Welcome, from SE Wisconsin!
Why three times per day, instead of maybe a 30-60 minute ride ONCE per day? Are you bringing your dog along or something?
There's a guy in a local club who is a retired farmer from Iowa; he treated himself to an eBike when he turned 80 and he's still doing great. Stay in shape and keep an eye on your diet and you should have at least another 10 years in you.
Trek makes good eBikes too; some of the very best in the USA. It's a good place to start; they have lots of good choices and no bad ones, unless you've got a really tight budget. (they're good, but not cheap)
Enjoy your stay!
