I recently received a K2 Cheyenne from my aunt for a present, but when I looked for it online I did not see any information for it anywhere. Anyways, I am able to return this bike to the department store and get cash back for it in which I can buy another bike from somewhere else. I was actually not really looking to spend much more than 350 on the bike (K2 was bought for 200) so I was looking at the '04 Giant Rincon and '04 Trek 4300? Is it worth returning my K2 or should I get another bike? The Trek is $319 and the Giant is $339. Any other bikes I should look at? Btw, I am a newbie rider looking to get into biking. Any thoughts would be greatly appreciated! THANKS!
