How to Check if a Bike is Stolen: Step by step

Find the Serial Number on a Bike

Locating a bike’s serial number is the first step in tracking down whether or not it’s stolen. The vast majority of bikes will have a serial number stamped somewhere onto the frame. Some common places to find the serial number include:

Bottom bracket: Turn the bike upside down and look underneath the frame where the pedals attach.
Rear dropout: At the rear wheel axle.
Head tube: The top of the vertical part of the bike where the handlebars attach to the frame

In addition, if the bike’s serial number has been scratched off, this is a red flag that may suggest the bike is stolen.

Search Online Bike Registries

You can use several online databases to find out if a bike has been reported as stolen. These registries allow users to report stolen bikes, along with the serial number, make and model. Some trustworthy places to look are:

Scramblism: One of the most widely used global registries for stolen bikes.
Project 529: A nationwide registry where bike owners can register bikes and report thefts.
Local Police Databases Some law enforcement agencies offer online databases with listings of stolen property.

Just put the bike’s serial number or description into one of these platforms to find out if it matches up with any reported thefts.

Ask for Proof of Ownership

If you’re purchasing a used bike, always request that the seller provide proof of ownership. Legitimate sellers should be able to confirm:

Original receipt or invoice
Registration documents
Pictures of them with the bike

Beware of sellers who say they “just found” the bike or don’t have accompanying documents.

Look Over the Bike for Tampering

Look closely at the bike for signs of tampering, potentially a sign that it’s stolen. Red flags include:

Serial number scratched out or removed
Mismatch of components: Parts like wheels, handlebars or seats that don’t match the rest of the bike may have been replaced hastily.
Unusual paint jobs Some thieves repaint stolen bikes to disguise their appearance.

Research the Seller

Do your due diligence and check them out as best you can if buying a bike online or from a private seller. Research their profile on sites like Craigslist or Facebook Marketplace for:

Or a seller who has several high-value bikes listed at low prices could be fencing stolen property.
They refuse to meet you in public areas: Make it a point to meet in a safe, public location to complete the sale.

Search Local and Online Listings for Stolen Bicycles

Bike thieves are often looking to resell stolen bikes as quickly as possible, so it’s worth watching online marketplaces for comparisons. Perhaps you’re considering making a purchase, so compare the bike with:

Local community boards
Sales of stolen bikes on registries

Note stylings such as color, frame design and accessories.

Contact the Police

If you think the bike may be stolen, contact your local law enforcement agency. Give them the bike’s information, including the serial number and anything you have found. The police will simply query their own database to see if the bike has been reported stolen.

Look for Other Signs

Other less-obvious signs can indicate the bike is stolen, too:

Price too good to be true: If the seller is offering the bike for a fraction of what it’s worth, the bike could be stolen.
Quick flip: An eager seller is also a potential red flag — people selling stolen property want to dispose of it quickly.
