I do hike/ride up some silly shit all the time. Nothin' wrong with that at all. You do get to scope things out before coming back down. Move some sticks and boulders. Boy this got off line. I seem to recall that the OP wondered why some one would chose to take a bike too heavy for the individual to ride up. The OP thought it would mke more sense to ride a lighter bike and perhaps take less difficult trails down. Might be a more enjoyable experience. It might. For some. Others all about the down
Debate? Bikes are made for riding not pushing.
