Where is the serial number on a bicycle?

The most common location is under the bottom bracket (the part where the pedals and cranks connect to the frame). Other locations include: head tube (front of frame where handlebars connect), rear dropouts (where the rear wheel attaches), or on a sticker on the seat tube. Serial numbers are usually 6-12 characters of letters and numbers.

Can I check e-bike serial numbers?

Yes! E-bikes often have multiple serial numbers - one on the frame, one on the motor, and one on the battery. We recommend checking the frame serial number first, as this is what's typically registered in theft databases.

What brands of bikes can I verify?

Our verification works for all bicycle brands including Trek, Specialized, Giant, Cannondale, Santa Cruz, Yeti, Scott, Canyon, Cervelo, Pinarello, BMC, and all other manufacturers. Any bike with a serial number can be checked.

How do I know if a bike serial number is legit?

Legitimate serial numbers are stamped or engraved (not stickers). They should be on the frame, not components. Be wary if the serial number area appears scratched, filed, or covered. Some thieves attempt to remove or alter serial numbers.

What if the bike has no serial number?

This is a major red flag. All major manufacturers stamp serial numbers on their frames. A missing serial number could mean it was removed to hide the bike's stolen status. We recommend not purchasing bikes without serial numbers.

What databases does SafeOrStolen check for bikes?

We search Bike Index (the largest stolen bike database with 500,000+ bikes registered), 529 Garage, local and national police databases, insurance claim records, and manufacturer registries. This comprehensive search gives you the best protection.

What if the bike is reported stolen?

Do NOT purchase the bicycle. Walk away immediately. You can report the listing to Bike Index and the marketplace. Consider notifying local police. The original owner may be actively looking for their bike.

Should I register my own bike?

Yes! Register your bike on Bike Index (it's free) and record your serial number. If your bike is stolen, registration dramatically increases recovery chances. Many police departments check Bike Index when they recover stolen bikes.

What is Bicycle Serial Number Verification?

Every bicycle has a unique serial number stamped by the manufacturer, usually on the bottom bracket (where the pedal cranks meet). When a bike is reported stolen, this serial number is logged in databases like Bike Index, 529 Garage, police records, and insurance claims. Our verification service searches these databases to check if a bicycle has been reported stolen. This is especially critical for expensive bikes - high-end road bikes, mountain bikes, and e-bikes that can cost $2,000-$10,000+.

Why Check Before Buying a Used Bike?

Bicycle theft is epidemic in America - a bike is stolen every 30 seconds. Only about 5% of stolen bikes are ever recovered, making the used market a prime destination for stolen property. Here's why verification is essential:

2 million bikes are stolen every year in the US alone

High-end bikes (Trek, Specialized, Giant, Cannondale) are prime targets

E-bikes are increasingly targeted due to their $2,000-$10,000 value

Police regularly check serial numbers and will confiscate stolen bikes

Possession of stolen property is a criminal offense

No warranty or insurance coverage for stolen bicycles

Bike Index and 529 Garage actively track and recover stolen bikes

You have zero legal recourse if you unknowingly buy stolen property

Common Use Cases

Road Bike Purchases

Carbon road bikes from brands like Trek Madone, Specialized Tarmac, and Cervelo are theft targets. Always verify.

E-Bike Verification

Electric bikes are expensive and easy to steal. Verify the serial number on both the frame and motor.

Mountain Bike Buyers

High-end mountain bikes are frequently stolen from trailheads. Verify before buying used.

"Almost bought a 'barely used' Specialized Turbo Levo e-bike for $2,000 on Craigslist. SafeOrStolen flagged it as stolen in Portland. The seller ghosted when I asked about it."
