The FS 580 is our strongest folding lock in the series. The special highlight, however, is the back of the bracket: here, an Apple AirTag or a Samsung SmartTag can be hidden inconspicuously and securely. With the tags, the bike can be tracked via smartphone with minimal effort. The rubberized links made of hardened steel can be unfolded up to 90 cm in length. Locking a bike to a stationary object is very easy. For convenient locking, the lock is equipped with a 360 degree rotatable insertion area on the lock head and a reversible key. The IN-X® cylinder is protected from dust and dirt by a cover. The 90 cm version comes with the new X-PRESS bracket. The locking mechanism of the X-PRESS holder makes it even easier to remove and insert the lock. To remove the lock, press the red button and the lock is released. To secure the lock in the bracket again, simply press the brackets together.
