The Bicycle generator model is used for fun demonstrations to increase understanding and awareness of energy topics. The intention of this model is to build a straight forward human powered generator from a used bicycle and to use it to power light bulbs. This system is designed to show the conversion of mechanical energy into electrical energy. On the system, there is a bicycle, a dynamo and 8 lamps with different colors that show the power levels. When cycling, the consumed mechanical energy is converted to the electrical energy with the help of the dynamo and it provides the lights to be turned on level by level.
