Wheel-Locking Wheel Nuts

The Kryoptonite Security WheelNutz can only be removed when the bike is turned upside down, bringing an extra level of protection to urban bikers.

Developed with city bikers in mind, the Security WheelNutz were created to secure the front wheel of the bike without the biker needing to carry an extra lock. The WheelNutz fit on the axle of the front wheel, replacing the existing nuts, and can only be released when the bike is upside down—something that is nearly impossible to do when the bike is locked to a sturdy object.
