OnGuard Brute STD U-Lock

Reid Price $49.99



The best protection for high crime areas, the OnGuard Brute series is the ultimate protection against bike thieves.

  • Massive 16.8mm hardened steel shackle (11.1cm x 26cm)
  • 4XP Quattro Bolt Locking Mechanism locks shackle on four sides
  • Includes a snap lock quick release mounting bracket for easy transportation
  • Includes 5 laser cut keys (1 micro-light with bright white beam and 4 extra-grip keys)

Bike thieves are the worst! Deter them with this ultimate security lock, which is still compact enough to carry. The 16.8mm hardened steel TriRadius shackle resists all forms of cutting, prying or jacking, and provides extra room for more locking options. This makes it great for locking your frame to a bike rack or railing, even when you are parked up in a dodgier area.

The double rubber coated crossbar cover protects the finish on your bike, and the extra thick molded end caps protect against bumps and hits on the frame to keep your bike looking good. An automatic keyway cover helps to seal the lock internals against the elements.

We recommend carrying one key with you and leaving one at home or with a friend, just in case you lose your keys. It's a tough lock to remove if you don't have the key!
