Cycling Power in Watts

If you had to generate electricity with a bicycle, how many light bulbs can you power? Well, consider that an average bicycle on level ground in still air needs 100 Watts of power to cycle at 12mph. If you wanted to add an electrical generator to your normal cycle, the effect would be like going up a hill. You feel this resistance because you would be working against the electromagnetic resistance in the coils of the generator. To power a 60W bulb, it would feel like you were climbing a 4 percent grade…you’d break a sweat. So on your next bike ride, you could light one room in your house. For comparison, an electric range could use up to 12,000 watts, I’m guessing just one burner on high would use 2000 watts.
