Finding a stolen bike in France: what really helps
No one can promise to find a stolen bike. A complaint, a bike that can be identified and an eye on the listings improve the odds.
What are the chances?
They are low, and that needs saying.
According to the FUB, the French federation of bike users, only 2 to 3% of theft victims get their bike back when it is not marked. For bikes that are marked and reported stolen in the national register, France’s Ministry of Transport counts 11.4% found in 2024, against 10.3% in 2023 (answer to a parliamentary question, February 2025).
The two figures are not measured the same way: they cannot be compared directly.
First, the complaint
The complaint is what reports the theft to the authorities. Your insurer asks for the récépissé (the receipt you get when you file). And if the police seize the bike, you ask for it back with your proof, including the procès-verbal (the police’s written record of your complaint).
The day a listing appears, you will go to the police with your complaint reference. See reporting a bike theft in France.
Marking: so a bike that is found comes back to you
According to the FUB, more than 150,000 bikes are found abandoned. Someone still has to know whose they are.
A marked bike is linked to your contact details in the FNUCI, France’s national register of marked bikes. The police, the gendarmerie (France’s other police force), the municipal police, lost property offices (objets trouvés) and pounds (fourrières) can check it and reach you.
If your bike is marked, report the theft to the marking operator and check your contact details. If it is not, call your town’s lost property office and pound yourself. See bike marking in France.
The serial number and the invoice
The serial number is often engraved or stuck under the bottom bracket (where the pedal cranks go through the frame). It is sometimes on the invoice. Together with the invoice, it is what proves the bike is yours.
Put it in the complaint. Without it, a bike that is found looks like many others.
Photos
They help three times: to describe the bike in the complaint, to recognise it in a listing, and when the police look for owners.
In February 2026, near Lyon, the gendarmerie released a video of bikes found in a lock-up garage. It asked victims to come with an invoice, a serial number, photos or a complaint (LyonMag).
Look through your phone for photos that show details: a scratch, a sticker, an accessory.
Listings
Many stolen bikes are resold online. You have to look every day, on several sites, and not only near home. See stolen bike for sale on Leboncoin.
Retrace compares the photos of your bike with the listings on the sites it covers and alerts you when a bike for sale could be yours. It does not see every listing, nor private groups. It cannot promise to find the bike.
The police, for what comes next
When the listing is there, go to the police with the listing, your complaint and your proof. Then set up the meeting with the seller in agreement with them: they assist you at the handover.
What does not help
- going to the meeting alone, or setting it up without telling the police
- buying back your own bike
- reporting the listing to the site before you have seen the police
- waiting to file a complaint
