TRELOCK Protection - Reliability and quality. Bicycle theft numbers are not decreasing, and only about one in ten stolen bicycles is ever returned to its owner. However, the risk of theft can be reduced by investing in a sufficiently secure lock. TRELOCK offers locks with various security levels to suit every need. The higher the security level, the harder it is for thieves to defeat the lock. Innovative security and design solutions are what build trust in the TRELOCK brand. Modern lock core manufacturing technology and high-quality materials result in greater security and lower weight. The compact TRELOCK U4 Mini lock model provides a medium security level thanks to its hard-to-break parabola shape and a quality disc core protected from dust by a cover. The lock has additional protective measures at the most vulnerable points, which thieves usually target. The 14 mm diameter shackle is made from special hardened steel, making it highly resistant to cutting, sawing, bending, and impacts.
