I went electric to assist old knees on hilly terrain. I ride in PAS mode only and ignore the throttle. I'm still pedaling all the time - I didn't want a motorbike. The low PAS setting results in about 14 - 15 mph which is comfortable on crowded MUP trails. I often tun it off on level stretches, and since the local trails connect several parks with playgrounds, ball fields, swimming areas, dog parks, etc. I always turn it off when riding through those busy areas. On a tough hill I may occasionally bump the PAS setting up one step - depends on the knees that day.
