I am considering alternatives for the Shimano Nexus 8 IGH I currently pair with a Bafang BBS01 mid-drive on a converted Breezer Downtown with horizontal dropouts. I was contemplating either Enviolo cargo or Shimano Nexus Inter-5e. Both appear to be stronger and able to take mid-drive torque. Are there particular issues with mounting the Enviolo? I seem to recall reading somewhere the action of shifting tends to pull on the hub which can loosen belt tension but my frame doesn't have a frame break to mount a belt and I don't want to use the Veer split belt so I would use a standard chain and sprocket. All advice much appreciated.
