Oh yes. Got an e-bike with a Bosch controller. Have to click away the app advertisement every time before I can use the bike. And the app requires registration. I have the strong suspicion that as soon as I do that, the bike will only work with my phone and start locking out my family members from using it.
Other way around. They'll try to upsell you on a 5 euro feature that locks the bike to your phone and prevents family members (or thieves) from using it. Though since almost no ebikes do that, it doesn't work to reduce theft.
Not much point in the app unless you want to transfer routes to a map app on the head unit, though.
Like with some cars, they then get sold for parts or there is a hack to work around it. I just put a gps tracker in the battery to get insurance money since the cops will do nothing (but will if you go after you own bike to stop you from trespassing).
My bosch ebike controller is a very lousy timekeeper, and the only way to set the clock is with an app.
