Bike Lock Guide: How to Find the Right Protection for Your Bike

A reliable bike lock is a fundamental investment in protecting your bicycle. However, with the vast array of models, security levels, and locking mechanisms available, the selection process can be overwhelming. This guide is designed to help you understand the features of different bike locks and make an informed decision tailored to your bike's value and your individual needs.

What to Look for When Buying a Bike Lock

To find the right lock, it's helpful to consider a few basic criteria. These factors determine how well a lock protects your bike in daily use and how practical it is to handle.

The Right Lock Type for Your Needs

The design of a lock has a direct impact on its security and flexibility.

• Coil Cable Locks: These are lightweight, flexible, and often affordable. They are suitable for short stops in low-risk areas or as a secondary lock to secure components like the front wheel. A coil cable lock with a mount can be conveniently transported on the bike.
• Chain Locks: Composed of solid steel links, they offer a high level of protection. A robust chain lock is an excellent choice, especially for expensive bicycles like e-bikes, as it resists attacks from tools such as bolt cutters. Their heavier weight is the trade-off for increased security.
• U-Locks and Folding Locks: U-locks are considered very durable but are rigid and less flexible for locking up. Folding locks offer a good compromise between the security of a U-lock and the flexibility of a chain.

Understanding Security Levels and Certifications

For a high-security bike lock, independent certifications are a key indicator. The Dutch ART-certified lock is a recognised standard in Europe. The ART Foundation classifies locks into different security levels (indicated by stars). Many insurance companies require a lock with a specific ART certification (e.g., ART** or higher) for theft protection on high-value bicycles.

Everyday Use: Key or Combination Lock?

The choice between a keyed and a combination lock is often a matter of personal preference.

• Combination Lock: The advantage is obvious—you can't lose a key. Modern locks with 5-digit codes offer up to 100,000 possible combinations, providing high security against code guessing.
• Keyed Lock: Many users find locking and unlocking with a key to be quicker and more straightforward. High-quality cylinders are protected against picking and drilling. A spare key is often included, sometimes even with an integrated light for easier use in the dark.

Our Recommended Bike Locks

Here is a selection of locks that meet different requirements for security and handling.

Prophete Coil Cable Lock 150 cm with Saddle Clamp Mount

Why It Stands Out This lock combines a generous length with practical accessories. The included saddle clamp mount ensures the lock is always with your bike and never forgotten.

Pros

• Length: At 150 cm, it offers enough room to secure the bike to lampposts or wider railings.
• Flexibility: The coil cable is very pliable and easy to handle.
• Portability: The saddle clamp mount allows for rattle-free and secure transport directly on the bike.
• Diameter: The cable has a diameter of 8 mm.

Who It's For For owners of city or utility bikes who need a simple and lightweight lock for short errands in areas with a low risk of theft. It's also a great option as a secondary lock for securing a helmet or the front wheel.

Grifema Bike Lock, 5-Digit Combination, 120 cm

Why It Stands Out The Grifema lock uses a 5-digit code, which, with 100,000 possible combinations, offers significantly higher security than the more common 4-digit versions.

Pros

• Security Mechanism: The 5-digit combination lock is individually programmable and makes unauthorised opening considerably more difficult.
• Keyless: Ideal for anyone who prefers not to carry keys.
• Material: According to the manufacturer, the locking mechanism is made from a robust zinc alloy.
• Length: A 120 cm length provides good flexibility for locking up.

Who It's For For cyclists who appreciate the convenience of a combination lock and need a solid security solution for their mountain bike or high-quality city bike in areas with a medium risk of theft.

Prophete E-Bike Chain Lock 90 cm, ART**** Certified

Why It Stands Out This e-bike chain lock features an ART** certification**, making it a top choice among high-security bike locks. This certification is often required by insurance companies for the protection of expensive bicycles.

Pros

• Certification: The ART** certification** (4 out of 5 stars) attests to a very high level of protection against theft attempts.
• Material: The chain links, with a 10.5 mm diameter, are made from hardened alloy steel, according to the manufacturer.
• Practical Details: A dust cap protects the cylinder from dirt, and one of the two included keys is illuminated.
• Protection: The textile sleeve around the chain protects the bike frame's paintwork.

Who It's For This lock is specifically aimed at owners of high-value bicycles, pedelecs, and e-bikes who need to park their bike in high-risk areas or want to meet the requirements of their bicycle insurance policy.

Frequently Asked Questions

How do I lock my bike correctly?

Always lock the frame and, ideally, the rear wheel to a solid, immovable object (e.g., a bike rack, lamppost, or sturdy fence). Avoid locking only the front wheel, as it can be easily removed.

What does the ART certification on a bike lock mean?

The ART Foundation is a Dutch organisation that tests and certifies mechanical security products. The rating is given in stars (1 to 5). An ART-certified lock has passed standardised tests that assess its resistance to break-in attempts. The more stars, the higher the protection.

Is a combination lock or a keyed lock more secure?

Security depends not primarily on the type, but on the quality of the locking mechanism and materials. There are both highly secure keyed locks with complex cylinders and highly secure combination locks with many possible combinations. The decision ultimately comes down to personal preference for convenience and handling.
