I have a felt vault and it works great for a beginner bike but I'm giving it to my one of my son's to replace a mongoose. So I want a new complete under $600. The only brands I've looked at are wethepeople and fit. It seems like Fit gives more bang for the buck. But I really have no clue what I should get. I will be riding parks mostly. I am a beginner but I don't want a beginner bike. I want a bike that will take me a while to catch up to in skill. Any ideas will be appreciated.
