Frame locks like the Amparo 4750S are primarily designed for quick stops or as an immobilizer to prevent someone from riding away with your bike. For high-risk areas or long-term parking, we recommend pairing this with a secondary chain or U-lock to secure your bike to a fixed object.

Yes, the case, shackle, and internal locking elements are all constructed from special hardened steel. This provides a robust level of protection against basic tampering and ensures the mechanism holds up well in various weather conditions.
