure Gold or Diamond D-lock as the main lock, then add a secondary lock if needed.
Frame locks immobilise the wheel, which helps for short stops, but they do not secure the bike to an object. If you are leaving the bike unattended, add a chain or D-lock to anchor the frame to something solid.
Choose well-lit areas with strong, fixed bike stands where possible. Aim to lock the frame (not just the wheel) to something immovable, and reduce slack in the lock to make attacks harder.
