Maybe a little problem there.
I think I read you paid around $80 for the bike. I'm not being a smartarse, but I think you should be happy with how it is and use it as a beer bike. Save your money and look for another "aggressive" style bike.
BUT...If you want spend some money on that particular bike, maybe you should look at dumping the suspension forks and buy a rigid MTB fork. Next a good flat stem, and then a flatbar (or riserbar with a 20mm rise) I think it'd rock then. You could get those parts secondhand and save some money too.

This is mine with a 20mm rise, riserbar.
