I'm the same height/inseam and have two 16 Radrovers. I was getting sight ache in my left knee and numb hands on longer rides with the out of box set-up (no adjustable handlebar stem and 350mm seatpost). I added the Sunlite 0-60 degree Adjustable handle bar stem, 420mm Bodyfloat suspension seatpost, and Cloud-9 11.5X12.5 cruiser seat to my Rover to fit my body. I also added Wide Platform MTB pedals by BC Bicycle company for my size 14 shoes. It has been +4 years and +7000 miles and I can ride until the battery dies without issue.
You are going to be a little under 7 feet tall sitting upright in the saddle with a helmet. It will be a long ways down on spills and a lot of ducking with low branches with trial riding.
