Great Britain: the EAPC points, in plain language

Official GOV.UK guidance for Great Britain distinguishes maximum continuous rated power from other power claims. An electrically assisted pedal cycle keeps pedals that can propel the bike, a maximum continuous rated power of 250 W, and motor assistance that cuts off at 15.5 mph.

Peak watt claims are not the continuous rating. A configuration can be within 250 W continuous and still be conditional because of a throttle, a missing cut-off figure, or a mechanical problem that has nothing to do with the law.
