The Serea Bolt ART 2 bicycle lock is a modern and reliable chain lock that combines high theft protection with optimal ease of use. Thanks to the ART 2 quality mark, this lock meets the requirements of most bicycle insurers and is suitable for daily use in urban environments. The strong hardened steel chain provides solid protection against cutting and forcing, while the generous length ensures you can easily secure your bike to fixed objects such as posts or bike racks. What sets the Serea Bolt apart is its keyless operation. The lock works via NFC technology and is opened with your smartphone, so you no longer need a physical key. Because the lock does not have its own battery, you never have to worry about charging or empty batteries. In addition, you can share digital access with others, making this lock ideal for shared use within the family or at work. A smart and safe solution for those who want to combine comfort and security.
