Many of us are former competitors of various motorsports, working to promote E-Mobility and Skill Development who are now professionals in the automotive industry. We have two goals: to have a safe competition and see every team on the track. Top Tips for Building an Electric Bike and Passing Technical Inspection  Start Work Early: Everything takes longer than you expect  Read all rules very carefully: If you don’t understand something, ask for clarification.  Start testing your vehicle early.  Make brake testing an early priority.  Keep all the qualifying parameters in consideration while designing and manufacturing. KINDLY CHECK WITH THE IMPORTANT GUIDELINES GIVEN BELOW The new rules and regulations have been updated in the rulebook. Teams participated in previous E BIKE competition are encourage to check the compliance of the new rules and regulation and get thoroughly acquaint themselves with the new rules as several changes have been implemented. New changes, modifications and added rules are highlighted as below,  Changes in the rules – text in green colour  New added rules – text in blue colour © ISIEINDIA All Right Reserved 2024-2025 ® Rulebook Last Updated 25th February 2024 |6 INTRODUCTION A.1 About Organizer A.1.1 Imperial Society of Innovative Engineers (ISIEINDIA) Imperial Society of Innovative Engineers is the most popular and favorite E- mobility Motorsports, Education and Research Publication organization in India among engineering institutes and green energy research organization. ISIE has become the epicenter of green energy concept development in India. We are motivating Engineers &Future Engineers to work on E-Mobility. We provide a platform to new start-ups, Innovative ideas and to passionate people, who really want to contribute to society. We set out with an obsession for concept development, one that was unheard in the corridors of green energy development. It was about a commitment to creating value through innovation, quality, creativity, partnerships, openness, and learning, setting a path that is leading the world to a new direction laid out by ISIEINDIA. A.2 Event Accreditation A.2.1 Society of Manufacturers of Electric Vehicles (SMEV) SMEV is the registered association representing Indian manufacturers of electric vehicles (EV) and electric vehicle components. SMEV works closely with the central and state governments to assist the formulation of policies and processes supporting the EV ecosystem. SMEV has contributed significantly to the cause of promotion of EVs in the country through the NEMMP-2020 and FAME policy, the rationalization of import duties and reduction of local taxes and levies. SMEV is keen to play an active role in the discussion of the issues faced by the Electric Vehicle industry and practical aspects to help enhance the penetration of Electric Vehicles towards meeting the goals of our nation. SMEV is the perfect platform to learn, share and experience as we move forward into an age where alternative energy efficient modes of transportation would be in demand. Electric Vehicle Technology is gaining ground and popularity rapidly. This segment has tremendous potential as it is an environment–friendly, non-polluting means of transportation. SMEV support the activities of taken up by ISIEINDIA for their continuous efforts for the benefit of society & country as a whole and I am confident that the organization would demonstrate the same with diligence, perseverance and professionalism to make India reach at advanced level of capabilities including indigenization of manufacturing in a near term. A.3 About Skill Innovation & Employability Program (SIEP) A.3.1 Overview ISIEINDIA has created the first season of Skill, Innovation & Employability Program. The event where students from all over India will participate, retrofit and bring innovation in their E- Bike. This event is entirely different from other events, where manufacturing of the vehicle & Retrofitting both are included. This event is entirely based on the Innovation of Drive train and other aspects & integration of their innovations from the Virtual Round to the Final Round of the event. A.3.2 Objective  To raise awareness among youths towards E-Mobility. © ISIEINDIA All Right Reserved 2024-2025 ® Rulebook Last Updated 25th February 2024 |7  To skill the engineering students towards new & trending technologies through this Innovative program.  To inculcate a culture of Innovation & technologies.  Bridging the gap between the Industries &Academia.  To facilitate a career forum for engineering students. A.3.3 The Event will be in two classes: A.3.3.1 Retrofitting Class The purpose of this segment of Retrofitted bike is to provide immense riding pleasure to the users without changing the bike’s essence. A light weight vehicle of this class should provide an ultimate eco- friendly and economical cruising experience to end users. A.3.3.2 Self-Manufactured Class The purpose of this segment is to manufacture an Electric Motorbike which in future meets the commercial requirements that can help the society to incline towards the E-Mobility. The idea of introducing these classes is to encourage the engineering participants to convert an existing ICE Bike into an E-Bike and manufacture the E-Bike with new features such that the bike should have modified aesthetics. This can fulfill the needs and aspiration of young generation, who are willing to contribute and use eco-friendly green mobility solutions for the greater good of the society and the environment.
