Cable Locks: While cable locks are lightweight and easy to use, they are best suited for lower-risk areas as they can be cut more easily than other lock types. They are ideal for quick stops or when a bicycle is secured in a relatively safe environment.

Smart Locks: Smart locks bring the convenience of technology into bike security, allowing users to unlock their bicycles via smartphone apps. While they offer innovative features like tracking and alerts, they also require batteries and can be more costly than traditional locks.
