I don't think there is a Michael Dell for E-bikes currently. Not in the US or Canada.
....
If anything, there could be a knight in shining armour, on his white E-bike in Europe or Asia . They accept cycling as a true form of transportation, truly. Let's hope we get an E-bikewagen of sorts, priced right. There is a market there, socially acceptable.
There is no Michael Dell, and there isn't going to be. Not in the US/Canada, not anywhere. For several reasons:
1) If such a knight appears, then - as noted by others - the design will be taken over by zillions of Behemoth manufacturers in Asia. Not always "bought" but very often - copied. Easy to do, since a) there are little to none details to patent/copyright, b) patent/copyright doesn't seem to deter copycats in Asia, and c) the knight himself would be only too happy to provide blueprints and engineers to begin manufacturing in Asia. They won't have to buy him out - he will sell out.
2) Despite bikes being a popular form of transportation in Asia (mostly "bikes", not "ebikes", and not same popular in Europe), it is not likely that major technological breakthroughs will come from Asia. Hasn't happened so far, and would be against the very spirit where diligence and persistence are valued above creative thinking, and immediate results - above talents.
3) There is no universal demand for ebikes like there is for PC/laptops because there is no universal functionality. There is also no universal hardware.
OTH, different users can use same model of PC/laptop for either school, or work or entertainment. They now marketing different models for business, gaming, college etc, but you can still use same model for all of this - or upgrade the components like videocard, RAM, SSD.
The bottom line is, - you can't really compare ebikes to computers, they are 2 different phenomena. Hardware, software and accessories of computers are highly interchangeable. Ebikes have no universal software like Windows, a firmware of a motor is hardly an equivalent in complexity and functionality, it's not a standalone product and is not interchangeable with other brands motors.
Different uses, different structure, different times. Mostly - different times. Remember IBM computers? Many people already don't. Was a good product, seemed like it was going to be there forever, and then it was suddenly no more. (No, they didn't go bankrupt).
Most viable/reliable business model for ebikes, IMO, is "Lego". Interchangeable motors, batteries, connectors, displays. This all is already there, and A LOT of popular ebikes are assembled of such standard parts, only frame varies. Bafang dies, no big deal, replace it with some other "kingfang", "quickpower", "goldmotor" etc, like you do with RAM, SSD, keyboard.
Btw, I don't like Dell - had their PC once, it would only accept a certain brand of HDD
