Yesterday, I posted a question for advice on a first mountain bike on a budget (<150 bucks). I do appreciate all the advice greatly and as a result, I'll be checking around for used bikes at LBS's and Pawn shops, but just an FYI for everyone...I will NOT be riding down hills, doing stunts, wheelies, racing, or anything else flashy. I will riding straight ahead on a finely crushed gravel trail. This is simply something I want to do for exercise. I couldn't give 2 craps about tricks. I don't know if that changes anyone's opinion on what requirements are truly crucial for a beginner, but I've got a friend with a K-Mart Huffy he's had for 3 years. He rides the same trail I'll be riding about once a month (10-20 miles each time) with the same intention (exercise), and he hasn't had any problems at all. Would a Schwinn Sidewinder, Mongoose EFX, Mongoose MGX, etc. not get me started? Is more of a bike up front, until I found out if this sticks with me, not potentially overkill?
