How Do I Prove I Own My Bike?
It's a question most people never think about — until their bike is stolen, recovered, or they're selling it and the buyer asks. Proving a bike is yours comes down to three things: the frame number, the paperwork, and a record that ties them to you. Here's how to have all three ready.
The frame number is everything
It's your bike's unique fingerprint — usually stamped under the bottom bracket, on the head tube, or a dropout. Find it, photograph it, and record it today.
1. Record the frame number
Turn the bike over and look under the bottom bracket (where the pedals meet the frame). Note the number exactly, and take a close photo. This single detail is what lets police match a recovered bike to you.
2. Keep the paperwork
Your original receipt or proof of purchase is the strongest single document. Keep receipts for upgrades too — a photo of each is fine. If you bought second-hand, keep the seller's details and a dated receipt.
3. Tie it together with a registration
Registering your bike puts the frame number, photos and your details in one dated record. If ownership is ever questioned, that record shows the bike was linked to you from a specific date — powerful when the alternative is someone's word.
Do it before you need it. Five minutes now saves a hopeless scramble for details later.
