The Concept


The German Single Trail Scale is among bikers a long-standing and proven reference point for the classification of the difficulty of trails downhill. We have been evaluating difficult and technical passages over and over again, even in uphill. Only those who are not permanently overtaxed on the trail will find themselves in the flow. The uphill scale gives handy tips for the next ride and helps to experience the pleasure of flow first hand at every level.

Uphill Scale

U0↑ (quite simple)

U0 describes wider trails on which no remarkable difficulties are to be expected. In addition to forest paths, wide forest and meadow paths with a good grip on the ground are to be expected, which can be driven smoothly and have hardly any obstacles.

The gradient is usually less than 20%. No special driving technique is necessary. With a classic mountain bike S0 presents itself as a medium trail.

U1↑ (simple)

U1 trails can be slightly narrower and have smaller obstacles such as flat roots and small stones. Loose ground, coarse gravel and water channels are to be expected.

The gradients are up to 25% and curves can be somewhat tighter. Riding technique is no longer trivial here. Basic knowledge of driving technique, especially starting on inclines, is required.

U2↑ (moderate)

On U2 trails, slightly larger roots, stones and steps of up to 20 cm must be expected. The paths are often narrow, can have 35% gradient and more, as well as inclination. The subsoil becomes more demanding due to loose material, coarse gravel, rock passages and water channels. Narrow bends are to be expected, but not hairpin bends.

More advanced riding techniques, such as lifting the front wheel briefly and overcoming obstacles by shifting weight, as well as a measured use of force, uphill braking techniques and good pedal management or short cranks are advantageous. The saddle should be lowered slightly.



U3↑ (difficulty)

U3 trails can have obstacles that make an obvious line and pedal management very difficult. There are more demanding passages with unexpected roots and heels, boulders, loose scree and diagonal rides on narrow paths. Also steps up to 35cm. These obstacles are also to be expected in tight curves; hairpin bends are not defined under upS3.

The gradients can be up to 50% even on longer passages and have flat stairs. A rock-solid advanced riding technique is a prerequisite. Raising and shifting the front wheel, weight shifting and targeted acceleration and braking to overcome obstacles are just as much a prerequisite as very good pedal management and a clean spontaneous line selection. The saddle must be lowered significantly. Individual passages can only be mastered standing up.

U4↑ (very difficulty)

U4 describes extremely demanding uphills with rough root passages, large stones, rock passages and steps over 40 cm. Loose scree, narrow diagonal runs as well as very narrow curves and hairpin bends are to be expected, as well as difficult stairs and inclines of over 60%.

Passages in which the chainring and especially the pedals touch down are to be expected continuously. In addition to a well-founded riding technique, demanding trial techniques are required. This includes above all the ability to move the front wheel (Front Switch) and the rear wheel (Back Switch). Pedal management must be well timed always fit otherwise hardly a chance. Starting off on the mountain must be particularly skilful. Even standing under the known criteria. The saddle must be fully lowered for freedom of movement.

U5↑ (extrem)

In U5 passages, the difficulties mentioned above occur in combination and in sequences. Extreme steep turns to the limit of traction, very high steps, narrow hairpin bends can correlate with very difficult ground. Even with sophisticated trail technology, many tests are usually necessary before an up S5 passage is successful!

In addition, there are extreme difficulties in exposed terrain. Support levels are an important criterion at eMTB´s, but it is very difficult to synchronize them with the difficulty levels U0-U5. The dosage of the forces of the bike often correlate with the level of riding technique.

The better a driver drives, the more he wants to use power. Either in the form of maximum support level plus brake management or as intelligent mode a la eMTB mode at Bosch or Trail at Shimano, for example.

Stefan

I have been deeply rooted in the bike scene for several decades now. As a bicycle trialer I was able to celebrate my greatest competition successes: many times North German Champion, German Champion, twice Vice World Champion and several times Team World Champion came together in the time.

I used these titles to ride many shows in all possible areas and scenes to be able to exist as a professional. Long-term partnerships with sponsors have developed as a result: Now Mondraker <25 years Giant> 25 years UVEX and soon 30 years Magura belong to it.

In addition, over the decades an enormous network of guiding and cycling techniques has developed on La Palma with Atlantik Cycling, which I can use very well for many activities. Currently the Supertrend eMTB with the motto #uphillflow together with Bosch eBike Systems and visionary Claus Fleischer gives me an unexpected tailwind to find new fun and passion in a huge dimension of cycling 2.0.

A weakness for mountaineering, photography and mountain biking shake hands. Since 1990 the playful aspect of riding technically very difficult trails has come more and more to the fore.

Julius Moosbrugger is one of the pioneers of alpine mountain biking in Vorarlberg. Inspired by Tyrolean friends of the Innsbrucker Vertridern he founded Xitrail in 2004. Today alpine mountain biking is well established thanks to better mountain bikes.  

Xitrail's code of conduct, which regulates the behaviour of bikers towards hikers and nature, is widely regarded as standard. Thanks to the heavy photo equipment it was only a small step to the e-Mountainbike. It soon follows that the E-Mountainbike opens up completely new dimensions.

If you like to stay in the Vorarlberger mountains you have probably already met Alexander Sonderegger. Either personally on any mountain with a mountain bike on a demanding trail with the touring skis in a via ferrata or just on foot.

Or certainly on the internet portal "Tourenspuren" which Alex has been running since 2007 with a lot of meticulousness and fervor in order to present numerous ideas for unforgettable experiences on the mountain for every taste. His special love is mountain biking in all its facets. At the beginning on the BMX and then at racing speed up the mountain later as a "Xitrailer" with the bike on the back to the summit and down on technically tricky trails. Always with a smile on his face. Rooted in tradition but always open to new ideas, the e-Mountainbike has quickly acquired its interest and favour as a fully-fledged mountain bike of the first choice.
