Is there a market for a stationary bike/generator so people can reduce their electric bill while losing weight?
May be they can be installed inside health clubs where lots of people may exercise to lose weight. All that energy wasted right now while people try to lose weight.

People are already selling these online and I don't think anyone has got rich yet. Typical cost £500 and up. Anyone with DIY skills can make one much cheaper but it's not easy to understand the electrics if you don't have experience. DIY models can use cheap E-scooter motors to generate 50 to 200 watts depending on your fitness. Don't expect to power anything more than a small laptop unless you are a keen cyclist. Reducing your electric bill with one is impractical, but it's a fun way of charging a battery in a remote location with no power..

Sorry but even a very fit athlete can only generate a very, very small amount of electric power and only for a short time. It is a good idea but not feasible.
A trained cyclists can only produce 400 watts for about one hour.

Doing a high power workout is probably around 250 watts. That would take 4 hours to produce 12 cents of electricity.

yep. especially for off grid cabins where kids can crank to produce electricity for watching television...
