This comprehensive guide reviews the most secure bike locks, including U-locks, heavy-duty chains, folding options, and innovative angle grinder-resistant models. We've drawn from lab tests by Bikerumor (13 locks), BikeRadar (12 locks), Guardian (15 US locks), and others to rank them by security ratings, cutting resistance, weight, and value.
Quick answers to top questions:
- Toughest overall: Litelok X3 (8 min grinder resistance, Sold Secure Diamond).
