you are comparing apples with pears!! The DJI motor etc is not standalone, it has to get fitted to a bike....meanwhile all the leading/volume brands are already committed to Bosch or Shimano etc. Hence the market share for bikes with the DJI system is very small and until/unless anything other than Amflow or a niche brand decides to adopt it .....it is not a key competitor for Bosch.That’s what Panasonic used to say about Samsung back 2008.
Now people say “Who’s Panasonic!”
