Tough on the inside, soft on the outside. The 14mm Alloy Steel Shackle provides robust resistance against bolt cutters and leverage attacks.

  • Anti-Scratch: The entire lock body and shackle are wrapped in a thick silicone cover, ensuring it never scratches or chips your bike's paintwork while riding or parking.
  • Heavy Duty: Built for urban security with a solid, impact-resistant design.
Feature 2

130dB Active Alarm & Weatherproof

A lock that screams.

  • 130dB Siren: A sensitive shock sensor triggers a loud 130dB alarm if the lock is bumped or tampered with, acting as a powerful deterrent.
  • IP67 Rated: Fully waterproof electronics allow you to park outdoors in rain or shine without worry.
