Questions
Did the power assisted three wheeled vehicle (bike with engine) come before the car?
Does the one wheel at the front predate the two wheels at the front?
Which is more stable (at speed)?
If so, and car technology evolved from bikes, does this mean that e-bike technology is being watched with interest by car research and development companies, or are the two markets completely separate now?
Sorry, not normally that quick.
Question one doesn't really apply as it wasn't a bike with engine. The very first IC motorised vehicle used wagon parts, three cartwheels with one at the front. It's scale was more like a traction engine than a bicycle.
So in answer to question two, one wheel at front of course.
Question three. One wheel at the front has a better record from the stability point of view but both have severe though very different disadvantages.
Question four. The markets are completely different now and I doubt the motor industry would give the e-bike one a glance when looking for progress. Two of our best known e-bike motors were created by the motor industry in fact so it's very much the reverse. Following the Arab oil crisis of the 1970s both General Motors and Chrysler started looking at alternative transport forms. From GM research Edwin Currie had a bicycle motor idea and created the Currie Electrodrive rear wheel spoke attached motor that we know to this day.
Meanwhile Chrysler developed the motor that we now know as the BionX, abandoning it somewhat unfinished, hence the need for the rider to keep selecting the power and regen modes. It would have been good if that could all have been automated, but the Canadians who now produce it are happy with it as it is, and it's certainly a good product.
And of course our lithium batteries and in particular the Li-polymer ones result from electric-car battery research.
