The mountain bike single-trail
Single trails are the most challenging route sections, particularly popular among bikers, which often go over rocks, routes and specially designed curves.
In order to allow for better planning, a scale of S0 to S5 was defined for mountain bike single trails in addition to the easy (blue), moderate (red) and difficult (black) levels of difficulty.
The scale is aligned to the average mountain biker with a bicycle the meets the current technical standards. Route sections marked S0 and S1 belong to the blue – i.e. the easiest – routes, whereby no special driving skills are required for S0. On a route marked S1, there are smaller obstacles such as flat roots and small stones. Moderately difficult routes marked S2 have hairpin bends that need to be turned and the roots and stones are already a little bigger.
The S3 to S5 levels of difficulty are assigned to the black routes. Very good mountain biking command is necessary on an S3 route. Large boulders, high steps, hairpin bends as well as driving on slopes in combination with slippery surfaces become a challenge. Special trail bike techniques are necessary for S4 and S5 – loopy hairpin bends with steps, extremely steep ramps, terrain with large boulders (S4) or scree fields (S5) are part of the standard.
