As I understand it, peak motor watts is designated by the volts x amps that the bike posses (ex: 36V x 15A = 540 watts)

Here's the quandary:

This E3 ProTour is listed as a 500 nominal watt ebike, yet it's battery watt hours is only 417.6. Isn't that a contradiction? If its peak watts, not even nominal, is 417.6, then how is it claiming 500? https://electricbikereview.com/izip/e3-protour/

Here's another scenario, though:

This Specialized Turbo Vado 5.0 is listed as only a 350 watt ebike, yet it pumps out 604.8 watts. Couldn't the nominal be considered higher? https://electricbikereview.com/specialized/turbo-vado-5-0/

In both instances, I assume the answer is not only easy but obvious for someone who actually knows what they are talking about.

Note: I am not directly comparing the bikes or claiming they are similar. I used them both as individual examples for this question.

Thank you in advance.
