Normally my wife & I will rent bikes when we're on vacation. She really doesn't ride much other than when we're on vacation on a bike tour. Anyway, our last vacation I rented her an e-bike and I had a "regular" bike. She actually enjoyed it, and love the fact she was able to keep up with the group. I'm thinking of getting her one so she can ride here at home.
Like others have said, when the time comes, I will definitely get one so I can continue enjoy riding. Hopefully, that won't be anytime soon...
