im thinking of buying a full suspension GT I DRIVE FOUR 3.0.
How are these bikes for us big guys when riding? im worried of a bunch of "bounce" when
riding straight terrain
The forks and wheelsets are not quality, but other than that it's OK. Nothing fancy, but they can get the job done. The leverage ratio isn't "perfect" for clydes, but if you are under 280# you will be able to get the sag set correctly with no worries. The suspension design itself is relatively efficient...meaning the design minimizes any perceived "bounce" (bob,etc) from the suspension, for the most part.
