Couple more questions....
What's the approx range fully charged?
Does it stay strong until the battery dies? Or does it wane somewhat as battery runs lower?
Have you had it die while you're out and have had to pedal? Is it a beating to pedal at 54 lbs? Or not bad?
The original battery was 500wh. I would average approx 1% of battery per kilometer. But in reality I would expect around 60-70 kilometers of range out of it. I think my longest ride so far was 61 kms all flat, sunny day, no wind and I had over 50% left using assist very frugally.
Factors that affect range are rider weight (I'm 215lbs), additional cargo, headwind, hills, and the amount of assistance chosen. The bike has 5 levels of assist, and those levels are individually adjustable in a mobile app.
The new battery is 800wh and I average approx 1% of battery per 1.5 kilometers, which makes sense considering the battery is about 60% larger capacity. I could expect 100kms I suppose.
I have never run out of battery TBH. I run out of gas before the battery does. The assist levels stay consistent as the battery drains until you get below 10% or so, then the bike only offers the lowest assist level. I have never experienced that though.
Without question, and even though the drive train is a standard bicycle setup (10 speed), it is a beast to pedal it up a hill unpowered. I had a similar Giant Fathom E+2 hardtail that I sold to a work buddy. He ran the battery dry on one ride and had zero fun getting up a steep hill with it. He now packs a spare battery for long rides.
BTW, many ebikes have a throttle which basically lets it run like a motorcycle. A throttle is common on an ebike with a hub drive on the rear wheel. A throttle is rare on a mid drive ebike, and mine does not have one. You go nowhere without pedaling.
There are some lighter weight ebikes now, and some of the more road/gravel oriented ones are easily pedaled without power. Tire choice makes a difference as well of course.
