Well this is fun. I don’t know the answer for sure. 

I do not think a bicyclist can stay ahead of a sprinter for the first 20
yards. 

But beyond that, I think it is due to an inherent limitation of the speed
of the lower leg’s fast-twitch fibered muscles, coupled with the attachment
point of the muscle to the lower leg bones. This is also related to why an
80 lb chimpanzee is four times stronger than a 180 lb man, but cannot throw
a ball with any speed; the attachment point of the chimp’s muscle is
further away from the joint, trading speed for leverage. 

Between the cyclist and the sprinter, when both are ramped up to fastest
leg speed, the bicyclist now has an obvious advantage, because of the ratio
of the radius of the wheel compared to the radius of the pedal crank, which
in turn is about the same as the average radius of the runner’s foot
motion. The tangential speed of the wheel is larger than the tangential
speed of the foot by the same ratio as that of the radii.
