Our local bike shop is incredibly posh, it's a Shimano Di2 service centre and they stock (in no particular order) Bianchi, Focus and Orbea. I'd say about 50% of the stock is electric, and very little under 2k. But folk here are buying electric bikes like they would a second car (though very few commute). The owner is a nice bloke, but always confused when I come in, never buy anything, and only ask for bike boxes!
He won't touch anything pre 2000, he'll just say 'I'm fully booked for repairs', even if he isn't. They still build wheels, but the per wheel cost is eye watering. I reckon I've maybe bought a saddle off him, and a spare tube once when I punctured far from home. I mostly shop online. I used to feel bad about that, but I can save 30% on what my lbs charges and it comes to my door in 48hrs.
I have literally no idea how bricks and mortar only bike shops continue to trade. Even eBay is getting cut throat, and Amazon is absolutely killing even the bigger retailers like Decathlon. In Europe, there's still a fair distrust of buying online (which explains the 7 shoe shops in my local town pop. 50k), but sooner or later they'll abandon shopping for real.
There's a massive explosion of drop lockers and WiFi drop locations in Spain and France, for convenience it's hard to beat. You can pick up on the way to work or at midnight on the way home from the pub. There's a shop not far from me with 100+ top end Carbon frames sitting on the wall, a stock that has hardly shifted in two years. I really fear for the future of bricks and mortar, and it would be a real shame not to be able to rock up on a Saturday morning and have a chat with the mechanic.
I remember the days when you got a cup of tea and a biscuit at my lbs, and no pressure to buy anything (but of course you did!)
Perhaps that's the secret: make it social, cup of tea and a biscuit seals the deal every time!
