Compatibility

Important note on BDU logic for Bosch Smart System:
When choosing the correct solution for a Bosch Smart System e-bike, the general label “CX”, “Performance Line” or “Smart System” is often not specific enough. In many cases, the exact BDU code of the drive unit is the more relevant identifier. The BDU is Bosch’s internal designation for the motor family and helps distinguish between technical variants and special configurations.

In practice, shortened family labels such as BDU31, BDU33, BDU37 or BDU38 are often used. These short labels usually refer to entire BDU families rather than one exact variant. That is why a designation like BDU37 may cover several specific sub-versions.

Typical Bosch Smart System BDU families include:

  • BDU31
  • BDU33
  • BDU37
  • BDU38
  • BDU3142
  • BDU3143
  • BDU3144
  • BDU3145
  • BDU3780
  • BDU3781

Known Bosch Smart System drive units / BDUs:

  • Performance Line SX – BDU314Y
  • Active Line – BDU332Y
  • Active Line Plus – BDU334Y
  • Performance Line – BDU336Y / BDU346Y
  • Performance Line PX – BDU347Y
  • Performance Line CX – BDU374Y / BDU384Y
  • Cargo Line – BDU374Y / BDU384Y
  • Performance Line CX Race Limited Edition – BDU376Y
  • Performance Line CX-R – BDU386Y

Why this matters in practice:
Shortened labels such as BDU31 or BDU37 can be useful for first orientation, but they are often not precise enough for a full compatibility assessment. The final evaluation always depends on the specific combination of BDU, rim magnet, ABS, e-Shift and the overall Smart System configuration. If you are unsure, check the exact BDU code in the eBike Flow app before ordering.

Important Information & Tips

  • Please enter the licence key with hyphens and without spaces.
  • Make sure you use a fully functional USB data cable, not a charging-only cable.
  • The USB port may be located on the display, the remote or the controller in the top tube, depending on the bike.
  • The activation process may take several minutes.
  • After activation, the riding profiles should be configured correctly in the eBike Flow app.
  • For maximum assistance performance, factors such as riding mode, support setting, gearing, drivetrain adjustment and tyre pressure are relevant.
  • You can switch back to the original 25 km/h limit at any time and re-activate the unlock later if required.
  • The optional 45 km/h setting can be selected repeatedly, but it is not available for bikes with ABS.
  • Once the licence code has been used, it is excluded from refund.
  • If minor bugs occur, they are documented and considered in future updates.
