The highest-rated U-locks, chain locks and folding locks we’ve tested
If you are looking for the best bike lock, it can be easy to fall into a rabbit hole of never-ending research. Instead, I’ve done that for you. I spent months interviewing representatives from leading lock companies and polling thousands of cyclists. I found that the number of people who had a quality lock defeated was small.
Not everyone’s lock requirements are the same, so we’ve looked for the best bike lock we could find to cover a wide range of different use scenarios. Sold Secure is an independent, UK-based organisation which tests a wide range of bike locks, rating them from Diamond, through Gold, Silver and Bronze.
To avoid having your bike stolen, choosing the best D-lock you can is a worthwhile investment and we have included Diamond and Gold-rated options along with the best budget bike locks too. We also highlight some great chain locks if you’re looking for a bit more locking flexibility and some lightweight bike locks that are easier to transport.
