The main aim of this project is to design and fabricate an e-bicycle with renewable energy source solar.   A solar panel is a large flat rectangle, typically somewhere between the size of a radiator and the size of a door, made up of many individual solar energy collectors called solar cells covered with a protective sheet of glass. The cells, each of which is about the size of an adult's palm, are usually octagonal and colored bluish black. Just like the cells in a battery, the cells in a solar panel are designed to generate electricity; but where a battery's cells make electricity from chemicals, a solar panel's cells generate power by capturing sunlight instead. Electric motorcycles and bicycles are plug-in electric vehicles with two or three wheels powered by electricity. The electricity is stored on board in a rechargeable battery, which drives one or more electric motors. Electric bicycles (as distinct from motorcycles) have a step-through frame. All electric bicycles and motorcycles provide for recharging by plugging into ordinary wall outlets, usually taking about eight hours to recharge (i.e. overnight). Electric and gasoline powered motorcycles and bicycles of the same size and weight are roughly comparable in performance The E-bicycle model requires a hub motor, throttle accelerator, gate for brakes and batteries along with solar panel-based charging circuit model. The system also uses solar energy to charge the battery.  In this project we are using solar panel, Reverse polarity preventer cum polarity corrector, AC ripples neutralizer, unidirectional current controller and a rechargeable battery which has high charge storing capability and long durability.          

The major building blocks of this project are:

• Solar panel.
• Charging circuit.
• Hub motor
• Throttle accelerometer
• Gate switch.
• Bicycle
