How about this? This ebike here is VanMoof, a Dutch company.
These things are mobile connected, do use cloud services (no kidding here!) and can be unlocked via cell phone.
VanMoof is now bankrupt, so the servers will probably gone away soon. So there's now only a small time window left for owners of such a thing to copy their encrypted keys from the servers, normally used to unlock the bike, in order to be able to still use them.
So even while owning the bike, if the company should go away, does not any longer mean that you can use it.
Dutch e-bike maker VanMoof has been declared bankrupt and administrators are considering whether it can sell assets and restructure to save the business, the company said on Tuesday.

I mean if Tesla ever would go out of business, it will be probably the same there then.
