I guess that's all just based on consumer perspective though. Where as Bosch are a huge automotive supplier (60%) and many other things. Obviously best known globally for making the most horrible switches and displays for ebikes.When I think about Bosch, I think of washing machines, drills & lawnmowers, not EMTB’s
Kawasaki are Kawasaki heavy industries who make massive ships, planes, defense equipment and dabble in engines and motorcycles.
Honda were primarily motorcycle, then car and now do robots and jets - Honda would be the interesting one if they did make an EMTB from the ground up especially after they stunning DH bike.
Like many of these things they get convoluted. Yamaha motorcycles is a separate company from Yamaha. Not sure which part makes their bike motors and bikes though. They're the worlds largest producer of Pianos. But make all sorts of music equipment, jet ski's, golf buggies, skow mobiles, out board motors, robotics and so on.
