Do coarse inch-pitch sprockets fail to give you the precise gear ratio
that you want on your single-speed?
The solution is to stuff 8 gears and 2 chains inside a pair of hollow
crank arms:

The design also eliminates unwanted ankling--those platforms stay
level, if everything goes right.
The dip in the back of the pedal platform accomodates the heel of the
rider's shoe.
