The size S on the carry-forward frame has a very slight curve in the top tube. The size S in the new frame does too, and it comes with a 625wh battery as there is not enough room in the downtube for the bigger 750Wh battery. However, smaller riders do tend to use less battery. The S in the new frame will be available later in 2022.
