I am somewhat new to the mountains of Montana and my interest for mountain biking is through the roof and need some advice on going in the right direction when it comes to bikes... And I'm currently bike-less. I'm 27, 6 feet tall, skinny but fit, and I eventually want to be able to climb trails for hours on end once spring comes back around. Now, I'm on a budget and I've done some browsing at pawn shops and totally saw the risks involved there. I also saw some decent "looking" bikes for cheap at Target. Am I wasting my time at a retail store or at a pawn shop? Or should I wait for the right, awesome bike at a bike shop? Craigslist for a solid brand bike maybe?
