Bosch eBike Systems has unveiled the Performance Upgrade 2.0, a comprehensive software enhancement for its Performance Line CX and CX-R motors, set to revolutionise the eMTB experience. This free over-the-air update, available from May 4, 2026, introduces significant performance boosts and innovative features designed to elevate riders’ capabilities on the trail.
Enhanced Torque and Support
The Performance Upgrade 2.0 elevates the maximum torque of Bosch’s Performance Line CX and CX-R motors to 120Nm, a substantial increase from the previous 100Nm. This enhancement translates to improved acceleration and climbing prowess, enabling riders to tackle steep inclines and technical sections with greater ease. Additionally, the motor support has been expanded to 600%, up from 400%, providing a more robust assistance that adapts to various riding conditions. (bikeradar.com)
Intelligent Power Delivery
Bosch’s updated software focuses on delivering power intelligently, recognising technical riding situations such as steep climbs, tight switchbacks, or awkward step-ups. The system now delivers short bursts of peak power exactly when needed, enhancing the rider’s experience without overwhelming them with constant maximum assistance. (bikeradar.com)
Customisable Extended Boost
A standout feature of the Performance Upgrade 2.0 is the adjustable Extended Boost. This function allows riders to fine-tune how long motor assistance continues after pedalling stops, aiding in clearing obstacles like rocks, roots, and ledges where a full pedal stroke isn’t possible. The overrun length can be customised per riding mode through the eBike Flow app, offering a more personalised feel on technical trails. (velomotion.net)
Drivetrain Tensioner for Enhanced Control
The introduction of the Drivetrain Tensioner software function reduces freewheel lag between pedal input and rear wheel engagement. This results in faster power transfer, improved traction, and more precise control when accelerating through demanding terrain, ensuring a more responsive and connected riding experience.

Trick Check Feature
Adding a playful element, the Trick Check feature automatically detects jumps, wheelies, manuals, and stoppies using onboard sensors. The system records duration, height, and distance, providing riders with instant feedback and tracking personal bests through the Flow app. While not essential, this feature adds an enjoyable dimension to the riding experience.

Garmin Integration
Bosch has taken a significant step toward a more open digital ecosystem by introducing a Live Data Interface that allows riders to display real-time eBike data directly on compatible third-party devices, starting with Garmin Edge cycling computers. This integration enables riders to view key metrics such as speed, cadence, total distance, rider power output, battery charge level, and remaining range on their Garmin devices, streamlining the riding experience.

12A Fast Charger
Rounding out the update is the new 12A fast charger, arriving later in 2026, capable of charging compatible batteries up to three times faster than Bosch’s current 4A unit. The 12A charger delivers around 50% charge in roughly an hour for a PowerTube 800 battery, reducing downtime and increasing time on the trail. (bikebiz.com)
