10 Best Bike Cable Locks 2025 in the United States

The Master Lock Cable Lock, 8122D, is a versatile and practical option for securing bicycles and other outdoor equipment. With a 6 ft. long cable and a thickness of 5/16 in., it provides a decent level of security while maintaining flexibility. The cable is made from braided steel, which offers strong resistance to cutting, and it's coated with vinyl to prevent scratches and rust, enhancing the durability and longevity of the lock.

The adjustable locking mechanism is a standout feature, allowing the user to set the cable length precisely to secure a wide range of items. This flexibility is complemented by the ease of use of the 4-dial combination lock, which eliminates the need for keys and allows for a personalized code. However, it is worth noting that the 1/2 in. diameter may not be as robust as thicker options on the market, potentially making it less secure against more determined theft attempts. Additionally, while the vinyl coating is beneficial for weather resistance, the lock might not withstand extreme weather conditions over prolonged periods. Portability is another highlight, as the lock is lightweight and compact, making it easy to carry around. This makes the Master Lock Cable Lock, 8122D, well-suited for users looking for a balance of security, convenience, and flexibility for everyday outdoor use.

A nice extra is the carrier bracket, making it easier to transport the lock on your bike.

Weighing nearly 3 pounds, the lock’s weight contributes to its durability and is common for strong U-locks.
