I read through court's review. I don't see anything major wrong with it. Nuvinci 360 drive is okay except in extreme hills. 11.5 AH battery give as they say 35 mile range minimum, that may be fine for you. 28" tire tubes are not sold in my grocery store, you'd have to get them on line or maybe at a very serious bike shop. 28" wheels will smooth out the bumps some. 1.6" tires could be bigger, I ride 2". Be sure to buy the smaller frame, the 19.7" frame would have you leaning forward quite a bit.
20 mph limit, class 1 so no throttle. The 9 speed shimano gear cluster should be reliable if you don't buy the nuvinci CVS hub. the hydraulic brakes may require professional maintenance at some point; I'm rather afraid of them and bought mechanical disks. But I stay in summers 35 miles from the nearest bike shop, I have to be able to fix the bike by myself and get home. Most bike shops will not touch an electric bike they didn't sell, even to repair something like brakes that are common to all upper end bikes. So make sure you have a bike shop in mind if you order off the internet. Or can afford that mobil service that comes to your house. The piaggio motor is low volume; you're not going to get a lot of help for it online if there is a software problem or something.
I'm 69 and riding 20 miles a week in the winter and 70 miles a week in the summer. I didn't start that way, when I quit work 11 years ago I wasn't up to those distances. But you can build up.
