Frequently Asked Questions
Is my Gen4 motor supported?
Yes, if your Bosch Gen4 motor uses a round charging port and classic displays like Intuvia, Nyon, Purion, or Kiox.
No, if your system uses LED Remote, Kiox 300, Intuvia 100, or the Flow App (then it’s BES3 – not supported).
Will my speedometer show the correct values?
After unlocking, the display will show about half the real speed — this is normal and does not impact motor performance.
Can I reset to the original 25 km/h limit?
Yes. Resetting is possible anytime via the browser using your unlock key credentials.
Is unlocking complicated?
No. It’s easy: connect your Bosch display via USB, open your browser, enter your license key — done in minutes.
