Yes, it is a Smart System
not sure

This tuning module is the right one:

All generations 1 to 4 are supported. There are no models that do not work.

Bosch Smart System: does the eBike have ABS or a valve solenoid?

No, neither ABS nor valve solenoid present
Yes, ABS or valve solenoid present

The Smart System has been available since 2022. If the year of manufacture is older, the eBike is certainly not a Smart System.

If it is not clear from the sales documents whether the eBike is a Smart System, you can easily recognize this on the display. Please read this article:

Notes on the display

The tuning module works with any display and even without one. Without a display, it is not immediately apparent whether tuning is active after switching on due to the missing display.

The Yamaha Display-A (Side Switch) does not have a decimal place. The speed can therefore not be displayed accurately.

Manufacturer other than Bosch or Yamaha / Giant

At the moment, only Bosch and Yamaha / Giant mid-motors are supported.
