Guard Dog 8020 Bike Lock
Bosnianbill (youtube) tested the 8021 model. The 8021 and the 8020 differ in chain length but have the same lock and component specifications. The lock cannot be picked. The chain defeats bolt cutters (48 inch levers) and hack saws. A portable grinder will cut it but it took 1 1/2 4 inch cutter wheels. For my use that's pretty good. It is heavy and the weight has been reported as 4 to 10 pounds. I don't have a scale in that range so can't give an accurate value. I would suggest carrying it in a triangle frame bag or use as a destination lock.
