Bike theft is the most common crime in Amsterdam, and you pretty much never get your bike back. But here’s something that might change that, an engraving service. For free – so bound to be popular with the Dutch.
You’ll need ID, and they’ll engrave your bike and register it as yours, if your bike is later stolen and recovered it’ll be brought back to your home for no charge.
Great system, shame I didn’t have my bike with me.
