A New Era in Electric Mountain Biking
The Performance Line CX offers a unique eMTB experience: compact, lightweight, and more powerful, combining premium materials, extremely strong drive, and top-class sensors. It takes eMTB riding to an entirely new level. Starting from the 2021 model year, it provides up to 85 Nm torque, new motor control functions, and an improved eMTB mode—all available as a software update. For a thrilling riding experience: more natural, more intuitive, and more powerful—setting the benchmark in its class.
Benchmark Experience: From the 2021 model year, the Performance Line CX delivers even more fun on the trail – with improved software and a maximum torque of 85 Nm. The increased torque provides higher performance and more support, especially at low cadences. In EMTB and Turbo modes, this results in significantly faster acceleration and makes starting uphill much easier. Thanks to the wider cadence range, unpredictable situations can be handled even more effectively—for example, late gear shifts or accelerating out of tight corners.

Impressive trail performance: Extended Boost is a unique feature for effortlessly conquering roots, steps, and rocks—even uphill. This function allows for greater agility and easier maneuvering on the most technical trails.
Perfect Control
Ready for any challenge: The advanced eMTB mode provides even better control on trails without needing to switch modes. The motor reacts much more sensitively to the rider's effort, especially at low speeds, allowing for extremely smooth starts.
Maximum Agility
Exceptional responsiveness: Thanks to the multi-sensor concept, which performs over 1000 measurements per second, the drive unit offers an extremely responsive reaction.
Natural Dynamics
Perfectly controlled support: The powerful 32-bit processor enables high-speed processing of sensor signals. Performance is precisely controlled, providing optimal support in every situation.
Thermal Stability
For extreme loads: The drive unit is highly efficient and features a fully maintenance-free 16-pin BLDC electric motor with the latest rod winding technology, offering high thermal stability. This ensures consistent performance even under continuous load.
Powerful Assistance
One pedal stroke, and the power kicks in. The precisely delivered support of the Performance Line CX provides an even more enjoyable experience in every situation. No mode switching, no overheating—just optimized control: With ample power supply from Bosch PowerPacks or PowerTubes and perfect feedback from the onboard computer, you can focus solely on the thrill of riding.
Support Even While Pushing the Bike
Hillsides or forest terrain full of protruding roots: the specially developed, optimized, smooth, and powerful support function for pushing the bike lets you overcome almost any obstacle without delay. The walk-assist function automatically adjusts speed and starting behavior according to the slope.
eMTB Mode Function
In eMTB mode, you can switch between Tour and Turbo levels. Depending on the pressure on the pedal, the progressive assistance system automatically adapts to the rider's cycling style, providing dynamic assistance between 140% and 340%. Even without changing modes, the motor always delivers the ideal level of support—even during slow pedaling. Steep slopes are no longer a challenge, off-road riding becomes easier, and you benefit from significantly improved traction. The system provides a natural pedaling feel and optimal performance.
