Part of an e-bike's value is mental. While you might think, with an analog bike, I don't have the energy to ride today...or my (fill in the blank) hurts so I'll skip today's ride...or there's too much wind...or many other reasons, with an e-bike it doesn't matter. That mental resistance is gone because you know you can make the ride. I often go out thinking I will ride poorly and use assist and then find myself cutting it off after a short time in the saddle. You can use an e-bike to:
1. get places faster
2. go longer distances
3. go up more challenging terrain
4. go riding when your mind/body are resistant
I think of it as the "no excuse" device, lol.
