ROCKBROS Folding Bike Lock

The lock comes with a default code, typically 0000. To reset it, open the lock, rotate the reset dial inside the lock head as indicated in the manual, set your new combination, and rotate the dial back to the locked position.

No, the lock segments are wrapped in a durable ABS plastic coating. This smooth exterior is designed specifically to prevent metal-on-metal contact and protect your bike's paint finish while you secure it.

The included bracket is designed to fit most standard bicycle frames using the provided straps or mounting bolts. However, if your bike has an unusually thick or uniquely shaped frame, you may need to find an alternative mounting location or carry the lock in a bag.

At 33.5 inches, this lock offers a generous reach that is suitable for standard bike racks and most street poles. It is generally long enough to secure the frame and one wheel, though it may be tight if you are trying to lock around very wide objects.

This folding lock provides a high level of security due to its zinc alloy and steel construction, making it very resistant to cutting attacks. While U-locks are often considered the gold standard for maximum security, this folding design offers a comparable balance of strength and significantly better portability.
