Commercially available flywheels

[jamesson]

Do the flywheels used in automobile transmissions have input torque suitable for the equivalent of a bicycle pedal? If not, how troublesome is it to assemble a gearbox to create sufficient torque? Also, is there some mechanism I can use to dynamically (eletronically) adjust input torque? Are there any other commercially available flywheels I can look at?

To do what? It is hard to answer your question without the context of knowing what you are trying to accomplish. Do you want to add a flywheel to your bicycle?

...or replace the flywheel of a stationary bike? I bet you could cannibalize an old stationary bike for cheap.

Input torque from what? A motor can have a speed/torque controller, often just by adjusting the voltage. A stationary bike typically uses either a mechanical brake or the equivalent of a generator (electromagnetic resistance).

Yeah, you guys are right. It was silly of me to expect a good answer without explaining my plan. I'm looking into a combination pedal-powered generator/trainer that I could put a "normal" bike into without disassembling it.

I suggest that you first examine pictures of commercial stands that do the same. See how they are designed. I just looked at several pictures on Google images and none of them use a flywheel. Search for something like:
