Hi everyone, I'm interested in buying my own fixed gear bicycle.

I looked into buying a bicycle and found this :

Fuji Track Fixed Gear Bike 2015

I love everything about it, however, I want to know if this is a good bike to begin with.
A flip flop hub from what I researched would be nice, so I was also wondering if it is possible to place on on the bike, and how much it usually costs.

Thank you,
