Salut Pierre.
Im 183cm and well the Medium was good for me.
Now 170cm, I wouldn't recommend extra small but small!
Extra small would fit 155cm to 165cm I believe.
Now, you need to know that for me there is big flaw in the conception of this bike and it is the geometry. Looks good, true, therefore try to take a corner with it full speed, found out the pedal will touch...even if you don't lean much....
