Cube AMS Hybrid ONE44 C:68X SLX 400X – Ultra-Lightweight Carbon E-MTB with Shimano XT Di2

Experience the ultimate in electric mountain bike performance with the Cube AMS Hybrid ONE44 C:68X SLX 400X. This flagship full suspension e-MTB combines Cube’s most advanced C:68X® carbon fiber technology with cutting-edge electronic shifting and premium Fox suspension, creating an ultralight trail weapon that weighs just 17.5kg.

C:68X® Carbon – Cube’s Flagship Frame Material

Built with Cube’s pinnacle C:68X® carbon fiber monocoque using Advanced Twin Mold Technology, this electric mountain bike achieves an extraordinary 2100g frame weight – the lightest in the range. This premium material combines optimal fiber blends with nano particle-infused resin for unmatched strength-to-weight ratio. The Agile Trail Geometry ensures playful handling and confident technical riding, while the fully integrated 400Wh Bosch CompactTube battery maintains perfect weight distribution. PowerMore compatibility allows a 250Wh range extender for epic all-day adventures.

Bosch Performance Line SX Lightweight Motor

The compact Bosch SX drive unit delivers up to 60Nm of smooth, responsive torque without the bulk of traditional e-MTB motors. This lightweight electric motor system is specifically engineered for sporty trail riding, providing natural pedal-assist that amplifies your power without overwhelming the bike’s agile character. The integrated Bosch System Controller with Mini Remote offers intuitive mode changes and smart features like walk assistance.

Fox 36 Float SL Performance Suspension

Premium Fox suspension technology conquers technical terrain with confidence. The Fox 36 Float SL Performance fork (140mm travel, tapered) represents Fox’s lightest enduro-ready fork, paired with a Fox Float Performance rear shock (210x55mm, adjustable low-speed rebound, 2-position lever). This suspension package delivers plush small-bump sensitivity, mid-stroke support, and excellent bottom-out resistance for aggressive trail riding.

Shimano XT Di2 Electronic Shifting

Experience flawless gear changes with Shimano’s XT Di2 RD-M8260 electronic 12-speed drivetrain. This wireless electronic shifting system delivers instant, precise shifts regardless of conditions, load, or rider fatigue. The massive 10-51T XT cassette provides ultra-wide range for steep technical climbs and fast descents. Electronic shifting eliminates cable stretch and adjustment issues, ensuring consistent performance ride after ride.

Shimano XT 4-Piston Hydraulic Brakes

Powerful, progressive stopping comes from Shimano XT M8220 4-piston hydraulic disc brakes with 203mm front and 180mm rear rotors. These high-performance brakes deliver exceptional modulation, consistent power, and fade-free performance crucial for controlling an e-MTB on extended descents and technical trails.

The Direct Mount chain guide prevents drops on rough terrain, while the seamless integration maintains the frame’s elegant silhouette.
