I am looking to make my daughters super 73-z1 faster and give it more range. I'm using a Kt lcd 3 with a kt 9 mosfet sign wave controller with a 5p 48 volt battery. Here is a link to the controller and lcd I bought: https://www.aliexpress.com/item/36-48V-250-350-500W-Electric-Bicycle-Scooter-Brushless-9-Mosfet-Sine-Wave-Controller-with-KT/32972931563.html?spm=a2g0s.9042311.0.0.4c044c4dzFp2lt
I hooked the wires up with all colors matching. The controller also has a white wire with the hall wires. Speed sensor? I hooked it to the white wire going to the motor. Only thing that isn't hooked up is pas and headlight. I used a very good youtube video to get my Kt lcd3 set properly. The problem I am having is the motor works when it wants and doesn't sound good when it decides to work. Speed ramps more power when it feels like it if it works. It sounds rough. I tested motor again after on a stock z1 and it still works fine. I tried installing motor phase wires in all possible configs and it did not help at all. I also tried a different thumb throttle. It acts like a bad throttle. Wondering if I have a bad controller or if it's even compatible with this motor. I will post a picture of the motor info. All help would be very appreciated.
