At least in Euro-ville, 60% of all new bicycle sales are eBikes. I can't find a solid figure for the US, but based on the growth of a few name companies that can't keep up with the orders I suspect that's a shift here, too. The industry word is that ebike growth is exponential and motorcycle sales are in decline. If you do a Google search on "motorcycle dealers closing" limited to the last year only, you get a depressing number of hits; including insider stories about how motorcycle imports and exports are slowing up practically everywhere. These are interesting times. That “change” thing is proving itself to still be a constant.
One of the funniest things I've read about this business and customer shift has been from traditional bicycle shops who imagine that repairing eBikes is "different" or more complicated than fixing a motorcycle. Current breed bike shops often charge as much as $50-80 to swap out an ebike tire, especially a back tire on rear-hub driven models. eBike repairs are different than motorcycle repairs, for sure; about 1Mx easier. Anyone who can troubleshoot fuel injection or electronic ignition could do anything necessary on an eBike without any training at all.
