Compared to other offerings from other companies, it is actually a good price, analog gravel bikes with similar components go for $1.6-2k from big brands. Right now for $3K you are getting a Verve! (a hybrid bike fitted with low end components). People are paying 6K for a no suspension fitness bike with wide tires claiming that it is a high end bike.
While compared to motorcycles ebikes look notoriously priced, one should note that Just that battery+ motor combo probably costs over $1000 to the bike manufacturer so I can't agree with the $800 part of your comment. A comparison with a motorcycle should take into account that batteries and motors add quite a bit to the cost.
That being said, do I agree that overall ebikes from big brands are very overpriced? Yes, it is ridiculous, but what is worse is that you see many people going in an buying the most expensive/least functional bikes from big brands, thinking them like a car purchase (which they are not, these are still bicycles with integrated motor/battery) and bragging about it, claiming it is best of the best because of some brand fanaticism. Not to mention accessories, an aluminum tube with two springs is being sold over $250 which is a mediocre suspension solution at best.
We are living the dark ages of ebiking, I am hoping that it becomes more popular and we see much better products at reasonable prices.
If it is very hilly that is still a very good range for a 400wh battery. But as you said range depends on your riding habits.
Maybe you haven't ridden in high level enough to get an estimate, I will check this out next time I take it for a ride.
