The objective of the research was to design and analyze the strength of the frame with computational method. This was used to determine von mises stress, displacement, safety factor in the chassis. Based on the design results, it proves that the material used was Galvanized Steel, the main pipe diameter was 30 mm, the supporting pipe diameter was 25 mm, the size of hollow iron was 2 x 4 cm, and the chassis length was 190 cm, and its width is 80 cm. The simulation process used computational methods with variations of the riders' weight f 46 kg, 56 kg and 66 kg. With the maximum rider weight of 66 kg, the simulation results show that the Von mises stress value was 25.95 MPa, the displacement value was 0.29 mm, the minimum safety factor was 2.11 ul. It concluded that the Chassis was designed to be safe for a maximum load of 66 kg. Keywords: Chassis, Von Mises Stress, Displacement, Safety Factor, Computational
