This is pure fantasy stuff, theory which simply isn't practically realisable for e-bikes. I could quote endlessly such announcements which never reach fruition. Tell me when some product arrives.
We know nothing of the sort, the advances in lithium batteries have been slow over the last two decades. Small reductions in weight but size is still a problem. The main gains have been in safety rather than in performance for long life cells, for example today's compound cathodes far safer than the equal performing cobalt cathodes of yesteryear. But even for that gain we went backwards for a while in the mid 2000s with manganese cathodes failing to deliver adequate current rates and cells failing at as little as three months.
And other technologies only produce excited announcements rather than actual product. As I so often remark, the most common high discharge application in the world, starting vehicles, is still being done with the oldest technology, dating back centuries rather than decades. So much for progress.
.
Even if mentioned technologies were not being used your point is irrelevant. I was merely pointing out the technology to greatly reduce size and weight of motors and small drive trains with massive reductions already exists.
EPO / Blood transfusions,/ Human growth hormone etc etc are not common in normal life, it didn't prevent Tyler Hamilton with help of Spanish doctors make full use if them..
There are even lighter batteries coming into use including lithium air , lithium polymer is already with us and no doubt others will be coming along. However I doubt we will ever see any if these used to start our cars, or motors such as Siemens have developed in them euther . We will see them in places requiring their use and justifying their cost.
Because you can't imagine their use hardly means they will not be used.
The traction drive mentioned is already used, extensively in high end motor industry.( Look at the story about Rotrex superchargers)
Siemens motor is already in prototype aircraft.
Like I said the technology is already here to miniaturize ebike components way below their current size..I suspect its already going on. You don't think so. No amount of posts will change either opinion.
Had someone explained in a bar over a pint all I read in Tyler Hamilton,s book about his relationship with LA , his time in Girona and the depth of their cheating I would have said it was nonesense. We all now know it wasn't.
Mechanical cheating is going on. This recent incident proves it.
