Figure out first where you would charge the battery. I know nothing about e-bikes, I was not plugging into mains for anything.

When I was there in June 2019, I stayed at two National Park campgrounds, if I recall correctly they had a special on an annual pass price that came with discounts on campsite fees and I only had to stay there a couple times to make that annual pass cost effective.

It is my recollection that they charged more for sites with power than for tent sites without power. I also stayed at a small HI Hostel, but I do not know if the hostel system still has a hostel there after covid.

This was the worst hill I had to climb with a 13 percent grade.



It can be quite windy there, and wet. And parts of Cabot Trail are a food desert.



My GPS data from my trip is on a different computer, so I can't elaborate more on specifics of my trip. Here is a map of my trip, but as you can see my map covers more than just Cabot Trail.



If you have a reason to ride across the causeway on a bike, I waited until I could not see any traffic at all behind me before I rode across, that way I did not have a big long line of angry drivers behind me when I got across. But I suspect you would not be riding a bike across it.
