> reduced rotational inertia translates to faster acceleration

\aside why not smaller (radius) wheels? Use higher gearing, and accept the bumpiness.

Though for touring aot commuting, there's something pleasant about higher inertia.

Larger wheels roll over obstacles better. That's why most mountain bikes are 27.5" or 29", which is about as big as you can go without causing too many other compromises.

Bumpiness isn't just a comfort issue. Your body ends up absorbing a lot of the up and down motion, which drains your forward momentum.
