808Wh battery and 100 miles of range. These two numbers track with each other and are roughly believable.

OTOH, with a battery this big, a generator powered by the pedals, and regen braking this thing has to be heavy. I'd expect it to weigh at least 80 lbs. More likely 100. The fact that their "specs" say nothing about weight suggests they're embarrassed about the weight.

My eBike is close to 90lbs, but it is a large cargo bike touted as a "small car replacement". It is close to a tandem bike in size with a steel frame. I'm so used to it now, but I live in a house and never need to carry it up stairs. It does mean that I need an expensive bike rack to support that weight.

I lived in an apartment with only stairs where I owned a light gravel bike roughly 20 lbs and an old mtb that was about 35, and my back really felt the difference between the two.

100 lbs would be unmanageable.

With a bike the size of mine, I don't think I would own it if I was living in an apartment. It's just too big even without considering stairs. It's long. It's wide. It's perfect for how I'm using it not in an apartment. Not every bike is a fit for every rider.

The point I really fell like I left out is that with that size and weight of the bike plus being able to haul 300lbs, the motor and battery combo is rated for 45 miles. Not once have I felt like I needed longer range. It's not that kind of bike. I use it for tooling around while shopping or leisure rides topping out at 35 miles. Even at 35 mile rides, by battery still has plenty remaining as I still heavily rely on my meat motor.
