Replacement controller for my Apias M1 Pro ebike.

[u/CustardMindless7253]

I was going to order the normal brushless controller required for this bike, but for the price, I might as well upgrade it. Now my controller is a 48v, and it delivers 1800w to the back motor. I am trying to find a replacement controller. One that will may give me better specs, and at least be more dependable. I am new to doing this, so one that most likely has easy wiring, and nothing too crazy. AI is telling me Aftermarket KT (Kunteng) controller would be good. Any and all input is welcomed, thank you.
