Silicone-Coated, Compact U-Lock

SIDEKICK is a NEW addition to the OTTOLOCK family, designed for preventing bike theft by itself or together with a cinch lock for added security.

SIDEKICK weighs just 1.65lbs! For maximum bike security, use together with an OTTOLOCK cinch lock.

  • STRONG: Tough, durable design. Double shackle 12mm hardened steel with anti-rotation deadbolt (shackle diameter 16mm with silicone). Use cinch lock for quick stop security and protecting against opportunity theft.
  • KEYED: Two keys included with Sidekick. Cinch lock is combination. OTTOLOCK cinch lock is not a replacement for a U-Lock. Double up for added security. See use guidelines.
