The whole throttle vs pedal assist distinction makes way less sense than delineating the difference based on power.
Wattage is basically meaningless. There is nk standard way to measure it. Almost all "250 watt" ebikes consume much more than 250 watts of electricity at full throttle, and can produce much more than 250 watts of mechanical output for seconds or minutes at a time.
