Lemond Fillmore 08 vs Fuji Track 08 vs Charge Plug 09

A track bike is a bike that can be used on the track which could be a range of geometry. As long as the BB is high enough to be allowed on a track then fine. The Fuji doesn't come with brakes, has a track based fixed gearing and a higher BB than a road bike so to me would suggest it is for a track. Not sure why it needs to look a certain way?

I was mainly referring to the front fork and the bb height. That said, I can see from the picture that was posted that the bb is higher than I remembered.
