@ascentale @bikenite A1: Sydney, Oz. today's three hour round trip was picking up a pile of second hand plastic drums to store food in (I buy wholesale rice a year at a time because it's half the price)
The drums are empty so it's under 100kg, they're just bulky (there's also one in the bin on the bike)
My mistake was not taking the battery powered infrastructure improvement apparatus, I got blocked a couple of times by anti-bicycle barriers on bike paths.
