This project focuses on the design and development of a Hybrid Electric Bicycle using solar and dynamo charging systems. The bicycle is powered by a 250W rear hub motor connected to a 36V lithium-ion battery. To improve energy efficiency and reduce dependency on external charging, a solar panel and dynamos are integrated into the system. The solar panel converts sunlight into electrical energy, while the dynamo generates electricity during wheel rotation. These additional charging sources help increase battery backup and improve the overall efficiency of the system. The hybrid electric bicycle provides an eco-friendly and cost-effective solution for short-distance transportation while reducing fuel consumption and environmental pollution.
