When it comes to self-balancing personal transportation devices, it looks like the Solo wheel, Honda U3X, Uno, and Segway could all be in for a little competition. A monowheel/bike is a one-wheeled single-track vehicle similar to a unicycle. Instead of sitting above the wheel as in a unicycle, the rider sits either within the wheel or next to it. Usually driven by smaller wheels pressing against its inner rim. Most are single-passenger vehicles, though multi-passenger models have been built. The goal of this project is to design, analyze, and build a self-balancing single wheel bike for use as a transportation tool for someone traveling short distances. The project consists of a research phase in which similar systems have been investigated to help determine a sensible design approach and to establish appropriate design specifications; a design phase in which a model was designed with certain assumptions to meet the aforementioned specifications and a construction phase, in which the vehicle was built and tested. Monowheel looks like something out of a science fiction movie, but monowheel is, in fact, real, today, mono wheels are generally built but from the 1860s through to the 1930s, they were proposed for use as serious transportation. The idea may sound extreme, but the science behind monowheels is solid, at present, because of the surging consciousness of pollution and energy shortage crises, automobiles and motorcycles are no longer the best for transportation. As the price of petroleum products growing nowadays, there is a need for a cheaper and more efficient form of transport
