Hi! Thanks for reaching out about the eBike Flow app upgrade where you noticed the watts (power) increased, but the torque (measured in Nm) did not. I want to make sure I fully understand your situation so I can help better—could you please tell me if you upgraded your Bosch Performance Line CX motor firmware through the app? Also, is the torque value simply not showing an increase, or is it actively staying at a lower setting?

Often, with the recent firmware updates for Bosch Performance Line CX Gen 5 motors, users can upgrade peak power to 750 watts and also get torque improvements up to 100 Nm. From what I know, the app allows setting the max power in increments (like 25W steps), but torque sometimes remains at default values or requires a separate firmware update on the motor itself to reflect the upgrade.

To help you achieve both upgrades (watts and torque), here’s what I suggest:

1. Check for Motor Firmware Update:
- Open the eBike Flow app and navigate to the 'Updates' section.
- Verify if there is a firmware update available specifically for your motor (not just the app). Sometimes torque improvements require motor firmware to be updated as well.

2. Adjust Performance Settings:
- In the app, look for the ‘Max Power (watts)’ tile where you can set the power level. Increasing watts here might be possible directly.
- However, for torque (Nm), the app may not offer direct adjustable values depending on motor generation; this value is tied to motor firmware capability.

3. Confirm Motor Compatibility:
- Bosch Performance Line CX Gen 5 motors, for example, can be upgraded to 750W and 100Nm as per recent updates starting July 2025, free of charge through the Flow app. If your motor is an earlier generation, torque might remain limited.
- Verify your motor model in the app’s system info and check if your motor supports the torque upgrade1 10.

4. Restart and Re-sync the eBike:
- After updating, restart your bike system and the app, then re-check the displayed torque and power values.

If after these steps you still see the watts upgraded but torque remains unchanged, it may be due to motor firmware limits or the app’s display capabilities for torque. In that case, I can help you contact Bosch support for motor-specific checks or possible deeper diagnostics.

Let me know if you’ve already tried any of these steps or what you see currently in the app, and we can troubleshoot further! Are you seeing any error messages or missing tiles for torque in the app?
