We have developed an innovative cycling device that harnesses excess calories and converts them into electricity during exercise. This groundbreaking device not only promotes personal health and fitness but also generates electricity for charging electronic appliances like mobiles, tablets, laptops, and more. The generated energy will be conveniently storable within a detachable battery, effectively serving as a portable power bank. Furthermore, this device will revolutionize the lives of individuals working in corporate sectors and academic offices, as well as fitness enthusiasts, by effectively promoting their health and converting excess calories into clean and sustainable energy.
