It depends a ton on terrain and riding style. I am 215 and got 12.1 miles on mostly pavement with 14% left in one direction to work. Top speed was around 15 mph. The other way, while it was warmer in the morning, it was more stop and go, and 12.3 miles and I almost had to walk-of-shame it the last 200 yards due to dead battery. It nosed up and I had to reset it and sit awhile then rode the last 200 yards. I think I was in mission at the time.
I get that sensor error sometimes too, but I am hoping it's my hiking style shoes causing my toes to lift as I lean. I also have had a couple nose dives, but it has been my fault- leaning too far forward on an uphill and ignoring (didn't realize what it was in time) the very brief pushback. The heavier you are, the easier it is to shift enough weight forward to overpower the wheel and eat pavement. Be careful, take your time, carve and have fun!
