CyGen (Cycle Generator) is an innovative exercise solution that integrates fitness and renewable energy generation. Designed as a static bicycle, CyGen allows users to engage in physical activity while simultaneously converting mechanical energy into electrical energy. This power can be used to charge small electronic devices—such as smartphones—at an average rate of approximately 1% battery life per minute. The primary goal of CyGen is to promote a healthier lifestyle by encouraging regular exercise, while also fostering energy consciousness and sustainability. By linking personal fitness with green technology, CyGen represents a step toward eco-friendly daily habits, particularly in urban settings where energy consumption and sedentary behavior are on the rise. CyGen has potential applications in homes, gyms, schools, and public wellness centers, offering both health and environmental benefits in a single, user-friendly system.
