This compact powerhouse packs 0.51 inches of hardened steel to keep your bike exactly where you parked it. It sports a prestigious Sold Secure Gold rating, meaning it’s basically a "keep out" sign for any would-be thieves. The included USH bracket lets you snap it onto your frame for easy transport without the clanking. Small enough to toss in a bag but tough enough to make bike snatchers cry, it's the ultimate urban sidekick.
