Claim for damages after a bicycle accident

Questioner

Someone just crossed the road cycling on an ebike. He had shark teeth on his turn on the cycle path. I was driving on the priority road with a car I swerved to avoid this cyclist and crashed into a pole on the traffic island. I have exchanged information with this person. But he does not respond to telephone contact (anymore) I want to claim my damages from his insurance. But I don't know where he is insured. My liability insurance does not give advice/do anything. The car insurance for the car I was driving is not in my name. What should I do? What rights and/or obligations do I have?

Lawyer

It is difficult if the cyclist does not respond. If you have an address, I advise you to hold him liable for the damage in writing. Otherwise, you will have to try to trace the cyclist by means of witnesses, images (on social media), etc. If you do not succeed, the chance that you can still recover your damages from this cyclist is small.

Questioner

I have the cyclist's address and telephone number, etc. How do I hold him liable in writing? Is that by means of a standard form or something? If yes, how do I get that. Can you provide me with that? Or help me on my way? I am not familiar at all in this world of damages and liability, etc. So all tips and help are more than welcome. In any case, thank you very much for your response/help!
