With this bicycle lock, you can connect your bicycle conveniently, easily and quickly to a fixed object. You do not even need a key, as the Booster 670 Spiral Cable Lock engages directly thanks to the special ABUS automatic locking technology. In addition, the ABUS automatic cylinder is equipped with a drilling protection, which makes the drilling into and drilling open of the lock considerably more difficult for potential thieves. If the Booster 670 Spiral Cable Lock is not required, it can be conveniently transported on a special holder on the seat post.
