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.

INSTALLATION PROCEDURE:
installation procedure
MSO-BF-CAN: ① Unscrew the screws and remove the plastic cover from the motor on the other side of the transducer. All the necessary cables and connectors are located under this cover in the space between the motor and the bike frame.
② Disconnect the 8-pin connector between the display and the motor and the 4-pin connector between the speed sensor and the motor.
③ Plug the two corresponding connectors of the MSO into the motor unit instead of the original display and speed sensor connectors.
Then connect the original display connector and the original speed sensor connector previously disconnected from the motor to the remaining MSO connectors.
All connectors are keyed to prevent bad connection; there is only one way to connect them all.
④ Place the MSO in the right place (preferably in the frame of the electric bike, ideally with the housing of the chip facing up = moisture protection) and optionally attach the wiring. Reattach the plastic cover, tighten the screws previously removed and the bike is ready to ride again.
