In short
File a police report (online or in person), have your frame number and receipt to hand, report the loss to your insurer and keep searching actively – online and locally. If you registered your bike beforehand, you will get there much faster now.
The moment you see the empty bike stand is grim – there is no sugar-coating it. But the first few hours decide how good your chances are. Take a breath and work through the list below.
01Check quickly – is it really gone?
Before you switch into crisis mode: has the bike simply been moved? At stations, in courtyards or at events, staff often move bikes around or park them closer together. Walk around the spot and the immediate area once. If the space stays empty, it is time for step 2.
02Find your frame number and documents
Your most important “weapon” is the frame number – the unique identifier of your bike. Without it, your bike is one among millions after the theft; with it, it can be clearly assigned to you. You need it straight away for the police report and the insurer.
So gather the following now:
- Frame number (if you have not noted it down: is it still on the receipt, on the invoice or in your bike passport?)
- Receipt / invoice (value and ownership)
- Photos of your bike (make, model, colour, distinctive features)
- Make, model, frame size, noticeable add-on parts
Tip: If you have registered your bike with BikePass, your frame number, photos and digital proof of ownership are all bundled in your account – you can share them directly for the police report and the insurer.
03File a police report
The report is essential – not only so the police can search, but also because your insurer will almost always require it. You have two options: you will find the complete step-by-step instructions – online and in person – in the guide “Reporting a bike theft”.
- Online police station: most German federal states offer an online station where you can report the theft conveniently from home. Search for the “Onlinewache” or “Internetwache” of your federal state.
- In person: you can file a report in person at any police station.
When filing the report, have the frame number, the receipt, the location and the approximate time of the theft to hand. Note down the case reference number – you will need it for the insurer.
04Flag your bike as stolen
So that your bike is spotted if it turns up somewhere, it should be marked as stolen. Via your digital bike passport you can flag your bike as stolen – so during a later check (before a used purchase, for example) it is immediately clear that the bike is stolen goods. That increases the chance that honest buyers become suspicious and the bike ends up back with you.
05Tell your insurer – and do it fast
Whether your home contents insurance (with a bicycle add-on clause) or a dedicated bicycle insurance pays out depends on the contract. In any case, the following matters:
- Report the loss without delay – many contracts set deadlines.
- Submit the police report/case reference number, receipt and frame number.
- Watch out for typical clauses: night-time clause, requirements for the lock, compensation limits.
Whether and how much you get is settled by a look at your policy. When home contents insurance pays – and when it does not – is explained in our guide “Home contents insurance and bike theft”; the page Theft prevention for your bike gives an overall picture.
06Keep searching actively
Many stolen bikes resurface – often on used markets. Search systematically (you will find the complete strategy with search alerts and a lost property route in the guide “Finding a stolen bike again”):
- Online classifieds and marketplaces (by make/model, also in neighbouring towns)
- Local flea markets and used bike shops
- Lost property office in your city and found-bike auctions (many municipalities auction off unclaimed bikes)
- Social networks / local groups – a photo plus the frame number works wonders
If you spot your bike: do not take it back yourself and do not confront the seller. Inform the police and refer to your case reference number and your proof of ownership (frame number + registration).
07Be prepared for your next bike
Once the acute stress is over, it is worth looking ahead. Three things lower your risk and speed things up enormously if the worst happens:
- Register: store your frame number and photos digitally – free and EU-wide.
- Security marking: a visible code on the frame deters thieves and makes the bike traceable to you.
- Lock it properly: a good lock, frame attached to a solid object – the guide “Locking your bike properly” shows the 8 most common mistakes.
The emergency checklist to tick off
- Checked the parking spot and surrounding area
- Gathered frame number, receipt and photos
- Filed a police report (online or in person) + noted the case reference number
- Flagged the bike as stolen
- Informed the insurer (mind the deadline)
- Searched online, locally and at the lost property office
- For the next bike: registered, security-marked, locked properly
