Abstract: The transportation sector has long overlooked the specific mobility challenges faced by individuals with lower limb disabilities, especially those who depend on motorcycles for their independence. While motorcycles remain a widely accessible and economical mode of transport, their traditional foot-operated gear shifting mechanisms render them largely inaccessible to differently-abled users. This study introduces Easy Shift, an innovative solenoid-based electromechanical gear shifting mechanism developed to eliminate the need for lower limb movement during gear transitions. The system integrates linear solenoid actuators with a hand-operated double-pole double-throw (DPDT) switch, effectively replicating the push-pull motion of conventional gear pedals. Designed to be compact, modular, and powered by a 12V battery, Easy Shift can be retrofitted onto existing motorcycle models with minimal structural alterations. The prototype, installed on a Hero Splendor, underwent extensive testing and achieved a gear actuation accuracy of 98%, with a consistent response time between 1.2 and 1.8 seconds. Field trials involving differently-abled riders revealed a 95% satisfaction rate, with users reporting increased ease of control, confidence, and operational safety. Moreover, the system has been architected for scalability, with provisions for future enhancements such as microcontroller integration and automatic gear selection based on RPM feedback. Beyond its mechanical innovation, Easy Shift represents a human-centered solution aimed at promoting autonomy, dignity, and inclusive mobility for a traditionally marginalized user group. By bridging engineering functionality with social impact, this research reimagines two-wheeler accessibility through the lens of empathy, precision, and forward-looking design.
