Recently, I have been involved with the electric skateboard community because of my custom ESC. I get many questions about motor kv, gear ratio, current, voltage and efficiency. In this post, I will try to explain how things are connected and how to chose the right setup. I will try to keep things simple and not involve too many equations to provide a good intuition for the DIY community. The assumption in this post is that we are using an 50mm-60mm hobby outrunner motor.
