angle (that is, when climbing a hill some systems increase the PAS percentage).
That sounds right. My DAS-Kit hub drive seems to be either on or off at the same power depending on speed and PAS setting when you start/stop pedaling up until you get close to the top speed of that setting. Then it seems to taper the power off. So the acceleration from stop is always the same no matter what PAS level. If you actually want to change the amount of power, you need to go into a password protected menu and change the power output of the motor.
I tend to use my Bosch mid drive in almost exclusively EMTB mode because it feels the most like riding a regular bike.
