......This thing could have a front, mid, rear derailleur with a 2 speed in the middle, it could have more gears than a highway tractor. 3 in front x 10 in the middle x 2 x 10 in the rear = 600speed. My next thought was, "Just because you can doesn't mean you should." ?....
Any suggestions, knowledge to impart or experience to share would be appreciated.
As im sure you realise, many of those ratios would be duplicated..even triplicated.. so really you are just adding complexity, weight and maintenance issues.
Even a "simple" 21/27 speed bike gearset has many intermediate gear combinations that are effectively redundant .
And once you add power assist, the need for multiple ratios reduces dramatically.
Consider that most modern electric drive vehicles only have one ratio !
So figure what max and min ratios you need, add how many more you feel useful inbetween , and keep it as simple as possible.
