The Bosch Performance Upgrade 2.0 is a free software update that significantly increases the output of compatible Bosch CX and CX-R drive systems. Torque climbs to 120Nm, and maximum motor support reaches 600%, with full power available for longer on the climbs that need it most.
Every bike on this page is compatible with the upgrade. Whether you are on a 2025 or 2026 model, you can install it yourself through the eBike Flow app once your bike is registered. Your nearest Cube dealer can check your drive components beforehand and help with anything along the way.
