I've ridden my Chinese Cargo ebike for about 32 miles in Brooklyn this week.
In temperature in the 40 degree F, battery got down to about 70% from 100%.
The 20" fat, treaded tires are really noisy on pavement, likely not the most efficient; they also make handling of the bike rather sluggish, not very precise reaction with steering input.
PAS is very powerful, even at level 2 out of 5, not many significant hills in my area, riding on flat terrain on pavement with PAS 2 I can easily sustain 15-17 mph cruising speed and accelerate to 20+mph quickly.
It would have been more enjoyable if weather was warmer, but with wind chill the temperature felt like it was below freezing.
Since I was still getting used to how this bike handles, I didn't want to push the pace too much.
Handlebar of this bike is really wide, like trail MTB wide, not ideal for inner city commute between car mirrors, I think I will change that out soon.
I'm also thinking about changing the tires to street oriented tread, maybe that will provide quieter ride, better handling & less rolling resistance; curious how much suspension performance I would lose.
Or maybe even convert the front end to 26" wheel/fork to make the front end have more solid feel without the fat tire. Fat front tire just seems to make steering sluggish & vague.
