TRELOCK protection - reliability and quality. The number of bicycle thefts is not decreasing, and only one in ten stolen bikes eventually returns to its owner. However, you can reduce the risk of theft by investing in a sufficiently secure lock. TRELOCK offers locks of various security levels to suit everyone's needs. The higher the security level, the harder it is for thieves to defeat. Innovative security and design solutions build confidence in the TRELOCK brand. Modern lock core manufacturing technologies and high-quality materials deliver greater security and lower weight.
The BC 580 is a high-security chain-type lock. Its 110 cm length is enough to easily secure a bike in most situations, while the quality disc-type core and 9 mm chain link thickness significantly reduce the chance that thieves will make off with your bike. The lock is protected against corrosion and the core against dust. Suitable for electric bikes too.
