I had electrics a few years before I recently built a couple of 2 strokes (in frame and a friction). The electrics are very nice, and you can ride them anywhere, with practically no maintenance ( I haven't done anything except air for over 1000 miles on one of my bikes), friends of mine have over 5K with nothing but tires and pads. My Solex was the e bike of it's day 50 years ago, fuel efficient, quiet, cheap and durable, and it still serves that same purpose today. If you keep things a long time like I do, the downside of the e bikes may be battery replacement/sourcing/cost. Fuel bike parts are still way cheaper, a new engine is sometimes 1/3 of the cost of a battery pack. I like having both.
