I was wondering how exactly the support of the motor of the stromer works in order to save battery. In position 1 for example, the manual says that it supports 150%. So the motor gives 150% of the power I give. So does that mean that if I pedal really hard in position 1 the motor also uses much more energy? So it would actually save battery to put the support in a higher position and work a bit less? Does this make sence?
