"Locked it, heard the beep, walked away. First time in years I didn't look back twice at my bike."
"The alarm went off when a shopping cart hit my wheel. Loud enough to make me jump from 30 feet away."
“USB-C is what sold me. I can charge it with the rest of my gear instead of relying on replacement batteries.”
Your bike only has to look easy once.
BikerZoneZ Guardian Lock secures directly through your brake disc with a solid 7mm locking pin and a tough alloy body built to resist prying, impact, and cutting attempts.
