This does not even require an app. Simply lock down all hardware and make it economically unviable by charging 100+ euro for a 5 second "software update", which you need to do if you ever unplug the battery for > 10 seconds. See the thousands of Accell bikes (mostly Sparta branded) on dumps. You can get them going again but that's only for diehard hobbyists and requires custom hardware.
