I am looking at a good starter mountain bike, in about the $500 range. The two that have been recommended to me the most are the Trek 4500 and the Haro V4. I have found a good amount of information on the 4500 but not much on the V4. From what I've heard is that Haro mountain bikes are a great value. Does anyone have any experience with Haro bikes and which bike is the better bike?
