All of my riding over rough ground is at low speed. I prefer to be in control of the power output of the motor and my gear selection rather than it be automatic. Also, on a steep hill I don’t want to have to put more torque onto the pedals to get an increase in assistance. I’d rather just flick up a mode.I’ll look forward to getting my motor upgraded and exploring the eMTB modes, I cant say that I’ve clicked with riding my Powerfly at low speed over very rough ground yet.
