Kryptonite SBX Retractable Frame Lock, ART2 SSF Certified

Kryptonite is a leading brand in the world of bike and motorcycle locks. It offers this model, common to many city bikes, but with a build quality far superior to most of its competitors.

Its simple yet effective mechanism secures a bike by locking the rear wheel. Once locked, it is impossible to turn the wheel, meaning the bike must be carried to move it.

This version features the "Key Retaining" option, which locks the key in the lock when it is in the unlocked position. This feature is handy for preventing the key from being lost and ensures it is always in place for quick bike security.
