Abstract The following work consists of the mechanical Computes Assisted Design (CAD) for an electric bicycle, which involves a detailed and structured process ranging from the creation of individual components to the integration of complete systems. A comprehensive global review of current e-bike technologies was conducted, focusing on the selection of lightweight and strong materials to optimize the energy efficiency and maneuverability of the bicycle. The chassis was designed primarily from carbon fiber. The selected electric motor has a capacity of 2000 W, providing an optimal balance between power and efficiency, enabling the bike to reach an autonomy of 90 km and a significant range. This project brings an innovative solution to the e-bike market using advanced design and careful selection of materials, resulting in a lightweight, durable and efficient vehicle. The novelty lies in the integration of advanced design technologies and high-quality materials, which not only improve the user experience, but also promote sustainability in urban transportation.
