Learn about Kryptonite’s WheelBoltz and see a step by step guide on how they install on your bike. WheelBoltz are for hollow axles only and replace your wheel’s quick release. They are great to use for secondary security on your front and/or rear wheel.
When the bike is upright, the WheelBoltz are locked and can only be unlocked with the bike turned upside down. A primary U-Lock or chain prevents the bike from flipping when secure to a fixed object.
Easy to install/uninstall with 5mm hex wrench that is included.
Front wheel – 130mm
Rear Wheel – 150mm
