cycling priorities evolve.
like well aging humans.
2 hour ride with class1, no throttle, rear wheel motored road e-bike, is just as aerobic as a 1 hour ride of shorter distance. (i have a big hill home and hilly routes in abundance, so I use that as an excuse.) Used to have the EU standard on controller which would cut out at 12-13mph. That was adequate.
When mixed with substantial non-motored rides, I have seen no loss of muscle. 1 ebike + a dozen road ready traditional bikes.
Roll On - any way you can!

16 - 18 mile one-way "commute".
