More torque

Powerful: the torque of up to 85 Nm has a noticeable effect on riding behaviour. This accelerates faster, particularly at low cadences, and makes uphill starts much easier. You therefore have more power available in difficult gears.

Natural riding dynamism

Fine-tuned support: the powerful 32-bit processor enables sensor signals to be processed at high speeds and for precise power control. The power can be controlled more precisely, offering you optimal support in all riding situations.

Perfect control

Ready for every challenge: The advanced eMTB mode ensures even better control on the trail, without having to switch riding modes. The motor responds much more sensitively to the rider's effort, especially in low gears, enabling an extremely sensitive start.

Sporting efficiency

Choosing a sporty riding style can take you further with Tour+ mode. The riding mode rewards your slightly higher effort with energy efficiency: if you pedal harder, the drive offers you correspondingly greater support. If, on the other hand, the going is fairly easy, you'll receive less assistance. This means that the battery is discharged more slowly. This will extend your ride, as well as your riding fun.

Extended Boost

Impressive performance on the trail: Extended Boost is the unrivalled function for negotiating exposed roots, steps, and stones with ease, even uphill. This function enables you to manoeuvre with greater agility and ease on even the most technically demanding trails.

Thermal stability

For the greatest challenges: the drive unit is highly efficient and thermally extremely stable thanks to the modern electric motor with modern bar winding. This ensures high performance even under high loads.
