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 Medium 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.

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
