I would think most rear hub 36v/48v 500w with 5 PAS settings and 7speeds feel similar. If that's the case, on a Ecotric 26" fattie. PAS2/7th gear for best range. PAS 2 / 4th or 5th, inclines. Hills, PAS 3 or 4 and whatever gear has a feeling of resistance on the pedal stroke. If my knees start acting up. PAS 5 using throttle to adjust amount of power used. The battery indicator really helps to find the sweet spot on consumption. In the 6 odd months I have had my bike I have used throttle only 2 or 3 times. My wife on the other hand very sparingly uses the motor. Her bike (20" folder) is another way to exercise. She likes the added weight when peddaling.
