Backcountry adventure, panoramic ridges & self-sustained pedaling.

Minimal or zero uplifts (pure pedal-powered “Eco/Trail” mode).

1,800 m – 2,200 m+ of sustained endurance climbs & battery management.

STS S1 to S3 (flowing woodland paths, natural traverses).

For endurance-focused riders on modern Trail/All-Mountain E-bikes (130–150 mm) or light E-MTBs.

S0 (Very easy)

S0 describes a trail that presents no particular difficulties. These are mostly flowing forest and meadow paths on grippy natural ground or consolidated gravel. Steps, rocks, or root passages are not to be expected. The gradient is gentle to moderate, and curves are wide.

• Trail surface: Firm, grippy ground (hardpack, consolidated gravel)

• Obstacles: None (no steps, rocks, or root networks)

• Gradient: Gentle to moderate (up to 10%)

• Curves: Wide

• Riding technique: Basic bike handling and controlled braking

S1

S1 describes a trail where riders must expect smaller obstacles such as flat roots and small stones. Isolated drainage channels and erosion damage are frequently the cause of the increased difficulty level; the surface can also be partially unconsolidated. The gradient reaches a maximum of 40% (22°). Switchbacks are not to be expected.

From S1 onwards, basic riding skills and continuous focus are required. More demanding passages demand modulated braking and dynamic body weight shifts. Riding should generally be done in a standing position. Obstacles can be rolled over.

• Trail surface: Partially loose ground possible, small roots and stones

• Obstacles: Small obstacles, water channels, erosion damage

• Gradient: < 40% (22°)

• Curves: Tight

• Riding technique: Basic riding skills required; obstacles can be rolled over

S2

At difficulty level 2, riders must expect larger roots and stones. The surface is frequently not consolidated. Steps and shallow stairs are to be expected. Tight curves often occur, and the gradient reaches up to 70% (35°) in some sections.

Obstacles must be overcome by shifting body weight. Constant readiness to brake and shifting the center of gravity are necessary techniques, as well as precise brake modulation and continuous body tension.

• Trail surface: Surface mostly not consolidated, larger roots and stones

• Obstacles: Shallow ledges and stairs

• Gradient: < 70% (35°)

• Curves: Basic switchbacks

• Riding technique: Advanced riding technique required

S3

Blocked singletracks with many larger boulders and/or root passages belong to category S3. High steps, switchbacks, and tricky off-camber sections occur frequently; relaxed rolling sections become rare. Slippery ground and loose scree are also frequently to be expected; gradients exceeding 70% (35°) are not uncommon.

Passages featuring the 3rd difficulty level do not yet require trials techniques, but very good bike handling and continuous concentration are prerequisites for mastering S3. Precise braking and very good balance are necessary.

• Trail surface: Blocked, many large roots/rocks; slippery surface, loose scree

• Obstacles: High ledges

• Gradient: > 70% (35°)

• Curves: Tight switchbacks

• Riding technique: Very good bike handling required

S4

S4 describes very steep and heavily blocked singletracks with large boulders and/or demanding root passages, frequently with loose scree in between. Extreme steep ramps, tight switchbacks, and steps where the chainring inevitably bottoms out occur frequently in grade 4.

To ride at difficulty level 4, trials techniques such as displacing the front and rear wheel (e.g., pivoting in switchbacks) are absolutely essential, as well as perfect braking technique and balance. Only extreme riders and exceptional mountain bikers can manage S4; even carrying the bike down these sections is often hazardous.

• Trail surface: Blocked, many large roots/rocks; slippery surface, loose scree

• Obstacles: Steep ramps, barely rideable ledges

• Gradient: > 70% (35°)

• Curves: Extremely sharp, eyelet-tight switchbacks

• Riding technique: Perfect bike handling with trials techniques required, such as rear-wheel pivoting in switchbacks

S5

Difficulty level S5 is characterized by blocked terrain with counter-climbs, scree fields and landslides, eyelet-tight switchbacks, multiple high consecutive ledges, and obstacles such as fallen trees—all often on extreme gradients. Little to no run-out or braking distance is available. Obstacles must partially be cleared in combination.

Only a handful of extreme riders attempt to conquer passages at difficulty level 5. Obstacles must sometimes be jumped. In switchbacks, wheel displacement is barely possible anymore. Even carrying the bike becomes almost impossible here, as one must hold on or even climb while walking.

• Trail surface: Blocked with counter-climbs; slippery surface, loose scree; the trail is more of an alpine footpath

• Obstacles: Steep ramps, barely rideable ledges in combination

• Gradient: >> 70% (35°)

• Curves: Eyelet-tight switchbacks with obstacles

• Riding technique: Excellent mastery of specialized trials techniques required; displacing the front and rear wheel is only possible to a limited extent

Optimal Months: March to June and September to November offer prime dirt grip, moderate temperatures, and dry trail surfaces.

Winter Operations: December to February provides clear coastal riding with mild seaside temperatures.

Rain Protocol (Plan B): If wet weather impacts high-altitude loam sectors (Melogno and Barbottina), guiding logistics immediately redirect to self-draining, porous limestone sectors along the coast (San Bernardino, Spotorno, Le Manie) where traction remains predictable.

Coverage: Personal accident and third-party liability insurance is not included in the guiding fee. Riders are responsible for having active sports accident insurance covering mountain biking activities.

Deposit: A €100 deposit is required upon booking, processed securely online via Stripe (accepts all major credit/debit cards and digital wallets).

Final Balance: The remaining balance is paid directly in cash to your guide on the morning of the tour before departure.

Base rates cover private group departures for up to 4 riders (5 riders for Monte Carmo 4×4). Additional riders up to the vehicle limit pay an individual per-person supplement. We do not combine unrelated bookings.

Personal insurance

Lunch: from € 18 to € 20 per person ( Part of the proceeds will be used for trail maintenance )

E-MTB Rental: Premium E-bike rentals are arranged separately via our dedicated rental page.

Specific E-Components: You must carry a spare derailleur hanger and brake pads compatible with your E-bike.

Train ticket if necessary

Battery Charger: You must bring your own specific battery charger in your backpack for the midday boost.
