Frequently Asked Questions (FAQs)

1. How thick should a bike chain 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.

2. Are chain locks any good?

Chain locks work better with ground anchors than D locks do. This is thanks to their greater length and size. A larger locking area can be a good advantage when securing your bike at home, as you'll be able to secure more than one bike at a time.
