    Why bike part manufactures doesn't make robust ebike specific drivetrain parts?

    Why bike part manufactures doesn't make robust ebike specific drivetrain parts?

    Middrives are very popular now days and it made me wonder why Shimano/Sram etc. doesn't make proper really robust drivetrain parts for ebikes? Wider rear sprockets, chainrings and chains.
