Centre of gravity is irrelevant for an inverted pendulum. With an electric device weight is important-even if you cannot reduce the weight of the payload. Reducing the weight of a Seg by 25% has a small but measurable effect on the total weight being moved and there is absolutely no point making it heavier than it needs to be, it wastes resources and reduces performance- think how great the P was. If you have to lift it into the back of your car you will definitely notice the loss of 10/12 kg and that seriously impacts the utility of the device and where you can use it- If you could get it down to 25Kg with a quick release column and wheels, you COULD carry it in a shoulder bag and that would be a real game changer for the private user market.
