Construcción de un sistema handbike eléctrico acoplable a una silla de ruedas manual

Abstract

This project focuses on the construction of an electric handbike designed specifically to attach to manual wheelchairs, offering an innovative solution to improve the mobility of people with disabilities. In terms of design, a technical analysis of the essential elements and components was carried out to offer a high level of performance solution at a considerably lower cost compared to other handbikes for commercial use. One of the distinctive points of the handbike is its structural resistance, which was designed to meet the standards of daily use without compromising the durability or performance of its components. This approach not only ensures user safety but also helps keep the cost of system maintenance within an affordable range. Several tests were carried out to evaluate the performance of the electric handbike and validate aspects such as traction, structure, stability and ergonomics. Testing included performance evaluations on varied terrain, from cobbled surfaces to more uneven terrain, with the aim of ensuring the handbike's adaptability to real-world environments. Speed tests were also carried out on routes on different terrains such as cobblestone, cobblestone, flat cement and asphalt, with variable loads to evaluate speed and stability in everyday situations. One of the most important characteristics of the designed solution is its autonomy, since it allows prolonged use with a single battery charge. The tests carried out allowed us to validate the effectiveness and resistance of the electric handbike, ensuring a product that meets the quality and performance standards expected by end users. The built handbike represents a novel electric mobility solution for people with disabilities in their lower extremities, an optimal balance between price and quality.
