The automobile sector started shifting its dependency from fossil fuel to electrical energy in the last few decades to mitigate adverse environmental scenarios like global warming, air pollution, etc. Due to this, the battery is emerging as the new source of power. At the same time, the use of bikes for city transportation has been growing at a high rate in developed countries. For a heavily congested mega city like Dhaka, electric bikes can provide a better alternative to traditional fossil fuel vehicles. They are not only costeffective but also faster and can contribute to improved public health outcomes. With such a background study, an initiative was taken to fabricate an electric bike. This paper presents a study of its chassis design and analysis. The triangular structure was used as the basis of the design since this concept provides the best structural strength. Mechanical properties such as stress, strain, and deformation at critical locations within the fabricated chassis were compared with numerical results obtained from the state-of-the-art FEA software ANSYS. The validated numerical method allowed to simulate the dynamic performance of the chassis by predicting the forces on the structural member during acceleration and braking. It is expected that the developed numerical methodology will allow conducting exploratory designs with confidence.
