You are wrong Lowell.
It is not useful for you, but for most of bikers it is useful. The less power you need the more useful it is as you dont need spend a lot of money for powerful battery pack.
Where will the average person buy this kit that doesn't exist? If there was such a demand for dual chain gear reduced ebikes, someone would be building kits to take peoples money.
So there is either not enough demand, or it's too complex and expensive to build and not profitable. The fact that the copyright holder ( ) has never put any ebike products into mass production pretty much sums up the commercial viability of the idea.
