The development of small-scale electric vehicles, particularly electric  Go-karts, demands a drive system capable of combining energy efficiency with adequate torque generation. One of the main factors determining this performance is the gear transmission system, particularly the transmission ratio. Inappropriate gear ratio selection can result in reduced acceleration, increased energy consumption, and limited maximum vehicle speed. Therefore, a structured design and analysis process is required to obtain a transmission ratio that matches the characteristics of the electric motor. This research aims to design and analyze the optimization of a gear transmission in an electric  Go-kart using an engineering calculation approach. The analysis is based on the torque and power parameters of the electric motor, as well as a literature review of relevant scientific journals and technical books. The research methodology includes mathematical design of the transmission system, evaluation of the effect of gear ratio variations on wheel torque, and acceleration performance simulation.
