I understand what your saying, but it would be best to take the bike back and ask for your money back, then buy a magazine and look for a bargain in there.
Right at the moment they are off loading 2002 models because 03's are coming out.
I say this because my first bike came from Toys r us and I thought it was okay.
when I got it home the brake pads were missing,
then a chainlink jammed whilst riding,
then the bearings in the crank gave up the ghost,
the pedal apart and the tyres lasted only a couple of hundred miles before they had to be changed (i'm talking 300miles max).
I could go on but eventually I did what I recommend you do and since buying a good quality bike on sale I've had no trouble.
Believe me the bike is going to be trouble.
