So I am a completely noobie when it comes to bikes but I've done some research and I've got two choices in mind.

I will be using this bike to ride around doing errands and might even try biking to school which would be about 10 miles each way. Also I want something I could take on a light trail on the weekends. Also I live in Los Angeles so the roads are pretty bad. So I don't think a road bike is for me and these are the two bikes I have in mind:

The Gravity Zilla: http://www.bikesdirect.com/products/gravity/zilla.htm

or

The Gravity Liberty CDX: http://www.bikesdirect.com/products/...iberty_cxd.htm

So which bike do you believe would suit me better? Also if there is something better out there for my price range, $4-600, I am open to any and all suggestions.

I've been lurking around I know a few members here have bought either the Zilla or the Liberty CDX so if you guys see this and don't mind I would like a personal thought on the bikes.

100% honestly biking is something I believe that I will do a lot, so I do not want to buy a cheap bike where i have to replace it in a year but at the same time I don't want to buy a $1000 bike, in case I don't end up biking as frequently as I think.

So in short HELP! Hopefully I can decide soon on which I choose and get on the road
