Electrification of automobiles results in new and challenging characteristics of vehicle NVH (Noise, Vibration, and Harshness) and ride comfort. Optimized architecture of electric vehicles has been evolved for appropriate placement of electric power drives. This paper presents the experiments performed for order analysis technique to predict the vibrational behavior of conventional and electric scooters which was not used in 2-wheelers earlier and used for 4-wheeler noise predictions and for vibration analysis of rotating machinery. Vibrational analysis of source alone in conventional and electric two-wheelers carried out by order analysis and the result is presented through Campbell Diagrams to observe the critical orders along with the variation of the amplitude of vibration as a function of frequency. Target locations’ Vibration Dose Values (VDV) is calculated to assess rider comfort and is compared with the ISO 2631 standard. The higher amplitude of vibration has been observed at 23 rd order for electric scooter while for conventional scooter it is noted at 8 th and 16 th order with reference to the wheel speed. Compared to the conventional scooter, electric scooter exhibits very low overall vibration level and range is away from human perception range resulting in good comfort.
