Union is a bicycle lock that is integrated into the seat post of a bicycle. The lock offers three functions: fingerprint unlocking, magnetic fixing and reflective warning. Fingerprint recognition removes the need for keys and makes daily use faster. A magnet inside the lock body holds the lock against the seat tube during riding. A chain is stored inside the tube and is pulled out to secure the wheels to a fixed object. The size is 28 by 74 by 352 millimeters, which matches a standard seat post, so the frame stays clean and storage problems are avoided.
