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.

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.

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 increased power input with greater energy efficiency: The harder you pedal, the more the drive will support you. 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 enjoyment.

Natural riding dynamism
Finely modulated support: The powerful 32-bit processor enables sensor signals to be processed at high speeds. Performance can be controlled more precisely, offering you optimal support in all riding situations.

Thermal stability
The drive unit has highly efficient thermal stability thanks to the modern and innovative electric motor. This ensures high performance even under heavy loads.
The Bosch eBike system: A perfectly coordinated system
Bosch eBike Systems – developed for limitless freedom: Drive units, displays and batteries from Bosch eBike Systems offer technical quality of the highest order – and perform as a perfectly coordinated team. With a modular product portfolio, Bosch offers eBikers the ideal drive system for every requirement. A variety of possible combinations of drive unit, battery and display ensure an outstanding riding experience.

FAQs & more
You can update your motor at your bike dealer. Please contact your dealer regarding any costs.
You can combine the Tour+ mode with the following modes: Eco, eMTB, Turbo. You cannot combine Tour+ with the Tour mode or with the Sport mode.
Extended Boost is a new and innovative function in eMTB mode. The unique dynamism means that obstacles can be overcome with ease by applying the right amount of pressure to the pedal. The pedals rarely, if ever, jam. If the front wheel is already on the step, a slight pedal pressure is all it takes to give the decisive "kick". This takes pedal management to a whole new level.
