Laws and regulations
What the StVZO says
The StraĂźenverkehrs-Zulassungs-Ordnung (StVZO) clearly regulates in Germany which lighting is required on bicycles. These provide us with the framework for product development, within which we develop the best possible solutions for your safety on the road.
1

white light
It's mandatory to have a white front light with a clearly defined beam that does not dazzle.
2
red rear light
You always need to have a red rear light that is continuously lit. It's not allowed to have a flasing mode.

reflectors
There a multiple reflectors that are mandatory on your bike
- Front side: white
- Rear light: red
- On each padel: yellow
- Side: yellow (spoke reflectors or reflective strips on the tire)
Did you know?
When visibility is reduced (dusk, darkness or poor weather), the lighting must be switched on. Violations can result not only in a fine but, in the event of damage, in shared liability. That can get expensive fast!

Particularly important: Only lights with an approval mark (“K‑number”) are permitted for road use. At TRELOCK this marking is of course part of every approved product.
Bicycle security – legal vs. practical aspects
What does the police recommend?
Tips
There is no legal obligation to lock a bicycle. It is also theft if the bicycle was not locked. Nevertheless, from an insurance and liability point of view it is crucial to use an appropriate lock if you want to have your bicycle replaced.
Important: Insurance companies will only recognize a theft as covered if the bicycle was “adequately secured.”
What “adequately” means depends indeed on the value of the bicycle. For high-value e-bikes, tested U-locks, chains or folding locks are recommended.
A simple coiled cable lock is generally not considered sufficient security, but only an additional measure. Security certificates such as ART, Sold Secure, or Varefakta can indicate whether a lock is considered adequate by insurance companies. Please refer to your insurance documents to find out what your insurance company requires. This can vary greatly from region to region. Requirements range from a lock value of at least €49, as is often the case in Germany, to two certified locks in the Netherlands.
fixed objects
Always lock the frame to a fixed object (bike stand, lamppost with concrete foundation, etc.). Position it in a way that the lock connects the frame and at least one wheel to the fixed object. If possible, include the rear wheel — it is harder to remove than the front wheel.


Use 2 locks
For extra security, use two locks, if possible two different types (e.g. U-lock + chain), because different tools are needed to break them and thieves will need more time or may not even have the right tools for both. Make sure the lock fits tightly to the bike. That way levering or cutting tools have less access to the lock.
Conclusion
Whether lighting or anti-theft protection — both topics are closely linked in practice: safety arises from responsibility. With a StVZO-compliant lighting system and a certified lock you not only comply with the law but also rely on tested safety. This way, you are not only protecting yourself, but also your bike and other road users.
