Gone.Bike is an open-source project aiming to create a global, publicly accessible database of stolen bicycles. Users can report stolen bikes, search for suspicious bikes (e.g., when buying second-hand), and use image search and dynamic filters to match bikes. The platform aggregates reports from individuals and public sources, and plans to add features like threaded discussions and a theft heatmap. Police can use the database to identify owners when recovering bikes. The project is motivated by the emotional and practical impact of bike theft, aiming to empower cyclists and authorities with technology to fight theft more effectively. The platform uses modern web and database technologies and is designed for community collaboration and transparency[1][2].
