Apart from the motor and a straight handlebar the bike pretty much fits into the gravel bike category, which is doing extremely well at the moment. Those are rather versatile bikes, which one can use for anything between commuting, bikepacking and not-fully-competitive road racing. At least the mid-range bikes in this category are already out of carbon. It's far more common than exocitic nowadays. The price of 4500$ actually doesn't feel too excessive, given that a Specialized Diverge with similar components is 3900$ (https://www.specialized.com/us/en/diverge-comp-carbon/p/175285 https://www.specialized.com/us/en/diverge-comp-carbon/p/1752...) - without a motor. But ok - Specialized is also one of the most expensive brands. I bought a gravel bike this year (Trek Checkpoint), and I'm very happy with it. If I would have a strong use-case for an e-bike - like a longer commute - I would definitely consider something like that Prolog.
