Your bike page, as a certificate

A published bike page can now double as a maintenance certificate for a buyer — the thing you send someone instead of saying "yes, it's been serviced".

• Switch it on per bike with Show as certificate. It's off by default and it's yours to enable; nothing becomes public that wasn't already.

• The Certified badge only appears when the record backs it up. Four rules: the bike page is published, mileage comes from Strava, at least one component has an install date, and at least one service is logged. Miss one and the page shows the plain profile, with a link to fix what's missing.

• When it passes, the page reads Certified · mileage from Strava since [date] · [n] services logged, and the seal is stamped on the hero photo.

• There's a print stylesheet, so it prints as a clean document rather than a screenshot of a web page.

• Certified bikes carry the badge through to your public profile.
