Frequently Asked Questions (FAQs)

1. What is better chain lock or U lock?

For stationary security (usually at home or at work), then a thick, heavy chain is better than any u-lock. They are more secure and much better suited to a home environment where you are unlikely to have a handy bike rack to slip your u-lock round and may want to secure several bikes at once.

2. Is there a bike lock that can't be broken?

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.
