I completed version 2 of my kids quad EV conversion. I figured y'all would like to see it in action and to know some details on how the build went.

Top speed well over 50mph, can support an adult rider. Very quick! I am getting about 81wh/mi with an adult rider.

2. EM150-2SPsine wave motor controller
3. DKD LCD speedometer

Nice professional touch with the display.

I have been working on an extremely similar project, but yours has better electrics.
I have a Polaris 90cc frame from the early 2000's. Can't figure out the year or model, but I have been assuming sportsman.
Cyclone 3000w
72 Volt battery
Cheap 40amp control, non-programable that came with motor years ago.
