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.

- Daytime parking in a high theft risk area (high traffic areas, dense residential areas,...) and in a moderate theft risk area (medium-sized cities, university campus,...)
- Overnight parking in an area with a low risk of theft (residential areas, low density...)
- Attached to a bike rack on a car all day (make sure the bike rack is equipped with an anti-theft device)
This lock has a very high level of security but is heavier and bulkier than other models. This will make it less easy to transport, but it will fit well on an e-bike.
Your lock will be exposed to the weather, as moisture and dust as well as cold can affect its function. Care and cleaning of a lock will extend its life and keep it functioning properly.
