Frequently Asked Questions (FAQs)

1. Are there any bike locks that Cannot be 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. How thick should a bike lock be?

And if you want to be absolutely sure your bike lock can't be defeated by bolt cutters, you normally need a chain or a u-lock shackle that is at least 16 mm thick. Because at 16 mm, good quality, properly hardened steel is too thick to be cropped by any manual bolt cutters.
