Buying my first bike!! :D

[walidch]

Hello guys,

Posting from Beirut - Lebanon.

I just learned biking and I love it. Such a complete freedom.

I'd like to take the next step and buy my own bike now but I am kinda confused between the following, any tips could be very useful:
Trek 820 (model 2010)
Giant Upland SE
Specialized Hardrock (model 2010)

The Trek is the lightest and seemed VERY stable on the ground.

I will be using the bike to get to work, and maybe go for a ride in nature (it would be a little bumpy there).

My budget is around $400 and all of the above are within budget.

Thank you all
