Is this bike worth getting for $450? I primarily going to use it for daily commuting and exercise. Not really interested in the whole track or fixed gear scene other it'll give me a better workout. So is it worth it?

Also if I end up not liking fixed can I switch out the fork to one with a front brake eyelet so I can install brakes. Also what else would I have to buy if I decide I want a freewheel?

Thanks!
