No, I'm not wanting to make rules, and as I said earlier my view, quite strongly influenced by the extensive discussion in this very thread, is that I am not really bothered about actual power output PROVIDED those EAPCs modified or built with peak output power capability way beyond 250W are strictly limited to 25km/h assisted speed.
We cannot expect to have both lax interpretation of what 250W is supposed to mean, and blithely exceed 25km/h without the sort of reactions that non-EAPC riders express.
My interest in the test, and it is a while since I read it in detail, is that it does not establish the maximum continuous power CAPABILITY of a motor, and the flexible approach to RATING any motor at all as 250W according to the test is another guaranteed friction area with anyone who is not the EAPC side of the fence.
Specifically, my logical mind has trouble with rating a motor that would pass the test if tested at say 350 or even 500W at 250W just because it hasn't been tested at higher powers.
That may not be clearly enough explained, but best I can manage after a long day on a roof!
