The locks measure roughly 33.5 inches in circumference, allowing flexible use to secure your bike to various objects. They are also waterproof, corrosion-resistant, and built to withstand impact and drilling attempts.

While folding locks generally offer less length than cable or chain locks, which might limit locking options in some environments, this set strikes a balance of strong protection, convenience, and style.

The lock opens up to a 33.5-inch circumference, suitable for locking to various racks and posts. However, it’s not a cable or chain lock, so flexibility around irregular objects is somewhat limited.
