What sets the KryptoFlex 525 apart
The KryptoFlex 525 combines a slim, flexible cable design with Kryptonite's proven key-lock security. Unlike rigid U-locks, the cable adapts to different frame shapes and wheel sizes, making it versatile for city bikes, hybrids, and commuters who need a quick, lightweight locking solution.
Ideal for...
Urban commuters and casual riders who need a dependable, lightweight lock for short stops at cafes, offices, or bike racks. The compact 76 cm cable is well suited for bikes with standard frame geometry where a full-length cable is needed without the bulk of a longer lock.

Thread the cable through the frame triangle and around a fixed anchor point such as a bike rack or pole

Remove the key and store it in a safe place; the lock is ready for your next ride
