Experts say no bike lock is impenetrable, so the test of a good lock is how long it can resist attacks. In reviews, testers easily clipped most cable locks in a few seconds, so they do not recommend relying on a cable lock alone. Steel U-locks are top-rated overall, but research shows they typically fit around the frame, one wheel and the bike rack, leaving the other wheel and the seat unprotected. One solution is the OnGuard Bulldog DT 5012 bike lock, which includes a U-lock made of hardened steel and a supplemental cable together in one package for a reasonable price. If your bike is valuable or gets left in a high-crime area, however, experts say you should consider buying a maximum security U-lock, such as the Kryptonite New York Fahgettaboudit U-lock (*Est. $75) for the frame and rear wheel, and a second U-lock for the front wheel.
The New York Times and Amazon.com have the best reviews of the OnGuard Bulldog DT 5012 bike lock. They focus on usability, and do not include tests or comparisons with similar locks. Two online sources, BikeRadar.com from the U.K. and Consumer.org.nz from New Zealand, comment on the OnGuard Bulldog's endurance under hand-tool attacks, but do not specify which Bulldog they tested.

Without focusing specifically on the OnGuard Bulldog DT 5012, this online U.K. source mentions that the OnGuard Bulldog, OnGuard Pitbull and OnGuard Brute all performed "admirably" in their first round of tests with hand tools.

This New Zealand magazine tests and rates six cable locks and five U-locks. The OnGuard Bulldog STD 5012 is one of the best U-locks they test, resisting attacks with hacksaws, bolt cutters, lock picks and brute force for more than a minute.
