Some background on Bending Spoons: Their business model is to buy struggling companies with a bigger userbase, that have financial problems and then they are laying off most of the devs and try to take out as much money as possible by making the product as horrible as possible. They did it with evernote, they did it with WeTransfer, they did it with Meetup and they totally will do it with Komoot
I did some research a while ago: There are a lot of conversion kits around for foldings bikes. Most kits are just replacing your front tire with a motor hub and that is of course also available for 16" or 20" wheels. AliExpress is full of them. Amazon has them. A ban on unsafe electric devices would be the more sensible way.
