This bicycle lock did its job. Someone tried to pry it off, or maybe they used a car jack, but it held on. Unfortunately the owner still had to pay me to remove the bicycle lock since the key didn’t work it anymore. If a smaller U lock was used, it would be harder to get a car jack into the lock. Not all bicycle locks are made of the same quality. The Abus bicycle locks are superb and take a longer time even with my angle grinder, though the Bordo locks won’t stand up to bolt cutters or angle grinders and shouldn’t be used for locking a bicycle in a high crime area overnight.
