Your bike was stolen: what to do right now

You walk out of the supermarket, the office, or the café where you left it locked, and the bike is gone. The first minute is all anger and disbelief, but it's also the minute that matters most: what you do in the next few hours has a real effect on whether you get it back and how much you'll be reimbursed. In Italy alone, roughly 350,000 bikes are stolen every year, adding up to an estimated €150 million in damage — this isn't a fringe problem, and shops deal with its fallout constantly, often when a customer comes back to buy a replacement after losing a bike to theft. It's no accident that fear of theft puts off 72% of would-be buyers. Here's what to do, in order, from someone who works on these machines every day.

File a police report immediately — not just for insurance

A formal police report (not just an informal note) should be filed as soon as possible, ideally within 24 hours. You'll need it for insurance if you have coverage, but it matters even without one: it's the only way to get your bike into an official search loop, and it's the foundation for every next step, from recovery to any eventual payout. Bring everything you can: frame serial number, make and model, colour, any distinguishing parts (an unusual groupset, a non-stock handlebar), photos if you have them. The more detail you give, the more useful the report becomes.

The serial number is the key to everything

This is where most people trip up: a lot of riders have no idea where their bike's frame serial number is, let alone have it written down anywhere. It's the code — usually stamped under the bottom bracket — that uniquely identifies that specific bike, the equivalent of a car's licence plate. Without it, filing a theft report is harder, and proving ownership if the bike turns up becomes much harder still: whoever finds or buys a stolen bike has no way of knowing it's stolen, and whoever stops it on the street has no way to verify ownership unless there's a unique record somewhere to check against.

The practical takeaway, for anyone with a bike still sitting in the garage: get your trusted shop to log the frame serial number, along with the bike's key identifying details, before you ever need it. In Italy, an industry-backed registry effort (ANCMA) is built exactly around this idea — frame serial, a "CicloID," and a digital certificate of ownership — a system designed to make bikes traceable and harder to resell once stolen. If your bike has never been logged anywhere, the best time to do it was before the theft. The next best time is now, for every other bike you own.

Insurance: what you need and what to expect

If you're covered for theft — often bundled into home or liability insurance, or a dedicated policy for higher-value bikes — the standard process needs: a copy of the police report, proof of purchase or otherwise proof of value (receipt, invoice, older photos, any maintenance history documented by your shop), and the same detailed description you used for the report. Shops that keep a maintenance history tied to a bike's frame serial number are often the strongest source of proof of ownership and value a customer can hand to an insurer — if your shop has that record, ask for it right away, before too much time passes.

After the report: what you can do yourself

Post about the theft in local cycling groups and channels: plenty of stolen bikes get found because someone recognises them for sale online or spots them out and about, not through formal investigations. Check secondhand marketplaces in your area periodically. And if you recover your bike, or buy a used one, always check the frame serial number before going any further — it's the simplest, most effective check against the stolen-bike trade, for buyers and sellers alike.

Keeping track of a bike's serial number, maintenance history, and documents isn't only useful in case of theft — it's the foundation of a real bike passport, handy for warranty claims, resale, and everyday servicing too. If your regular shop uses CrankPal, ask them to log your bike there: it's a ten-minute job that makes all the difference on the day you actually need it.
