FietsRadar

A bike is reported stolen in the Netherlands every 6 minutes.

Get your stolen bike back — with the whole neighbourhood

Register your bike for free. If it is stolen, it is on the live map within minutes, people nearby are alerted and you share a poster. When someone spots it, FietsRadar puts them in touch with you.

Protect my bike — freeBuying second-hand? Check a frame number

Free · No card · Your address and details are never shown to anyone.

Every pin is a bike reported stolen, and its owner is still looking.

How it works

  1. Register in a minute

    Frame number, a few photos, and the battery numbers of an e-bike. Purchase value and receipt stay private.

  2. Stolen? Raise the alarm

    Report it and your bike appears on the live map. People with an alert area nearby are told, and you get a poster to share anywhere.

  3. Found through other people’s eyes

    Anyone who spots it can report it. If the frame number matches, you hear straight away and talk inside the app, without sharing a phone number.

I am buying a second-hand bike

A cheap bike can be a stolen one. Check the frame number before you pay. No account needed.

Check a frame number

One frame number, three registers

A buyer checking only one register has checked the smallest one. The free check covers all three on one page.

FietsRadar

Our own register of bikes reported stolen, checked instantly.

RDW bike-theft register

Municipal bike depots

Bikes the council removed. We tell you how to search them, and can check them for you.

Your details stay yours

Others see

  • Photos, brand, colour and type of the bike
  • Roughly where and when it was stolen

Nobody else sees

  • Your name, email address, phone number or address
  • Purchase value, locks and receipt
  • Where your photos were taken: we strip the location from every upload

Free, and it stays free

Registering, reporting, alerts, posters, the frame-number check and a depot check are all free, with no card to enter. Want the depots checked for you every day? That is an optional plan from €2.99 a month, cancellable any time.

Frequently asked questions

Is FietsRadar really free?

Yes. Registering bikes, reporting a theft, alerts, posters and the frame-number check cost nothing, and there is no card to enter. Only the optional daily depot check is paid.

Do I still need to report a theft to the police?

Yes, always. FietsRadar is not the police. We prepare your details for the report at politie.nl, and that report is what puts your bike in the RDW register and what your insurer asks for.

What do other people see about me?

Nothing that identifies you. A poster shows the bike, not its owner, and a finder talks to you inside the app without seeing your email address or phone number.

How does someone who finds my bike reach me?

They report the bike they saw. If its frame number matches yours, you are told at once and a conversation opens. A look-alike without a frame number is passed on only after the finder confirms it.

My bike is gone. Could the council have removed it?

Quite possibly. Dutch municipalities remove tens of thousands of wrongly parked bikes a year and keep them in a depot for a few weeks. FietsRadar searches the national lost-and-found register for you.

Can I check a second-hand bike before I buy it?

Yes, without an account. Enter the frame number and see in seconds whether it is reported stolen, then check the RDW register in one more step.

Does it work outside Amsterdam?

Yes, everywhere in the Netherlands. The more people near you use it, the more eyes there are on your bike, so tell your neighbours.
