Unlock Bosch Gen4 Motor

Experience Full Power with Your Bosch Gen4 E-Bike

The Bosch Gen4 Performance Line CX motor set new standards for eMTBs and trekking bikes. Stronger, lighter, and smarter — yet still limited by a factory 25 km/h (15.5 mph) speed cap.

With the EBT Unlock Key, you can unleash the true performance of your Gen4 motor — 100% browser-based, without any hardware installation or risky firmware changes.

How to Recognize Bosch Gen4 BES2 Motors

  • ✔ Round charging port on your frame
  • ✔ Displays: Intuvia, Nyon, Kiox (classic), Purion
  • ✔ No LED Remote, no Kiox 300, no Flow App integration

If you see a round connector and use one of the classic displays, your Gen4 motor is ready for browser-based unlocking.


Display Behavior After Unlocking

  • After unlocking, speed and distance readings appear at approximately half of the actual values (standard behavior for Gen4 BES2 motors).
  • Performance and support levels are fully unlocked — display inaccuracies do not affect riding performance.

Why Unlock Your Bosch Gen4 Motor?

  • Remove the 25 km/h speed limit and ride with full motor support
  • No risky hardware modifications or mechanical changes
  • Simple and secure: unlock via browser with your USB cable
  • Reversible: reset to factory settings anytime

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.
