Quoth John Betmanis:

The were no more "unregulated" than any other bicycle generators that I know of, aside from Lightspin.
They all get a certain amount of "regulation" from the inductance of the armature.
Modern systems have the high-tech, solid-state regulation built into
the headlights.

I'm afraid I must take exception to that characterization. It was only the _high-end_ commuter bikes that featured Dynohubs, models like the top-of-the-line Raleigh Superbe featured them as standard equipment, but otherwise they were an extra-cost option for the lower-end models.
