It works really well. Mrs had a cold recently while we were on holiday. Option was riding alone or ebike hire. If anything it was too powerful. She was easily faster on the climbs. In fact she could comfortably push me faster than I could pedal. I had a little go and despite being cheating it was actually great fun. Made the climbs quite similar to gentle downhill. We both really enjoyed it.
Probably would be better with the power a couple of clicks down from max to actually get some exercise and for all day battery. A bit compromised on the downs but more due to the hardtail and basic forks than the weight.
