There's not enough focus on direct energy usage or storage in general. If you want thermal energy, collect and store thermal energy. If you want mechanical energy, use that directly (and I guess compressed air and hydraulic head count as mechanical energy storage).

What I think would be cool for an exercise bike is to just have a power takeoff of some sort. Lots of bikes use a flywheel already, but even if they didn't, but you could hook up a PTO to a flywheel or a charger so that in a pinch, you could charge your phone or whatever. Probably wouldn't want to use it if you had a better option, but nice to have in an emergency. Like those wind up flashlights.
