I have no need for one. My version of riding bicycles involves doing it without a motor/pedal assist/call it whatever. As Hemingway said ‘It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and can coast down them…. Thus you remember them as they actually are, while in a motorcar only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.’ That’s kind of why I ride bikes. Appreciate that others may have other reasons.
My opinion is that E-bikes are a solution to a problem that largely doesn’t exist. As an alternative for those who can’t ride a conventional bike – fine. I do like the application of them in urban areas as a practical delivery vehicle or commuter for longer journeys. As a recreational tool? Very concerned about the impact they might well have on our already limited access rights and perception with other trail user groups.
No doubt those that have used them have no problem justifying them. I do not consider them to be cycling as I know it though. Sometimes making things easier isn’t always the best idea.
