At what point would you have standardized this rapidly improving category of product? Would you have frozen the interfaces around the time of the Dodge Intrepid[1]? Perhaps after considering that example you start to see the problem with standardization.

You hear the same think about electric bikes, and the argument has the same fatal flaws. Current e-bikes are massively better than what was on the market 3, 5, and 10 years ago. Standardizing them at any point would have been catastrophic, and we must assume that standardization now would also be catastrophic.

[1: That said, all cars are converging on the exterior shape of the Intrepid, in a process similar to carcinization among animals. Weird!]

It seems it's almost time to standardize an e-bottom bracket so that motors can be interchangeable

[jeffbee]

I can't imagine what experience could have possibly led you to that conclusion. Current generation custom bottom bracket motors from Trek from Specialized and from Bosch and from Yamaha are all radically different and some of them are way better than others and none of them are interchangeable.
