While I can see your conundrum, My POINT is, and always has been,
Keeping a bicycle a bicycle... Even tho, I ride an "Assisted" bicycle... at what point does "assist" become" a motorized bicycle, well
that IS, already established with the E-Bike laws.
Which I
strongly dis-agree with here in N America... Your numbers of 20 + watts per mile are almost the same as my numbers for using my E-Assist bike as a moped on the highest setting while I ride, witch, the cut off is 32Km/Hr. that is 20MPH..
It works out to 14watts per Km, or 22.4 watts per mile... Well... whenever I ride like that I am
always thinking I am riding a moped, compared to what I can do with my own power only...
Oh, my bike and me together
are 280Lbs...
My assist is just simply NOT enough to go up any hill without my pedaling, 350 watts hub motor just won't let me go anywhere without pedaling but flat ground. and, THAT is what an E-Assist bike should be.. IMO Assisting, NOT doing the whole job...
