SPORTY STARTING: Perfect start-up behaviour as soon as you step onto the pedals.

IMPROVED DYNAMICS: Enables effortless riding on technical uphill trails or over obstacles.

For a powerful start on steep uphill sections and on rough terrain: the eMTB mode replaces the previous ‘Sport’ mode in the Performance Line CX drive unit and switches between ‘Tour’ and ‘Turbo’ riding modes. With a maximum torque of up to 75 Nm, the motor dynamically supports the rider’s own pedal power by between 120 and 300 percent in eMTB mode, depending on the pressure applied to the pedals. Improved start-up behaviour guarantees optimal support in all terrains and on any trail. The dealer can upgrade the Performance Line CX at any time with the new eMTB mode or, if desired, load the classic Sport mode. In eMTB mode, the rider receives the required power – always precisely at the right moment. Enjoy smooth starts, cover ground more easily and arrive at your destination after an exhilarating riding sensation: that’s what the flow of the Performance Line CX is all about.
