How would I retrofit a spin cycle to gen and store energy.

I saw the stage 2 innovations documentary on a cycle that can generate and store enough energy to run rural households for 24hrs. I wanted to expand this for a small project with a local spin studio.

Reason being I noticed that for a 45 minute class, riders avg

489 - 1000 Watts,

439KJ - 1000kJ

81-200 RPM

Over 38 bikes, 5 classes a day.

I know the economics is bad for a single rider but with these numbers and a constant customer base, I think we may have something here.

I wanted to ask. Where can I find resources on retrofitting a DC generator, connecting this to say a Tesla Powerwall or AUO Power Legato, then to an Inverter to redistribute the energy for the studio?

I have an electrical engineering background, but built small scale micro electronic projects, not ones larger on this scale.

Any help would be highly appreciated.

Start by researching solar photovoltaic power storage. The input voltage and power range from a bike generator would be similar to that provided by small solar panels (50-300 watts) so the exact same technology can be used.

The figures you quoted seem overly optimistic. An average healthy human on a bike can provide only about 70-100 watts on a sustained basis.
