From May 4th, Bosch makes available the Power Upgrade 2.0 update for the fifth generation Performance Line CX and CX-R engines. The software increases the maximum torque up to 120 Nm and the assist factor up to 600% in specific situations. Usuários with compatible bikes can download the new feature directly via the Flow eBike app.
The measure responds to the demand for more power on technical sections, especially on e-MTBs and cargo bikes. The upgrade maintains the peak power rating at 750 watts, but intelligently improves power delivery. Extended Boost now allows individual duration adjustments and can be disabled. The system also includes a transmission tensioner that activates with a slight movement of the pedal.
Atualização Power Upgrade 2.0 focuses on on-demand performance
The main advance is in intelligent power management. The engine delivers the extra torque contextually, recognizing steep climbs, obstacles or corner exits. Isso avoids unnecessary battery consumption on flat stretches. The 600% support is valid up to 15 km/h, useful for sprinting with heavy loads.
Ciclistas adjust settings in the Flow eBike app before the first ride after installation. A warning message appears on the screen. Depois then the system is ready. Bosch highlights that the upgrade is optional and respects the legal limits of 25 km/h for assistance.

Tensionador transmission and Garmin integration extend control
The new tensioner activates with a slight backward movement of the pedal. Ele pre-tensions the chain and reduces wear during sprints or sudden accelerations. The feature improves the engine’s overall sensitivity and reduces noise or efficiency losses.
Outra new feature allows you to pair Garmin devices directly with the Bosch system. The cyclist views power, cadence and assistance data on the watch or on-board computer without extra intermediaries. Essa connection facilitates training and performance analysis.
The 12A fast charger with GaN technology is more compact than the current version. Ele promises up to three times faster recharges in some scenarios, although it is expected in late 2026 or early 2027. The software update is not dependent on this hardware.
