Trekx M136 Bicycle The bicycle was used very little, but it stopped for 4 months in a place that does not get sun. I adjusted the gears and changed the original rear Shimano gears. The front one needs changing. Other than that, the bicycle is in excellent condition, no dents or falls, and it's lightweight for mountain riding. It comes with a Trek safety rope, size 27. Its new price is 1600.
