I have a similarly priced model, but from a different brand. Some of the extras are definitely debatable, but convenient. A second battery, belt drive, Rohloff electronic gear box. A chain with a derailleur definitely does the job, but belt and Rohloff need much less maintenance and I’m bad at maintaining chains. Second battery is useful since we actually do trips that go past 50 miles.

So even if both are not strictly needed, this bike replaces my car. And it’s pretty bad at social signaling, most people don’t realize what the ride costs.
