I weigh 75kg (165 pound), am reasonably fit, only ride off road, and usually in pretty harsh conditions. My Bosch Performance powered mtb with it's 400wh 11ah battery gives me an average range of about 25 miles using a mix of eco and tour.
A recent change to Hutchinson DZO tyres has seen this average drop though.
I have also been known to almost flatten the battery on the bike in 10.9miles though, using eco, tour, and one very short blip of sort. The elevation gain was 6,362'
