The toughest ABUS folding lock on the market is now even more robust: The latest generation of advanced bike locks combines the proven, intelligent alarm system with an advanced locking mechanism.The BORDO GRANIT™ 6500KA secures your bike in the best possible way: with a sensitive alarm system, strong steel bars and built-in XPlus precision disc cylinder.The folding lock doesn’t have the high ABUS security level 15 for nothing. The 5.5 mm bars of specially hardened steel are connected with special rivets. The ABUS Link Protecion Shield ensures that these rivets serve as a robust protective shield against sawing attacks. They also make the lock more flexible. The ABUS XPlus cylinder boosts security with the highest possible protection against manipulation attempts, e.g. picking.The BORDO™ 6500KA is also an alarm lock that triggers a 100 dB loud warning tone in the event of movement. But thanks to the intelligent ABUS alarm system, your neighbours will no longer despair of constant false alarms. The full alarm is only activated in the event of a suspected attack - accidental knocks and movements, on the other hand, only trigger a short, 5-second warning.
