Analysis of static mechanical properties of electric bike frames using finite element analysis (FEA)

E-bike (Pygmy) as a two-wheeled vehicle used for urban public transportation users in traveling the distance from home to bus stop/station, bus stop/station to the office, or vice versa, needs to be designed lightly and portable with foldable capabilities. To fulfill the use of the frame when given a load, it is necessary to analyze the performance of the frame by conducting static testing on the frame. Static testing is done by analyzing the response of the frame when the e-bike is occupied by the rider but not in use. Component loads that need to be analyzed are the load from the battery component as the most significant component load in the e-bike and the rider load as the main load. In the conditions of the existing AISI 1020 Steel material with variations in the rider's weight of 60, 70, 80, 90 and 100kg and a battery weight of 3.5kg, the max equivalent stress is obtained below the yield stress value of the material when the tensile test is carried out on variations 1 and 2 with e-bike mass 21kg and 20.787kg. Reduction of e-bike mass with a max equivalent stress value below the yield stress value of a material is obtained on Aluminum 6061-T6 material in variations 1 and 2 with e-bike mass 16.14kg and 16.06kg and Aluminum material 7075-T6 in variation 1, 2 and 3 with e-bike mass 16.27kg, 16.194kg, and 16.117kg.
