Yes, exercise bikes can generate electricity. According to [spectrum.ieee.org](https://spectrum.ieee.org/bikes-that-generate-electricity-are-making-a-comeback), there are stationary bikes that generate electricity and are used in gyms. These bikes can generate up to 100 watts of electricity per person and can produce up to 183 kilowatt-hours of electricity per year. Additionally, [livestrong.com](https://www.livestrong.com/article/418932-exercise-machines-that-power-your-home/) lists an exercise bike that generates electricity and can be used in a home gym.
Pedal-powered generators are not new to humans’ ears. Either these types of technology are seen in real life or in movies. But can an exercise bike actually generate electricity?
Yes, it can generate electricity but its output would not be enough to provide for a single light bulb.
If a person pedals a stationary bike or an exercise bike at an average continuous pace, the most energy power they could provide would be 100 watts and a maximum of 400 watts for a more experienced cyclist. Considering that a person would pedal for an hour, this means that they could power a 100-watt bulb for an hour.
