Why fixed?

Pros:

* It feels different and interesting. It is a fun change of pace-- sometimes a 140 rpm change of pace.
* Coolness factor.
* It is a respectable end-of-life for old frames
* Builds confidence


Cons:

* It is somewhat more dangerous-- depending on the rider.
* Hills are not always convienent
* Energy is depleted more quickly on long rides.
* Not as fast as a geared bike
