Whats the typical watts/mile required for a 20 mph tops, 48v, 500 watt hub motor e-bike? I know theres many variables (weight,wind,flat). Just looking for base line number.
watts per mile typical for e-bike?

too many variables. and the most popular is watt hours per mile.I'm in canada so we use kilometres. My biking buddy gets 9wh/km my slow/light bike gets 20wh/km and my tank gets 30wh/km

Well, my bike while i'm going 25mph on my bike, averaging 22mph on flat land with no wind, I am getting about 17-20 wh/mi.
If i'm blasting about going 45mph, my wh/mile can range from 35-45 wh/mi.

Lots of the folks posting threads about their bikes in the pictures section will give watthours per mile for that bike.
My Ping 48V 10ahr batt provides 500W and I get close to 25mi with easy pedalling, maybe 400W Bafang. I weigh 180lbs, and cruise 20-22mph on somewhat level terrain. So, around 20W per mile 
My Lith-ion is a slightly stronger performer, 48V 10.5 provides 525W and will run 30 miles at 19-20mph in the hills with easy pedalling, C-lyte 408 maybe 500W; 17.5W per mile for it
(edit update: BaFang8Fun uses 17W per mile, maybe better)

thanks! I'm starting with a 16S2P A123 pack....so I should get about 10 miles.

I'm typically around 12wh/mi, but always pedal as if I weren't on an ebike. When we get a windy day - either cross wind or headwind, the figure drops like a rock. I'm lucky to get 25wh/mi when we get our 20+ mph headwinds. Ditto for hill work.

For the majority of the folk.. (not only E-S).. The average IN NO PEDAL MODE is 10-15Wh per km.
At 32kmh a 700c bike will do 10Wh per km and a 26" mtb will do 15wh
I verified these number ALOT of time and today i can confirm these number again!
A good efficient E-car will do 10x that consumption at 100kmh

The 700c bike is that much more efficient
I've personally found tyre seloections makes heaps of difference on a 26" mtb. Knobbly tires are terrible for both speed and efficiency. A good road tyre makes all the difference. I've got some smooth e bike tyres I need to try, both 2" and 1.5" width (26" rim). Will try to see how they compare.Similar threads
