I wonder how the bike (marketing) industry would cope with a
CVT-equipped bike? With no longer being able to use the number of gears
to separate categories, what would they do instead?

Google NuVinci, it's been released in the fairly recent past and
according to all the reviews I've seen thus far works very well indeed.
the current Gotcha is the hub weighs about 4 Kg, which is a lot in bike
terms. But it's version 1, I imagine it will improve.

Personally, I'd love CVT, just as soon as the costs and weights come
down (previous implementations have been rather inefficient AIUI, but
from what i read the NuVinci has got at least most of that sorted).
Rather than say "27 gears" you could differentiate bikes with practical
gear range, which unlike the "27 gears" would actually impart some
useful information... so I guess marketing might not like it so much... ;-/
