Nope.
Let me put on my economics hat for a second (since I use my degree about twice a year these days).
Scooters operate in a different economic sphere. The real danger to bike shops are wives and children. Scooters compete with walking, taxicabs, buses, and ride share. All of these are essentially zero investment activities on the front end with varying degrees of flexibility - mass transit is cheap, per-ride consumption, but are fixed in route/time. Scooters, taxis, and ride share are more expensive but more flexible from a timing and route perspective.
Bikes compete with cars: some investment on the front end and ownership costs. Cars have less flexibility and also incur parking costs. Bikes will compete with self-purchased scooters (not Bird or Lime but the ones you can buy, own and maintain yourself.)
The reason that bike shops are in danger of children is that people spend a lot of money on bikes when they are single. But if they marry a non-biker, that revenue stream either stops or is greatly diminished quickly. Then children come along and there is not enough time. So mid-20's through early 40's you probably see a huge drop in bike shop spending that then kicks in as the kids are self-sufficient or divorces kick in (yeah, dark thought but let's face it, economists don't care about such things, just the facts.)
If I were a bike shop owner and I had money to throw around on lobbying and trying to juice the market, I would invest in the following:
Propose legislation to make Tinder, Match and the rest of the online dating sites more difficult to use
Invest in Trojan and other condom manufacturers
Lobby to make divorce easier to execute
Lobby to increase the cost of marriage licenses
Notice that scooters aren't on that list. Shops only compete with purchased scooters and in that domain as a shop, I'd probably start carrying a scooter line as it can be complimentary to the bikes I am already selling.
