Bosch has unveiled the Performance Upgrade 2.0, a significant enhancement for its Performance Line CX and CX-R e-bike motors, set to be available from May 4, 2026. This free over-the-air update offers riders increased torque, improved support levels, and new features designed to enhance the e-mountain biking experience.
Enhanced Torque and Support
The Performance Upgrade 2.0 elevates the maximum torque of Bosch’s Performance Line CX and CX-R motors to 120 Nm, up from the previous 100 Nm for the CX and 85 Nm for the CX-R. This boost provides riders with more power during challenging climbs and technical sections. Additionally, the maximum support level increases to 600%, up from 400% for the CX and 340% for the CX-R, delivering greater assistance during demanding rides. (bikemag.com)
Intelligent Power Delivery
Bosch’s intelligent software dynamically adjusts power output based on riding conditions. The system automatically delivers full power during steep climbs, technical root sections, and tight curve exits, providing a seamless riding experience. This approach ensures that riders receive the necessary support when needed, without compromising battery life or drivetrain longevity. (electrek.co)
Adjustable Extended Boost
The Performance Upgrade 2.0 introduces an adjustable Extended Boost feature, allowing riders to customize the duration of the boost to suit their riding style and terrain. This feature is particularly beneficial for overcoming obstacles like roots or rocks without completing a full pedal stroke. The boost duration can be fine-tuned via the eBike Flow app, offering a personalized riding experience. (velomotion.net)
Drivetrain Tensioner
To enhance drivetrain responsiveness, Bosch has incorporated a new drivetrain tensioner that pre-tensions the drivetrain when it detects lag between the motor and the rear wheel. This feature, available in eMTB or Race mode, minimizes drivetrain slack and provides instant acceleration, improving performance during aggressive riding. (bikezona.com)
Trick Check Feature
For riders interested in tracking their performance, the Trick Check feature records the duration, height, distance, and angle of jumps, wheelies, manuals, or stoppies. The system displays the last trick on the display for eight seconds and allows riders to review their trick data at the end of the ride, fostering skill development and providing a fun way to monitor progress.

Its compact and lightweight design makes it convenient for riders to carry and charge their bikes during tours or at work. (bikezona.com)
