There have been a number of motors like this in the past but none have stayed the course, and I doubt it could challenge the Bosch, Daum or Panasonic ones. The Swiss company BikeTec who make the high quality Flyer e-bikes used to have a motor like this as you see in the photo below of their F model, but they dropped it in favour of the Panasonic system for all their models.

Frank, what's the advantage of this type of motor? it's heavier than the 250W Bafang, more expensive, lower efficiency etc?
