A reliable bike lock is an essential investment to protect your bicycle or e-bike. However, with the vast array of models, security levels, and lock types available, making a choice can be overwhelming. This article serves as a practical guide. It explains the key differences between common lock types and presents a selection of models for various needs, helping you make an informed decision for your specific situation.
The right lock depends on several factors, including the value of your bike, how long you typically park it, and where you leave it. The following points will help you define your priorities.
The most common types are spiral, chain, U-locks, and folding locks. A spiral cable lock is lightweight, flexible, and well-suited as basic protection for short stops in low-theft areas. For a higher level of bike security, especially for more expensive bicycles or as an e-bike lock, a bike chain lock made of hardened steel offers significantly better protection against tampering. As a rule of thumb: the more valuable the bike, the more robust the lock should be.
Some locks feature recognised quality seals. Seeing an ART-certified bike lock means it has been tested for its resistance to theft by the Dutch ART Foundation. This certification is often required by insurance companies to cover a bicycle against theft. The number of stars (e.g., ART****) indicates the security level. Look for materials like hardened special steel, as it is more resistant to sawing, cutting, or drilling.
Besides security, practical handling is crucial. A long lock offers more flexibility to secure your bike to lampposts or wide railings. Weight is a factor if you transport the lock daily. A bike lock with a mount can be a convenient solution, as it attaches directly to the frame and is always within reach without taking up space in your backpack.
Here is a selection of bike locks that cover different security requirements and usage scenarios.
What makes it stand out This spiral cable lock from Prophete combines flexibility with practical handling. With a length of 150 cm, it offers plenty of room to secure the bike to various objects. A key advantage is the included saddle clamp mount, which allows the lock to be transported directly on the bike.
Advantages
Who is it for? Ideal for owners of city bikes or less expensive bicycles who are looking for a straightforward and lightweight security solution for short errands or stops in areas with a low risk of theft.
What makes it stand out The Grifema chain lock represents a solid balance of security and flexibility. The 7 mm thick chain links made of a zinc alloy offer good protection. The chain is sheathed in a durable nylon fabric that protects the bike's paint from scratches. A water- and dust-proof cover protects the lock cylinder from the elements and extends its lifespan.
Advantages
Who is it for? For bike owners who need reliable bike security for daily use in urban areas and are looking for a good middle ground between weight and security level.
What makes it stand out This chain lock from Prophete was specifically designed for high-security needs, as confirmed by its ART** certification**. The chain is made of hardened alloy steel with a diameter of 10.5 mm, providing a very high level of protection against tampering. Practical details like a dust cover and a lighted key for use in the dark complete the package.
Advantages
Who is it for? Indispensable for owners of expensive e-bikes, cargo bikes, and high-value bicycles who need provably high theft protection and must meet the requirements of their bike insurance policy.

The ART certification is an independent quality seal from the Dutch ART Foundation. Locks are tested for their resistance to theft attempts. The rating is given in categories from 1 to 5 stars. An ART-certified bike lock with a high star rating (e.g., 4 or 5 stars) offers a very high level of security and is often required by insurance companies for the theft protection of e-bikes and expensive bicycles.
To secure your bike effectively, you should always pass the lock through the frame and, if possible, through a wheel as well. Lock it to a fixed, immovable object, such as a bike rack, a solid railing, or a lamppost. Avoid locking the bike by the front wheel only, as it can be easily removed.
Due to their high value and increased risk of theft, a high-security lock is recommended for an e-bike. A robust bike chain lock, a solid U-lock, or a folding lock made of hardened steel are the appropriate options here. Pay special attention to an ART certification (at least ART** or higher), as many insurance policies require this for e-bike coverage.
