try this site!! they have soo many bikes factory direct for cheap, they may not be the most popular brands but check them out, i bought a road bike from them and it was 500$ and very esily comparable to a 1000$ trek!
the bikes come dis assembled, but can be put togather with just a little bike experience! this websiet has the more high preformance bikes tward the bottom of the page. i highly recommend you check this out, the bikes are super legit too!
