Designed to protect an electric bike, the K-Traz M18 is an extremely strong chain with reinforced steel links and an integrated key lock. With a security level of 18/20 and a 10mm-thick hexagonal link, this lock is ideal to protect your bike in very high-risk areas. Its 1.10m length makes it easy to lock your bike to street furniture. The chain lock system is a small 14mm diameter U-shaped lock which is itself very resistant to shocks and torsion.
