Overview
How Does the KryptoFlex 1018 Cable Lock Secure Your Bike?
The Kryptonite KryptoFlex 1018 Cable Lock pairs a 10mm braided steel cable with a four-digit combination lock for quick, keyless security on rides where flexibility matters. At six feet long, the cable gives you enough reach to loop through both wheels and a fixed object, making it a practical everyday carry for café stops, group rides, or any situation where you need a fast, lightweight lock. The combination reset feature lets you set a code you will actually remember.
The looped cable design handles awkward rack shapes and tight spaces better than a rigid U-lock, and the vinyl protective coating guards your frame finish from scratches during use. This is an ideal secondary lock for cyclists who already run a U-lock or chain as their primary, filling that role perfectly for wheel security or quick low-risk stops. It stores easily in a jersey pocket or saddle bag so it is always there when you need it.

FAQ
Good questions
Get to know Kryptonite

There's more to Kryptonite than this one product. Our Kryptonite page has the full Kryptonite lineup we carry and more about the brand.
Visit the Kryptonite page →Is the KryptoFlex 1018 suitable as a standalone lock?
It works well for low-risk stops and casual use, but Kryptonite recommends pairing it with a U-lock or chain for higher-risk parking situations where cut resistance matters most.
How do I reset the combination on the KryptoFlex 1018?
Open the lock with the current code, hold the shackle in the open position and turn it to the reset angle, set your new four-digit code, then release the shackle to lock in the new combination.
Will the KryptoFlex 1018 fit in a jersey pocket?
Yes, the coiled cable and lock body are compact enough to fit in a standard jersey back pocket or saddle bag, making it a practical carry for road and gravel rides.
