I ride a rad mini and a Rad city step thru, I weight 326lbs and carry a few things in panniers on my racks and an occassional small cooler on the front mini rack
I get about 30mi range on #2 setting using #3 for hills on both bikes that's mostly paved and hard gravel paths . I keep spokes tight and air pressure up.
I don't jump curves and go easy on pot holes and large bumps 2years plus and so far so good. May acquire 2nd battery's for longer rides. my mini and city use different batteries.
Wish they were the same. May buy a third bike to offset the battery cost.  Maybe a rad rover
