I'm not necessarily convinced that this is true (at least not the terrible)
Compared with a well maintained chain drive it is likely to be of lower efficiency.
However, we're focussing here on low maintenance. I'd sacrifice 5-10% efficiency at "optimum" for the sake of what promises to be virtually zero maintenance.
I cannot imagine that my chain line is sufficiently well maintained to provide optimum efficiency, so I'll actually be losing less than the 5% quoted.
- shaft drive (Failing that a single/fixed/hub with complete chain case)
- enclosed rear brake (drum?)
- dynamo hub with mechanical disc brake at the front *
- LEDs powered from the dynamo
* Yes this is probably higher maintenance that some other options, but:
- I wouldn't sacrifice the stopping power of a disc up front
- The hub is going to mean no thinking about lights ever
- All the maintenance in on the "easy" wheel
Possibly most important though - A garage, or other DRY location to store the aforementioned vehicle
