Kryptonite Evolution

The 14mm hardened steel shackle is specifically engineered to resist bolt cutters and leverage attacks. While no lock is entirely invincible against heavy-duty power tools, this thickness provides a significant deterrent that forces thieves to spend considerably more time and effort, usually causing them to move on to an easier target.

The lock includes a FlexFrame-U bracket, which is designed to attach to most bike frames for convenient transport. Since the lock weighs 3.5 lbs, using the bracket is the most secure and balanced way to carry it, keeping the weight centered rather than bouncing around in a bag.

The double deadbolt design locks both sides of the shackle into the crossbar. This is a crucial security feature because it prevents 'twist attacks,' where a thief tries to pry the lock open by twisting the shackle to break only one side of the locking mechanism.

Yes, the integrated LED light on one of the three included keys is surprisingly practical. It illuminates the keyhole, which saves you from fumbling with your lock in low-light conditions or dark parking areas at night.

Yes, the lock is weather-resistant and designed for year-round outdoor use. The disc-style cylinder is built to resist the elements, though it is always good practice to occasionally lubricate the mechanism if you live in a particularly harsh or salty environment.

This 'Standard' size is a versatile middle ground. It is compact enough to carry easily but large enough to secure your frame and one wheel to most standard bike racks, poles, or railings.
