Why Checking a Bike Matters

Buying a stolen bike can lead to legal issues, financial loss, and supporting criminal activity. Unfortunately, thousands of bikes are stolen every year, and many end up being resold online.

1. Check the Bike Serial Number

The most important step is to locate and verify the bike’s serial number. This is usually found under the bottom bracket or on the frame.

2. Use Online Bike Registries

You can check databases like Bike Index, Project 529, and Register.bike. These platforms allow you to search whether a bike has been reported stolen and help you verify key ownership details before buying.

3. Look for Red Flags

  • Price too low
  • No proof of ownership
  • Seller avoids questions

4. Ask for Proof of Ownership

Always ask for receipts, original documents, or registration confirmation.

5. Use a Global Bike Check Tool

The safest way is to use a global registry that combines multiple databases and helps detect stolen bikes across countries.
