So I contacted the OEM of the controller I am using and they said they have fixed the code from 60, 70, 80 and 90% power assist to 20, 40, 60, 80%. But they want 100$ from me to replace my existing controller. I've passed on it as I've come very use to using the throttle to adjust and manually adjust the power as I require.
However, I've been re-thinking it and I might want to get it for the spring. Because I have to hold the handle bars all the time, my hands go a little numb at times.
