Default 16 Tooth Sprocket

Lets say you you can get your bike up to 20mph pedaling on a long straight road. Who many teeth would it take to... I should say, what would be the minimum amount of teeth would it take to start the motor. And then, how fast might the bike go? Assuming the bike could handle going 90mph.

I know of the 36 tooth sprocket but what about a 26 tooth sprocket? Or a 16 tooth sprocket. I know at some point it would be like shifting into 5th gear while starting out in first (in a car).

Smart people tell me! What would be the minimum? This is all hypothetical, Im just curious and wondering what it would be like to go that fast.
