I ride mostly in pas2 to get that range, but if I go slowly,( pas1, 8 to 12 mph), i can get even more. I doThat's great range for such a comparatively small battery! As the doctor has ordered more exercise I've given the throttle a rest and have been amazed at how little power is drawn in PAS 1 and 2.
use the throttle for a second or two to bump up speed crossing intersections or going into a rise. Yesterday
was also the 1st I tried throttle only for 1/2 a mile just on a lark. The way you ride can greatly extend mileage.
I get far more from the 13ah than I ever did with the 21ah on my other now parts bike. It comes mostly from
using a lower gear with a higher cadence.
