"Overkill" gearing on most bicycles

Manufacturers should look at providing three gear bicycles again. I
find, for myself anyway, that an 18 speed gear system is "overkill"
for the bicycle commute everyday. Single speed cranks are not enough
and multi-speeds require too much servicing. A single sprocket on the
wheel and three sprockets on the crank would do the job for most
cycalists.
