To the OP's question, around 16 months into my ebike ownership and riding (which was the first bike riding for me in ~25 years), I rediscovered that I still owned my original pedal bike, an early-90's Bianchi 21-speed. That bike defeated me back in the day, and I maybe rode it 10 times total, before putting it away "forever." It had been out of sight/out of mind for many years (I'd been operating under the mistaken belief I'd sold it many years ago) -- it was hiding out in my condo's storage bin ever since I moved into the building, 15 years ago...
So I got it fixed up and road ready, and now I try to ride it a few times each month. The ebike remains my preferred office commuter, particularly to keep the sweat down, but the Bianchi is actually fun to ride now; I never would have predicted I'd say that (based on how painful the biking experiences were for me, 25 years ago, when I never built up stamina or strength between very infrequent, painful rides.) I'm heading out for a ride in 2 hours -- undecided which bike I'll take today, but I'm leaning towards the Bianchi.
