529 Detective scans Craigslist, Facebook Marketplace, eBay, OfferUp, Kijiji, and Pinkbike twice daily, surfacing new listings similar to your bike.

You register your stolen bike. Detective does the rest.
Add your bike's details, photos, and serial number. This creates the profile Detective uses to scan. Takes about 5 minutes.
Detective scans Craigslist, Facebook Marketplace, eBay, OfferUp, Kijiji, and Pinkbike twice daily so you don't have to. New matches land in a daily digest email.
Detective sends you listings that could be your bike. You review them in one place, much easier than sifting through thousands of listings across 6 sites yourself.
Use the match evidence to work with law enforcement. Your 529 registration has the details (serial number, photos, description) that police need to help.
All 6 online marketplaces scanned twice daily. New matches land in a daily digest email.
Some stolen bikes are listed within hours. Others take months to surface. Detective scans six marketplaces, twice a day, for six months.
New photos, different city, parts swapped. Detective's matching goes beyond exact text. It compares visual and structural characteristics.
Manually checking Craigslist, Facebook Marketplace, eBay, OfferUp, Kijiji, and Pinkbike every day across multiple cities is unsustainable. Detective does it for you, automatically.
A matched listing + your 529 registration gives police the details they need: serial number, photos, and a record of your bike. Detective helps you build that case.
