Which is a better bike to get for someone new to trials and urban riding? Both are in my price range but the trek is $100 cheaper than the kona in most of the local shops. I hear great things about both bikes and I hear the trek frame is bomb proof. Can anyone give me some feedback on both of these bikes? I'm mostly concerned about the frames, because with my size and weight I'm sure to break parts anyway so it’s the frame I need to hold up the best.
