From May 2026, this update will allow the maximum motor torque to be increased from 100 Nm to 120 Nm on any 5th-generation Bosch CX or CX-R motor, as well as increasing the maximum pedal assistance from 400% to up to 600%.

Insalling the Performance Upgrade 2.0

A software optimisation allows the motor to pre-tension the drivetrain and prevents the motor and rear wheel from freewheeling in technical riding situations.

This reduces the free travel on the pedal and also the delay when pedalling, allowing the motor to convert your power directly into precise propulsion. With more direct traction when pedalling, your drive unit reacts immediately and gives you full control – as if the bike were glued to your foot. All that extra power remains usable, precise and easy to control on any terrain.
