Nice. How long have you been running this controller? I think my 700 has the same motor (SY2248700CUL3030PS1). I like the torque its got now. When you hit the throttle, it really lunged forward. That controller should be able to peak at almost 2000 watts! What a beast. This would be great for the hills around me.
Also, if this bike is like my 700, you should be able to remove the key lock cylinder assembly to access the other side of the internal "chute/rail" to run that throttle wire through the downtube to the existing controller location at the bottom.

Another great question! Don't want to tax the battery too much. I'm actually surprised that controller works with the stock display. That must be a KD controller, as I don't think KT controllers are compatible with KD (KeyDisplay) displays.

Well he probably nearly doubled his amps or watts, but I doubt he's using all 40 amps that the controller will allow. The Core 5 has a 750W (peak) rating on the motor, I have the same Shengyi motor on my Aventon Level. That means his stock controller is probably outputting a peak of 16amps (750W / 48V = 15.6amps.)
I am guessing best case scenario, his battery is limited to 30 amps by the BMS. That would allow him 30amps through the controller, 48V X 30 amps = 1440 Watts. If his battery has only a 20amp BMS, he's getting roughly 1,000 watts. Still a lot of power delta, and he would notice the difference.
