$5k-$7k for an e-bicycle?
Yes yes yes, I realize enthusiasts pay up to $10-15K for high-end frames and wheels, with full Campy gruppos[1], but eBike buyer's aren't CAT-2 qualifiers.
On a side rant, the price of bikes in general has skyrockted. With so much of the manufacturing happening in China, I would have assumed that the overall costs of bikes would go down and quality would go up since the 80's (when I was really into cycling in my 20's). But the opposite has happened: quality stayed roughly the same and prices went way, way up. (e.g., A Tom Ritchie frame went for about $1.5k in 1984, and that was hand-made.)

Then you can convert those to ebikes with kits that cost €500-800 depending on power of motor and range of battery.
That's what I did; I transformed a regular Btwin Rockrider bike to an ebike 3 years ago, and have now ridden about 10k km with it. Couldn't be happier. It changed my life.
I used to drive a (big) motorbike; it's now been a year since I used it; it just doesn't make any sense to use a motorbike instead of an ebike for rides under 15 km, which are most if not all rides.
I built a second ebike for travel by train. Some trains have special "seats" for bikes but most don't, and they are in very limited supply anyway. But you can put a folding bike in the luggage compartment without a problem.
So I bought a used folding bike for €50, still in excellent condition, added a (low power) hub motor and a battery for €400, and I can go almost anywhere without worrying about finding a cab at my destination. It's exhilarating.
"Velosurance" is also an option for many with expensive cargo ebikes.
Ebikes are a pretty new technology with very little used market so far, but that will change quickly— I already managed to dig one up for 50% off MSRP last winter.
