May I suggest you carry two of these
https://www.mcmaster.com/8942T14 3/8"x6' stainless wire rope slings for securing the bike to power poles, gas meters, live electrical conduits. Stainless wire rope is a PIT* to cut, usually requires 2 hands to hold it against the battery grinder in a 3rd hand. Or the thief can cut one wire at a time with a diagonal cutter, which takes about 45 minutes. 6' length which I use will do those tethers, 8' would wrap most light poles in parking lots. One sling for frame, one for wheel with hub motor if your model has one. Weigh much less than serious alloy 3/8" chain. Fit in a large pannier for each. Plus two Abus 92/80 locks (ebay zoro), or Abus granite if the hasp opening will fit two sling eyes. Plus sabre pepper spray mounted to the handlebar with a Kale tie. Plus a NIJ class IIIa kevlar vest (skarrarmor.com, ebay or direct) to restrict knife and pistol attacks. I use all those downtown Kentuckiana, particularly in grocery stores. I have a white one which i wear under a colored dress shirt, which makes it invisible. I haven't used the pepper spray against humans, but have warded off packs of dogs in the country at stop signs.
