An ebike designed specifically for touring will not have hub motors, at least not for long, unless the tour is only in Holland where a street curb is considered a hill. It is obvious that ebikes have taken off in Europe much faster than the U.S. but that is simply because conventional bikes are used far more to start with. However, ebikes don't have to be complicated. An aftermarket center drive can be applied to almost any bike now using a BaFang. Build any bike and equipment combination and add a 750w center drive. 750w (1 hp.) motors only seem large because some idiot thought that a 250w motor would limit excessive speed around pedestrians. Where manufacturers in Europe have erred is in making a separate line of bikes that mount small under powered motors inside the frame. Why is this happening so much with their designs? Because they are all using someone else's poorly designed motors and building their bikes around them. A 500w motor isn't enough power for touring when riders are carrying more and more equipment to remain on the road comfortably for extended periods, let alone 250w or 350w motors.
