I think Sheldon Brown has a section on them. Here is an 18 second video of one spinning.

I have two '70s Schwinn Suburbans I will be cleaning up soon...both are FFS, each with different cable types. There is apparently a small subset of folks who like it..kinda like spinner wheels on your car a few years ago I suppose...it is different.

I remember when they first came out...everyone in the shop was like, "Wha....? damn people, just take 30 seconds and learn how to shift".

Pro Tip - never buy one with a frozen gear wire.

I've seen a few of these in action, always make me smile. Apparently they're quite hard on the legs when you have to pedal backwards to use the low ratio, using different muscles than you're used to hurts!

Here’s a 9-speed ‘49 Schwinn New Worlds. Like mentioned above, this uses two shifters, one on the handlebar for the internal 3sp SA rear hub and another shifter on the top tube for the 3sp Cyclo external cluster.

There’s a 60+ page Cyclo magazine online somewhere. It’s amazing, with articles of early day riders and accomplishments along with much detail about all the Cyclo line.

That front freewheel system might work well with a mid-mount AC electric motor—not only would allow power without pedaling, but it could be used for regenerative braking with an appropriate controller. Might be something that will show up in the next few years as a "new" invention.
