In the last year, I have tested over a dozen of the best bike locks, including five of the most angle grinder-resistant. However, this compact little number from OnGuard won me over, and let me tell you why.
Most importantly, the OnGuard Pitbull Mini is a Sold Secure Cycle Diamond-rated bike lock, which means it's highly resistant to attacks from various tools, such as bolt cutters. You might wonder why I chose not to go for one of the brilliant and nearly impenetrably angle grinder-resistant ones I tested.
