University Indonesia has developed several electric vehicles, one of which is an electric bus. In order to fulfill the local content of this vehicle, reverse engineering of the R260 ladder frame type chassis is carried out. In this paper, to fulfill the local content, we used material of the ladder frame is type SS 400 from PT. Krakatau Steel. After the model was created successfully with finite element software, a static analysis was carried out by taking the von-misses stress and the deflection from the simulation results. Loading is carried out evenly over the two main beam ladder frames totaling 14,200 kg. The support placed in the mounting position of the front and rear wheel leaf springs. The distance of the front overhang is 2380 mm, the wheelbase is 6000 mm, and the rear overhang is 3290 mm. The resulting approach is carried out assuming a three-beam and two-overhang beam model. The results obtained include a maximum von misses stress of 75.8 MPa, a maximum deflection of 2,568 mm and the lowest safety factor 3.2.
