Abstract The goal of this project is to design, analyse and build a self-balancing single wheel bike for use as a transportation tool for someone travelling 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.

INTRODUCTION A self-balancing electric bike is a type of unicycle that is an electric vehicle that uses sensors, gyroscopes, and accelerometers in conjunction with an electric motor to assist a rider with balancing on a single wheeled vehicle. Two things are certain in this crazy world - unicycles are cool and unicycles are seriously hard to ride. Well no longer. Now anybody can clown about on a unicycle and what's more, you don't even have to pedal. Most people can learn to ride a bike without much problem. Humans are adept at balancing laterally left to right and the gyroscopic effect of the wheels makes it easy to stay up once on the move. Remove one of the wheels to make it a unicycle and the tendency to topple backwards or forwards around the single axle is almost impossible to avoid. Seasoned unicyclists manage it by using the directly connected pedals to constantly adjusting the wheel backwards and forwards underneath them. Using gyros, accelerometers etc., monitor the orientation of the unicycle and via a processor, and a bunch of clever algorithms, a hub-mounted motor either speeds up or down to maintain axial forwards/backwards balance. Just like the Segway you lean slightly forward to go forward and back to brake. Unlike the Segway however, accidents are much less likely since you can just quickly put your feet down to stop! The other advantage over a Segway is that you don't look like a dork This report will next discuss the methodology used to develop a self-balancing bicycle, including the development of two potential design concepts, the development of strategies to balance a bicycle for a given design concept, and description of the principles behind the physical, electrical, and computational aspects of the system. Following the methodology, results will be presented based upon data collected during the operation of the system and the status of the compliance of the prototype to the specifications set forth in this report. This report will also include a discussion of the results and suggestions for future work on the system. II. OBJECTIVE OF THE PROJECT The main purpose was to design, test and fabricate a fully functional one wheeled self-balancing bike which can be used as a means of short distance transportation for a single person. It is electrical powered and driven by natural movements; forward and backwards motion should be achieved by leaning forwards and backwards. Turning should be achieved by body weight and forcing the handlebar in direction of turn. This bike has to maintain its upright position when it is not moving and when it starts to move forward or backward. When travelling with some speed, it has to use the body balance to change the heading angle. One of the goals was to design economical bike. More specifically, the project concept is stated as follows: “There is no throttle, the bike just needs you”
