- You are inventing a complex mechanism where none is needed. Those who have no
- interest in "swapping gears" are generally quite content to ride a single-speed
- bicycle. Casual riders generally buy their bicycles at department or discount
- stores. Your mechanism would not only have to make the simple task of shifting
- gears idiot-proof, it would also have to be able to be manufactured for less
- than a $15 derailleur in order to find it's way on bicycles used by these
- riders. If 15 minutes of instruction can save about 20 pounds of gizmos, why
- invent the gizmos?

- I think that Richard Engelbrecht-Wiggans was right when he described the
- Sturmey-Archer planetary gear hub as the solution for those who really want a
- simple, reliable commuting transmission. The problem is, as Richard points out,
- the casual rider thinks that more gears will make him go faster without doing
- any work.
