There is an interesting article, regarding fixed gear bicycles, on the USA Triathlon site. The article is written by USAT Certified Coaches Mickey Cassu and Jason Norman.
Here is a excerpt from the article:
Using a fixed gear bike to improve smoothness in your pedal stroke.
"Use of a fixed gear bike will focus you on your pedaling technique as well as increasing leg speed and strength. The mechanics of a fixed-gear bike require you to pedal as long as the bike is moving forward. Inexperienced riders should consider using a fixed-gear bike on a stationary trainer for the first couple of rides."
