How to Make Solar Electric Bike Hi friends today I am going to show how to make Solar Electric Bike with 12v,125w Loom solar panel. The bike is self charging by the solar panel .At first have used 24v ,12A battery then I replace it by 24v ,18A lifepo4 battery. At direct sunlight it takes 3-4 h to full charge. If you run the cycle at the sunlight after full charge the range increases 30 to 50 km. The material I have used you can get here 1. Loom solar panel 12v ,125w (mono) https://www.loomsolar.
