Bosch Performance Line CX: More power, more control.
The most used motor in e-MTBs gets an update, and it’s not just a minor restyling: the Bosch Performance Line CX steps up to a new level.
Thanks to the new update, the motor is now more powerful and more manageable through new customization settings, a new mapping, and increased maximum power.
What’s new for the CX?
The torque of the Performance Line CX increases from 85 to a full 100Nm, resulting in 400% pedal assist and a power peak of 750W compared to the previous 600W.
But brute force isn’t the only update to Bosch’s drive unit—new functions are now available to customize assistance behavior and adjust levels directly from your smartphone. Most notably, the new eMTB+ mode is here.
What is it about?
The new eMTB+ mapping is the bridge between the eMTB mode—popular for its smooth and controllable power delivery—and the Race mode, which unleashed all the torque and power of the Performance Line CX for high-speed segments or extreme climbs.
eMTB+ combines both, always providing all the power needed to overcome any obstacle, while ensuring the bike doesn't become uncontrollable or unpredictable. It maintains great control and increases rider confidence even when unleashing all the motor’s power. The drive unit can "read" the situation and shift from full power to a subtle traction control without needing any mapping changes.
New Performance Line CX-R
Bosch didn’t just update—new units have also been created!
The big news is the brand-new Performance Line CX-R motor. If eMTB+ mode bridges two mappings, the Performance Line CX-R motor is the union of two drive units designe
