I have an inkling notion that someone goofed when they programmed the internal controller cut off speed. The code is probably missing some "if then else" clausesHi just to let you know if I set the speed to 27kph it works well and power assist kicks in as it should so happy so going to leave it there
This post swayed my decision to forge ahead with the GSM build. I will try at 25 km/h with the external controller just to see but 27 km/h cut off is my sweet spot anyway. I am running my hub at 26 km/h cut off so that it will cut off at 25 and a bit (about 25.4 km/h) well within the 10% tolerance.
