In short
Report the theft to the police (online or in person), have your frame number and proof of purchase ready, file a claim with your insurance company, and keep actively searching—both online and in person. If you’ve registered your bike beforehand, you’ll find it much faster.
The moment you see the empty bike rack is a bummer—there's no sugarcoating it. But those first few hours will determine how good your chances are. Take a deep breath and go through the following list.
01Quick check—is it really gone?
Before you panic: Could it be that your bike was just moved? Especially at train stations, in courtyards, or at events, security personnel sometimes move bikes or park them closer together. Take a look around the parking area and the immediate surroundings. If the spot is still empty, it’s time for Step 2.
02Find the frame number and supporting documents
Your most important “weapon” is the frame number —your bike’s unique identifier. Without it, your bike is just one of millions after it’s stolen; with it, it can be clearly identified. You’ll need it right away to file a police report and for insurance purposes.
So start collecting now:
- Frame number (if you didn't write it down: is it still on the receipt, the invoice, or in your bike registration card?)
- Proof of Purchase / Invoice (Value and Ownership)
- Photos of your bike (brand, model, color, special features)
- Brand, model, frame size, distinctive accessories
Tip: If you've registered your bike with BikePass, your frame number, photos, and digital proof of ownership are all stored in your account—you can share them directly with the police and your insurance company.
03File a police report
Reporting the theft is mandatory—not only so the police can investigate, but also because your insurance company almost always requires it. You have two options: You can find complete step-by-step instructions—both online and in person—in the guide “Reporting a Bicycle Theft.”
- Online Police Station: Most federal states offer an online police station where you can conveniently report the theft from home. Search for the “Online Police Station” or “Internet Police Station” for your federal state.
- In Person: You can file a report in person at any police station.
When filing the report, have the frame number, proof of purchase, location, and approximate time of the incident ready. Write down the case number —you'll need it for insurance purposes.
04Report a bicycle as stolen
To ensure your bike is identified if it turns up somewhere, it should be marked as stolen. You can mark your bike as stolen through your digital bike registration—that way, if it’s checked later (for example, before a used bike purchase), it will be immediately clear that it’s stolen property. This increases the chance that honest buyers will become suspicious and the bike will find its way back to you.
05Notify your insurance company—and do it quickly
Whether your home insurance (with a bicycle rider) or a separate bicycle insurance policy covers the damage depends on the terms of your policy. In any case, it’s important to note:
- Report the damage immediately —many contracts have deadlines.
- Enter the ad ID/file number, proof of purchase, and frame number.
- Pay attention to typical clauses: nighttime clauses, lock requirements, and compensation limits.
Check your policy to see if you’re covered and, if so, how much. Our guide “Home Contents Insurance for Bicycle Theft” explains when your home contents insurance covers theft—and when it doesn’t—while the page “Theft Protection for Bicycles” provides a comprehensive overview.
06Continue searching
Many stolen bikes turn up again—often at secondhand markets. Search systematically (you can find the complete strategy, including search alerts and the lost-and-found process, in the guide “Finding Your Stolen Bike”):
- Online classifieds and marketplaces (by make/model, including in neighboring cities)
- Local flea markets and secondhand bike shops
- Your City's Lost and Found Office and Bicycle Auctions (many municipalities auction off unclaimed bikes)
- Social Media / Local Groups – A Photo Plus a Frame Number Works Wonders
If you find your bike: Do not retrieve it yourself, and do not confront the seller. Notify the police and provide your case number and proof of ownership (frame number + registration).
07Planning for Your Next Bike
Once the acute stress has passed, it’s worth looking ahead. Three things can lower your risk and speed up the response time in an emergency:
- Register: Submit your frame number and photos digitally—free of charge and available throughout the EU.
- Marking: A visible mark on the frame acts as a deterrent and makes it easier to identify the bike.
- How to Lock Your Bike Properly: A Good Lock, Securing the Frame to a Sturdy Object—The guide “How to Lock Your Bike Properly” highlights the 8 most common mistakes.
The Emergency Aid Checklist: Just Check Off the Items
- Parking location and surrounding area checked
- Gathered the frame number, proof of purchase, and photos
- Report filed (online or in person) + case number noted
- Bicycle marked as stolen
- Notify Your Insurance Company (Note the Deadline!)
- Searched for online, locally, and at the lost and found office
