I'm not Amish, but e-bikes actually make a lot more sense if you understand why the Amish rejected electricity in the first place. It's because, up until very recently, the only practical way to actually obtain and use electricity is to have your house wired up to an electrical grid that delivers on-demand power supplied elsewhere. This is a no-go for a religious community that views decentralization as the only path to holiness.
Remember: the Amish don't hate new technology because it's technology and they want to live in a fantasy world. They hate technology because it's a centralizing force.
What changed? Simple: solar. Solar is (mostly) decentralized electricity: once you buy solar panels you are dependent only on the continued existence of the sun for power. This actually fits into the Amish lifestyle extremely well for the same reason why it fits into the lifestyle of Nigerian Youtuber Africa Everyday, for entirely coincidental reasons[0].
[0] Most Nigerians would jump at the chance to have reliable centralized electrical infrastructure. The Amish are energy poor by choice.
"once you buy solar panels you are dependent only on the continued existence of the sun for power"
Or until the panels degrade too much or break down, and you have to buy new ones as you cannot make them. So it is still a dependency, but less strong.
The Amish buying a bunch of old PV manufacturing equipment and accidentally kickstarting America's solarpunk revolution isn't exactly something I had on my 2020s political upheaval Bingo board, but...
That still doesn't contradict their point about decentralization. When the panels need replacing you replace them from whichever suppliers are available at the time and then you're good for another 20-30 years. If you're hooked up to the grid then you owe a specific entity money every month.
