Level 1 (Single Trail Scale 1)

You can ride a bike and are happy riding on dirt roads with gentle climbs and descents.
The trails are comprised mostly of compacted gravel or solid earth with some flat roots and smaller rocks. The surface may become loose at times and periods of stand-up riding may be required to overcome obstacles.

Level 2 (Single Trail Scale 2)

You enjoy riding a single track that isn’t narrow or technical and you know the basics of body position and how to brake and corner safely. You enjoy riding in the mountains if it’s not too exposed or steep. You’d like to learn more to enable you to tackle more technical or narrower trails with roots and rocks.
Trails comprise a loose surface, as well as roots and rocks. Narrow curves and steeper gradients are to be expected. Readiness to brake at all times is required, as is the ability to shift your center of gravity on the bike.

Level 3 (Single Trail Scale 3+4)

You are comfortable riding on narrow single track with some rocks and roots and can proactively ride most trails. If the corners are too tight or the trail is too technical you are happy to walk a few meters, but you’d like to work on your skills to help you ride them.
The trails include blocked singletracks, hairpin turns and tricky traverses. Loose scree and slippery terrain comprise most of the trail. Good command of the bike, excellent balance, concentration, and controlled braking skills required.

Level 4 (Single Trail Scale 4)

You are comfortable riding almost any trail including steep rock sections, tight switchbacks, off-camber sections, roots, and narrow exposed single track in high mountain terrain. You have ridden in the mountains and are not intimidated by sustained, steep descents that include all these features. You know when it is better to get off the bike, but do not have to often.
Exceptional riding skills are required, such as the ability to independently maneuver the front and the back wheels, as well as perfect braking technique and balance.
