Hardened Steel – A Must-Have for Protection The most critical security feature of any chain lock is the strength of the chain. Effective theft protection begins with a chain thickness of at least 7.5mm, which can deter even professional thieves. In general, the rule is: more mass equals more security. However, greater chain thickness also means added weight, making some heavy-duty locks less practical for everyday use. The KOHLBURG Gothenburg lock strikes an ideal balance, with its massive 8mm square chain providing excellent security, without sacrificing usability. To defend against bolt cutters and metal saws, the hardness of the steel is crucial. Unlike many cheaper imports, the chain links of this KOHLBURG lock are made from hardened special steel – and this is proofed by Sold Secure with the GOLD security status. Additionally, the square shape of the chain makes it even more resistant to bolt cutters by increasing the surface area that needs to be cut compared to round chain links. Finally, a Secure Combination Lock This lock features a robust combination mechanism that offers high protection against lock-picking (unauthorized opening with specialized tools). The dials of the combination lock are made from stainless steel and housed in a metal casing. This construction allows the lock to withstand hammer attacks and is also weather-resistant. The security of this combination lock far exceeds that of many other locks that use cheap plastic components for their interiors and dials – a weakness that thieves can easily exploit. Not so with the KOHLBURG Gothenburg lock. High Flexibility with a Manageable Weight The longer a lock is, the easier it is to secure your bike to a fixed object. The KOHLBURG Gothenburg lock offers a generous 43 inches of chain length, allowing you to lock your bike without much hassle, even around wide objects like streetlights or trees. This length, combined with the chain’s thickness, results in a total weight of 5.1 lbs. Please ensure that this weight is acceptable for your needs before purchasing.
