Given it's own thread - continued from - mid drive hub motor advantages?
In a way ... I must agree ...
Human power?
According to "NASA 1964", a "Healthy man" is capable of:
About 200 watt sustained for 30 minutes
About 150 watt sustained for 60 minutes
100-150 watt seems a reasonable sustained "human assist" on an eBike! ... ?
I, personally, would like to sub-categorize "eBikes", into 3 categorizes.
1. eaBikes - electric assist bikes
<750 watt output motor ?
Healthy man is capable of sustaining 20%, or more, of the eBikes propulsion
2. eBikes - electric bikes
>750 watt output motor ?
Where healthy man is capable of reasonable contribution - but, essentially, only during limited throttle use.
Due to wind resistance, a tucked position increases range, better than a "proper" pedaling position.
Somewhere near 30 mph, the cyclist, (<10-15% contribution), is detrimental, to speed and range, compared to a more aerodynamically positioned, (non-pedaling), rider.
3. eMotorcycle - incapable of any "reasonable" % pedal assist
Pedals are "ornamental", if they even exist!
Note: 750w (watt) = 1hp = USA, Federally recommended, eBike limitation.

All those numbers are fine, but most lack a 0 at the end to make any Ebike interesting to me.
When you start feeding 10 times human power, which I consider only the beginning of interesting performance, a bicycle drive train is not very long to show its limits.
