Researcher: Lime's Public Bike Data May Reveal Your Rental Route

A researcher says Lime's public bike availability feed lets anyone link persistent vehicle IDs across trips to approximate trip origins and destinations. The GBFS standard requires operators to randomize vehicle IDs after each trip, but Lime's implementation reportedly does not. Combining feed snapshots with maps or public records can expose sensitive location patterns.

• Lime's feed shows a bike's location, status and ID before rental
• Bikes vanish from the feed during trips and reappear elsewhere after
• GBFS requires randomizing vehicle IDs after each completed trip
• A 2026 study reconstructed over 80% of trips in two cities
