Well, for maximum braking power you'd want to have max power for both
wheels. Because the rear tends to lose braking power as weight shifts
forward, moving back just far enough to balance the effect ought to produce
the max. I suppose you could tell where that is by trial and error,
determining how far back you need to move so that both wheels skid at the
same time.

No, wait a minute - on reflection it seems moving back would reduce front
braking power. Maybe it doesn't make any difference at all, so long as both
wheels stay on the ground or, theoretically, maybe not even then, until
braking itself causes the rear wheel to lift.

if you could position your center of gravity anywhere, to ensure
maximum braking power, where would it be?

obviously over the front wheel is no good, you would flip.

there is a point, leaning either ahead of the front wheel, or
behind the back wheel, that the opposite wheel is off the ground.

clearly those are 2 limits, the answer must lie between them.

if there were very little friction, it would hardly matter.

assume a level road, brakes that can cause a skid no matter what.

ok, so where do you sit?

state assumptions, like coefficient of friction between tire and road,
weight of bike and rider.

show your work.

now for extra credit, make it a function of road slope.
