Abstract
Mobility is a fundamental need, yet many conventional vehicles are inaccessible to persons with lower-limb disabilities. This project presents a Three Wheel Handicapped Steering Propulsion Cycle designed to provide independent, human-powered mobility using only the upper limbs.
The vehicle features a stable three-wheel configuration, an ergonomic seat, dual hand levers that simultaneously drive the rear wheels through a chain-sprocket mechanism and control the front steering, and a reliable braking system. The design prioritises low cost, ease of fabrication, stability and user comfort.
It serves as an excellent final-year mechanical engineering project focusing on design, kinematics, ergonomics and assistive technology for differently-abled users.
