What is the difference between a chain lock and a cable lock?

The main differences lie in structure and performance. Chain locks use interlinked metal links (often hardened steel), offering superior strength and resistance to cutting tools—ideal for high-risk areas or valuable items like motorcycles. However, they’re heavy, bulky, and lack flexibility. Cable locks, made of braided steel strands, are lightweight, flexible, and easy to carry. They wrap around tight spaces or irregular objects (e.g., bike frames, laptop bags) but are less durable against heavy-duty cutters. Use chain locks for long-term, high-security needs (e.g., overnight bike storage) and cable locks for portability and low-to-medium risk situations (e.g., quick stops at stores).
