Design and Optimization of Multipurpose Bicycle?s Frame

Abstract

There are many bicycles and wheelchairs available in market and every bicycle and wheelchair have its unique design of frame. People like the bicycle as per their choice and uses. This paper represents the design and optimization of multipurpose bicycle?s frame. Only one model that work in all 3 mode ( bicycle, wheelchair , folding bicycle) by converting from one to another by some mechanical movement. In this frame when it is in the bicycle mode we can ride a bicycle as a simple bicycle and any time we want to convert into wheelchair so it can be easily convertible , and also it can be folded into compact size (almost half of bicycle). It will take a very less time to convert into each other.
