- For what it's worth, when I'm not racing I frequently ride for very long
- distances in a single gear. This has advantages for training (it means I
- have to pedal much faster under some conditions, which is a good thing for
- flexibility) and causes no problems in starting, climbing etc etc.
-
- Gearing does not serve the same function on a bike, because this is
- possible, but isn't possible for a car (not economically possible anyway).
- Gearing allows the rider to climb very steep hills, and maximise the speed
- for his/her power output in a racing situation. For commuting gearing is
- largely irrelevant beyond selecting a good all round gear to ride in, and
- historically this view has been reflected in a wide range of commuter bikes
- with one gear only supplied.
-
- Gearing of a racing type has recetly been appearing on non-racing bikes for
- fashion rreasons more than purely functional ones.
-
- Where does this leave automatic transmissions? I would suggest that it
- leaves them in the "Useless gimmicks to separate fools and their money"
- category.
