I would opt for direct utilization of the mechanical energy coming out
of the flywheel.  If you've got a magnetic coupling, consider it a
clutch and run it to your transmission.  Forget the lossy mechanical
to electric, electric to mechanical conversions.

I don't consider flywheels to be batteries for electric cars.  They
are a high output energy reservoir that can be filled from an onboard
low power high efficiency IC engine.  That way we have the best of
both worlds - a fuel tank of explosives and disk of intense kinetic
energy.
