When the AK-47 is discussed as an object or a "design" what people seem to consider most important is it is a "low-tech technology". The design optimizes, to the exclusion of all else, being cheap and easy to manufacture & easy to service in the field by its user. Modern ebikes are standardizing on the opposite of this. Ebikes seem to usually contain multiple microcontrollers running proprietary code and proprietary connections to batteries—made by startups that will not outlive the ebike itself
