Frequently Asked Questions (FAQs)

1. What bike locks Cannot cut?

Is There a Bike Lock That Can't Be Cut? The Altor SAF and the Skunklock are the two most uncuttable bike locks on the market. Both of these locks employ anti-cut features that make them capable of defeating power tools. These two locks are the strongest and most unbreakable bike locks on the market.

2. Can Kryptonite locks be cut?

Kryptonite New-U KryptoLok Standard: This U-lock employs a disc-detainer mechanism, like the New-U Evolution does, and it now comes with the same double-deadlock design as our top pick. (The version we tested did not.) However, the biggest problem with this lock hasn't changed: Bolt cutters can cut through it.
