I fully agree Jim, and it's really the manufacturers of the bikes who should make that available in the way that car and motorcycle manufacturers do. Just giving the legal average consumption definition isn't good enough. Where an e-bike supplier gives the legal figure as the power output of a bike, I believe they could be charged and found guilty under the trade descriptions act.
Gross powers of current legal e-bikes range from 180 watts (Bliss folding bike) to 700 watts (Powabyke), with net outputs averaging 80% of those, a near 4 to 1 ratio. But they all conform to the British 200 watts and European 250 watts average power used legal definition, which of course is not the power output.
