Is the PitBull U-Lock Worth It for Serious Security?

The OnGuard PitBull Series U-Lock steps up the security game with 8.4 tons of pull strength and a higher-quality lock core that resists picking and drilling better than entry-level options. Built for cyclists who park in high-theft urban environments, the PitBull is engineered to outlast and outwit the most common attack methods. The hardened steel shackle at 4.5 x 9 inches hits the sweet spot between coverage and portability.

The PitBull comes keyed with multiple keys included, making it a reliable daily workhorse for commuters who want no-fuss security. The 4.5 x 9 inch interior dimensions work well for locking a frame and wheel to most standard racks and street posts. If you're investing in a quality bike and parking in urban areas regularly, the PitBull is the OnGuard model to reach for.
