PearTune is plugged into the e-bike system via compatible original plugs. No setup or diagnostics are required during installation. All configurations and adjustments to the settings of the respective e-bike are made automatically.
PearTune is wired between the speedometer sensor and the motor unit and between the display and the motor unit. The display power supply is used as the power supply. All data such as current, average and maximum speed, distance traveled, etc. remain on the display.
The PearTune MSO can be activated/deactivated at any time while driving by a double LONG press of the LIGHT button or by a short press of the + button and then immediately pressing the - button.
The only difference is that from the moment you install it, you determine how fast you go, not your bike. Top speed is limited only by pedaling frequency.
