PA is quite beautiful. I was in downtown Pittsburgh one 4th of July weekend. We walked from the Marriot to the nearby hill and watched the fireworks. Pittsburgh itself was quite hilly, and we took my manual shift car. My wife would not drive it after we passed thru Ohio.
The only long grades that we've ridden on ebikes are converted train railways out West, so they are fairly gradual, but will tire the riders on regular bikes. We had my wife's 300W ebike on that trip. No problem for her, but I had advised her not to pass anyone in riding gear unless they were really slow. We'll did pass a few guys but tt was 6000-7000 feet after all. Two days earlier, we did a 1 mile hike in Rocky Mtn NP at maybe 7500', and it gassed me out completely.
