In the narration he mentions that a 24 speed gear set, or
even more,
would be perfectly feasible. No wires, no cables, either.
I estimate that a New! Innovative! Revolutionary! Better!
bicycle transmission has been invented every two years or so.
I would expect a hypoid gear set in an oil bath to be

an open crown & pinion set?
