Range not as good as friend's on similar Bosch motor

Doesn't matter what type of bike, applies any time one is riding behind the other.

Just can't see it making any significant difference at the slow speeds the MTB's normally go,

They are e bikes, what speed were you averaging 5mph?

Your 3 miles of headwind versus his 3 miles of downhill coasting could be significant, as could different battery capacities. Tyres and pressures too.
Lots of variables!

Not scientific research but on yesterday's ride which was essentially an out and back 22 miles, 11 miles against a very strong wind and 11 miles with, the increased power consumption against the wind was very noticeable, and way above my average. Also on the fast ride back with the wind, speed was above the cut-off for long periods of time, so no power was being used, whereas on the outward leg power was being applied at some level more or less continuously.

If you had bothered to read rather than jumping in with both feet you would have known I wasn't riding, but hey why worry about facts getting in the way. But for information my average ride speed is between 9 & 10 mph, hence why I doubt that drafting will have much effect at that speed.

Of course it will about 45% of the power you put in at that speed is overcoming air resistance.

I will bow to your better knowledge

Not that I want to be pedantic! but, 500w! On the road? naughty

Is he not referring to the battery?

500wh is refeering to the battery....motor is 250w

Little known fact - some of the first Bosch eBike motor prototypes were actually modified Bosch Rotak LI lawnmower motors

Ok, I didn't say it was an interesting fact...
