Your Perfect Companion For Bike Security

The Ottolock Sidekick XL is a superlight & keyed U bike lock with a double shackle, silicone-coated design so you won't scratch your paint. The XL is an all-new deeper reach model allowing you to grab a wheel together with bike frame and post.

Designed for preventing bike theft by itself or together with a cinch lock for added security, the Sidekick is set apart from other U-locks by its compact silicone-coated form factor and lightweight size, making it easy to stow in a backpack. The SIDEKICK XL weighs 2.50 lbs.and allows for deeper reach and more security options compared to the original Sidekick.


  • COMPACT: Fits easy in bag or pack. Opening is 4.00" x 9.50" (10cm x 24cm)
  • NON-MARRING: Silicone-coated lock body. Won't scratch your bike frame.
  • STRONG: Double-shackle 14mm hardened steel with anti-rotation deadbolt.
