In the Netherlands at least most of the established brands (Gazelle, Sparta, Batavus) have been selling e-bikes for 15-20 years now with sales really taking off in the last 5-10. Most are comfortable city bikes that use standard bike parts. Battery performance has improved a lot over the years and most models allow you to remove (and replace) the battery.
Depending on where you live they may be sold under different brand names. I saw that Sparta is for instance sold as Hercules in Germany.
€2+k would be a Golf-class e-bike. A decent non-electric bike is around €1k, add to that the battery, motor, display, charger, etc. and you get to €2k quickly. High-end e-bikes easily go for €4-6k.
I believe another term related to these phenomena is Elephant Paths. Named after the trails that pedestrians leave behind when they choose a shorter path over grass in favor of the official paved paths.
I recently listened to an interview with the editorial team of Deadliest Catch (Art of the Cut #51). I could see this product being used by similar media productions where thousands of hours of film footage is generated in remote locations with low uplink speeds. Instead of shipping the drives all the way to the post-production house, the drives could be ingested at the nearest AWS facility.
