I stated before that I am going to be doing it for fun after you pointed out that it would be not something to do for a profit. No ROI needed.

And when I do store up enough power to run my ant s3 for an hour or a few hours, I can call it a success. Even if it isn't the most profitable or reasonable way to get power, it will still be fun to do.

Yes this is true but what machine would you be using? All the ones I have seen are next level expensive.

I will be using some neodymium n52 grade magnets along with coils of enameled copper wire. Mould those in separate resin disks and mount them with the coils stationary, magnets rotate. Hooke those up to a battery bank(batteries charged with electricity through charge controller and passed to electronic through inverter.)

That is all that is needed to create an electrical generator/alternator.

It's a fun DIY project you can make pretty cheap.

The good thing about making your own is you can determine the size of the coils and magnets which determine the electricity being generated. The speed of the rotation also determines that so it's a combo of speed and size.

How much can it generate from a human peddling is what I will find out when it's built.

Altogether you can make a DIY generator for as low as $100 depending on how big you want the magnets and coils to be. The full system would be a bit more but you can keep it pretty cheap.

I'm using some big 4" x 2" x 1/2" n52 magnets with 30 parallel wraps of 14 gauge copper enameled wire to see if I can get a good generation going.

If it doesn't produce at least what MrTeal said, around 150W in 2 hours, I can always turn it into a wind turbine or hydroelectric generator and try again.

You could probably make one with some n42 cylinder magnets around 1" diameter 1/4" thick and 16 gauge enameled copper wire 15-20 wraps for around $100.

The rest of the supplies to store the electricity and use it could be as cheap as $100. That would include the battery, a rectifier, charge controller and a small inverter. This is depending on which ones you use, of course, and the maximum watts you are looking for.
