I installed some rubber bumpers around the padlock in an effort to keep it nice and shiny and protect it from dings and scratches, and I mated it to an Abus 8KS110 chain of similar thickness - and presumably strength:
Here I’m trying it on my folding bike:
I reckon it makes a decently convincing bike chain. Possibly even moped or motorcycle chain, provided it’s not a very desirable machine and you don’t park it in the slums.
One thing that concerns me is that the padlock looks unusual enough to attract nogoodniks in its own right. And as we know, the key to bike security is unobtrusiveness. This padlock definitely ain’t discreet.
The other thing that concerns me is that the bike and the padlock left in the street are half again the cost of the bike alone
