IMHO power is excellent with the Shimano drive system and you can customize both Trail and Boost(not eco) via bluetooth. One thing I did to my bike was update the firmware via bluetooth mode and I set Trail to max(from medium) and Boost to medium(I think it was on max) and I can climb most anything unless it gets too rocky and I would classify my skills as a novice rider. I ride street mostly on eco(unless going up a steep street) and mostly trail mode when on the trails. Occasionally using boost when the going gets really tough but that is rare and the stronger you are the less you need boost. I am going to have to ride my friends Haibike again with the bosch system and will comment on the difference.
