Why the right bike lock matters

The right lock protects your bike from theft and gives you the confidence to leave it anywhere.

  • Certified protection: Locks with ART, VdS, or Sold Secure certification give you clear, reliable guidance.
  • Flexible locking systems: Key, combination, or smartphone access lets you share your lock with family or friends.
  • Smart features: Alarm functions over 100 dB and app connectivity give you more control in everyday use.

Bike lock types at a glance

Bicycle locks differ in design, security level, and handling. Solid U-locks deliver the highest level of theft protection. Chain locks and folding locks stand out for flexibility when securing your bike, while lightweight cable locks are ideal for securing wheels or accessories. The right type depends on your bike, where you park it, and your daily routine. As a general rule, you should invest around 5 to 10% of your bike’s original price in a good lock. If you ride a high-value bike, it’s worth investing more.

D locks (U-locks)

The classic bike lock. A solid shackle made of hardened steel protects your bike against bolt cutters and leverage attacks. D locks regularly achieve the highest security ratings – alongside heavy chain locks. For high-value bikes in urban areas, a D lock is one of the most secure choices.

Folding locks

Flat-folding steel segments in a compact, ruler-style design that mount directly to your frame. A folding lock gives you solid security in a compact, easy-to-carry design. Unfolded, it gives you enough reach to secure the frame and wheel together or lock your bike to a fixed object.

Chain locks

Chain locks offer maximum flexibility when securing your bike. Their length makes it easy to lock both the frame and wheel to a rack or post. A fabric sleeve around the hardened steel links protects your frame from scratches. As a rule: the thicker the links, the higher the security – but also the more weight and bulk you carry.

Cable locks

Lightweight, affordable, and flexible – cable locks are best used as a secondary lock or for short stops. On their own, they’re usually not enough for high-value bikes. Use them alongside a primary lock to secure wheels, the saddle, or accessories like your helmet.

Frame locks

Mounted directly to the rear triangle, frame locks quickly immobilize your rear wheel with a steel shackle. Especially popular on city bikes, they provide basic theft protection. For full security, combine it with a second lock to secure your bike to a rack or post.

Lock accessories for your bike

Plug-in chains, mounts, and extension cables expand how you can use your bike lock. A plug-in chain for a frame lock lets you secure your bike to a rack or post, while sturdy frame mounts keep your lock secure and help reduce rattling. Want to secure your bike at home as well?

Choosing the right bike lock

Buying a bike lock means assessing your theft risk realistically. Where do you park your bike? For how long? And how much is it worth? The clearer your answers, the easier it is to choose the right lock. For high-value bikes and e-bikes, insurance also plays a key role – many providers require a certified lock to cover theft.


What level of security do I need?

It depends on your bike’s value and where you park it. As a rule of thumb, invest around 5 to 10% of your bike’s original price in a lock. Manufacturer security ratings can help, but they’re not directly comparable. For e-bikes, locks with independent certifications like Sold Secure Gold, ART 2, or VdS are often the better choice. They’re tested to meet standardized theft resistance and are recognized by many insurers.

Which lock type fits my daily routine?

Your lock should be long enough to secure the frame – ideally also a wheel – to a rack or post. The more flexible the design, the easier it is to lock your bike to lampposts or bike racks. Weight and transport matter too. On a road bike, every gram counts. On a city or commuter bike, heavier locks are easy to carry with a frame mount or on a rack.

Which locking mechanism is best?

High-quality lock cylinders protect against picking and drilling, making them harder to tamper with. Combination bicycle locks remove the need for a key, which is useful if multiple people use the bike. Smart locks with Bluetooth apps offer a third option. They’re convenient but rely on battery life and a stable connection. Look for high-quality models with an emergency unlocking option.
