Central motor BOSCH Performance Line CX Smart system


BOSCH Performance Line CX Smart System. A powerful and dynamic motor for intuitive handling and a unique driving experience. Thanks to its multi-sensor concept and innovative Bosch motor management, the Performance Line CX Smart System sets new technical standards - responding flexibly and responsively to develop its full potential on technically demanding tracks.

One powerful feature is the eMTB mode, which uses exactly as much power as needed and allows you to focus all your attention on driving. In the eBike Flow app, you can adjust the support, dynamics, drive torque and top speed of your eBike in Eco, Tour, Sport and Turbo riding modes to suit your individual needs.




Strong support 

With a weight of 2.9 kg and a maximum torque of 85 Nm, it delivers greater driving pleasure on demanding trails despite its extremely compact dimensions. The eMountain mountain bike motor is compact, lightweight and extremely powerful, combining high-quality materials, an extremely powerful drive and high-end sensors.

Real power 

The maximum torque of 85 Nm has a noticeable effect on mountain biking performance. The powerful motor enables fast acceleration around sharp corners and obstacles at low cadence and makes it easy to take off up the steepest hills. For fast sprints, the engine will also support you at high cadence.

eMTB mode

The eMTB mode is specially designed for sports use and offers optimal control and intuitive handling, as there is no need to switch between different riding modes. Thanks to this clever eMTB mode feature, technical sections can be tackled with confidence and obstacles such as roots and thick branches can be overcome with targeted pedal pressure using the Extended Boost function. The Performance Line CX Smart System powertrain thus ensures an even greater riding pleasure and flow experience.

Tour+ mode

Sporty riding on a trekking e-bike or eMTB: Tour+ mode allows the rider to concentrate solely on enjoying the ride. It removes the need to manually switch between riding modes and saves energy by increasing the rider's power output. This ensures a natural riding experience in every situation, even on longer rides.

Speed sensor 

In addition to the wired solution, the intelligent system is equipped with an internal speed sensor located in the drive unit. The wired sensor is eliminated and the magnet on the spoke is now attached directly to the wheel, resulting in a cleaner look for the eBike.
