A vehicle reference point and the moment produced by each component at that position were used to compute the centre of gravity. A 1kg component 10 cm from the reference point has a moment of 10kgcm. This is calculated for all components and divided by their total mass. Thus, centre of gravity is determined. The base, two BLDC motors, and all its components weigh about 40kg. Therefore, the motor power and torque rating calculation uses 100kg mass, assuming 60kg for the basic human. Based on chassis frontal area, drag coefficient, and tyre rolling resistance, the following were estimated. Steps to calculate motor power:
