OnGuard Bulldog Mini U-Lock
Having a tough time getting that lock shackle through the front wheel, the frame and then around whatever hopefully solid object you're locking everything to? Then check out the OnGuard Bulldog Mini U-Lock bike lock. It has all the security features you come to expect from OnGuard, but the shackle is a little longer, making it easier to lock it up to almost anything in sight. Plus, with the additional length it fits in your belt a little better if you don't feel like using the included mounting bracket.
  • X2 Power Double Locking Mechanism provides superior protection against pry attacks
  • High quality lock cores ensure that the shackle can't be pried out of the lock cylinder
  • Unique cylinder design offers optimum resistance against picking
  • Entered keyway helps protect against drill attacks
  • Protective sleeve over crossbar helps limit access to lock's internal workings
  • 13mm ultra-hardened steel shackle provides maximum cut resistance
  • 5 unique lock keys included (1 with LED light)
  • $2,251 anti-theft protection offer though onguard

    Comments about OnGuard Bulldog Mini U-Lock:

    I have used many locks in the 30+ years I have been on two wheels...this is a standard U lock. It came with many keys like 5 or 6, one with a light. The keys are laser cut not the round keys that a Bic pen can crack open. It also came with a lock holder, though I am not too confident it will stand up to repeated use, though time could prove me wrong. In all happy with the price/quality etc.
