PearTune MSO 3.0 for Bosch Gen2, Gen3, Gen4 & COBI

PearTune MSO 3.0 for Bosch Gen2, Gen3, Gen4 & COBI

The latest and so far best version of one of the most popular tuning modules for Bosch e-bikes ever. Compared to the previous models, the PearTune MSO 3.0 has been optimised in many ways and is now even compatible with the new Bosch 2020 Gen4 drive systems. Optionally also for smartphone hub COBI. With this tuning tool, you can completely remove the 25 km/h speed limit and finally experience the full power of your Bosch drive system. All this with correct speed indication on the display! Of course, the PearTune MSO 3.0 has all the advantages of the previous modules:

-The speed limit is completely removed ("MSO" stands for "Max Speed Off").

-Correct values on the display (real display of speed and other values such as distance, average and maximum speed etc.).

-Tuning can be switched on or off at any time using the WALK button. When tuning is switched on, the display briefly shows 9.9 km/h - this confirms that tuning has been activated. When tuning is switched off, the display briefly shows 2.5 km/h as confirmation. Tip: Alternatively, the tuning can also be activated with the key combination + - + -. Note: With the variant for COBI, a long press of any button is sufficient.

-For Bosch e-bikes without the WALK button, there is also the optional "Still On" variant, in which the tuning is always active after switching on.

-Easy installation: The PearTune module simply needs to be connected between the motor and the display and between the motor and the magnetic speed sensor.

-No separate battery is needed for the module (power is supplied via the display connector).

PearTune MSO 3.0 for Bosch - improvements compared to previous models:

-New innovative processor for even more power

-New, improved software

-Original connectors for easier installation ("Plug & Play")

-New hardware design

-Extremely small and light: The module is twice as small as before, making it even easier to install. The weight is just 12 g.

-Now also compatible with the new Bosch 2020 motors & displays

-Backwards compatible with Bosch e-bike motors from 2014 to 2020 (Bosch Gen2, Gen3 and Gen4)

PearTune MSO 3.0 for Bosch - Compatibility

-The smartphone hub COBI variant is only compatible with Bosch Gen4.

Not compatible with Bosch Smart System 2022 (BES3)!

The PearTune MSO 3.0 for Bosch is available in three versions:

-In the Normal version ("Display"), the tuning can be switched on and off via the WALK button (alternatively press + - + -).

-With the "Still On" version, the tuning is always active as soon as you switch on the e-bike. This version is intended for Bosch e-bikes without the WALK button.

-Bosch smartphone hub COBI version: Activation takes place by pressing any button for 5 seconds.

Tip: Bosch Smart System e-bikes (BES3) can be easily recognised by the charging cable plug, among other things.

SQUARE plug = Bosch Smart System BES3 (Gen4) + Bosch Gen5:

ROUND plug = Bosch Gen2, Gen3 & Gen4:

If your Bosch e-bike charging cable has a round plug (as shown above), you have selected the correct tuning module (provided the bike does not have ABS). If your Bosch e-bike does not have either connector, you either do NOT have a Bosch e-bike or an e-bike with the old Gen1 drive (Classic Line).
