A trials bike is built short to allow maximum maneuverability and tough to allow the rider to perform stunts or jumps. I built a trials frame using other bike frames for parts. Essentially I made the existing frame much shorter, removed the seat, and reinforced it with braces and wraps. The direction that the rear axle enters the frame was also changed to accommodate a single speed setup; this allows the chain to be tightened. I now own a very nice well-built chromoly trials frame for less than I could buy one. Customize Description I cut a used mountain bike frame into pieces and then welded it back together in the form of a trials frame. Essentially I made the existing frame much shorter and removed the seat. I started with a large frame so that I would have a long wheelbase. I reinforced the frame by the front fork and by the rear wheel. The direction that the rear axle enters the frame was also changed to accommodate a single speed setup; this allows the chain to be tightened. This involved welding in a new brace and cutting out a new wheel path.
