My 2 cents
K2 is a ski company and they make great skis. Bikes however are not their sweet spot. Heck, I wouldn't even buy a snowboard from them personally. My suggestion would be to find a bike manufacturer and look at what they have in your price range. Fatbottomedgurl's post had a lot of them to start with. Good luck with your search.

Do not be too timid and squeamish about your actions. All life is an experiement. The more experiments you make the better. What if they are a little coarse, and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up, again, you shall never be so afraid of a tumble.
