PearTune MSO 4.0 tuning e-bike Specialized 3.1 Gen4

PearTune MSO 4.0 for SPECIALIZED 3.1 Gen4 is an e-bike tuning chip used to remove the 25km/h ( 101, 111 Nm) limit or speed limit on the Specialized 3.1 Gen4 mid-drive e-bike in any combination with all available displays as well as the Speacialized app.

The PearTune plugs into the e-bike system using compatible original connectors. No setup or diagnostics are required during installation. All configuration and adaptation to the settings of the specific e-bike is provided automatically.
PearTune is wired between the speedometer sensor and the motor unit and between the display and the motor unit. The power supply is used as the power supply for the display. All data such as current, average, maximum speed, distance travelled, etc. remain true on the display.

The only difference is that from the moment of installation you, not your bike, determine how fast you go. The maximum speed is limited only by the frequency of pedaling.

USE:

The PearTune MSO function can be switched on or off at any time during a ride by briefly pressing the walk button. The function of this button remains unchanged by a long press. Accelerator activity is shown on the display by flashing the selected assistance level indicator and displaying the value 9.9 km/h (2.5km/h) immediately after switching the device on (off).
