That's why appearance is so important if you want to broaden the appeal of electric bikes....... so many people see bicycles as a fashion item or a symbol of sporting prowess and therefore see electric bikes as for the old, unfit or uncool. .......
Mainstream bikes became cool with the advent of the mountain bike and, more recently, the poularity of sportive events for roadies. There are plenty of MAMILS (Middle Aged Men In Lycra) out there with money to burn who might appreciate the option of a cool e-bike.
So many e-bikes have the battery in front of the front wheel. This extends the frame's rear triangle and shouts two-wheeled invalid carriage. It will be anathema to many cyclists because a narrower clearance between the rear wheel and the seat tube corresponds to a sportier bike.
Similarly, a nice curvy chain guard only appeals to a small number of conventional cyclists. A small proportion of these will want an e-bike. So, this design feature will appeal to a very small number of people.
The industry may not be able, or want, to reduce its prices. But it can make its products more appealing.
P.S. The point made earlier about using quality components is also very significant.
