PearTune MSO 3.0 for Bosch Gen4 Smart System 2022

PearTune MSO 3.0 for Bosch Gen4 Smart System 2022

Also compatible with Bosch Gen5!

The PearTune MSO 3.0 removes the 25 km/h speed limit of Bosch Smart System e-bike motors. This gives you the option to finally use the full potential of these powerful drives. "MSO" therefore also stands for "Max Speed Off"!

This is the "NORMAL" version of the PearTune MSO 3.0 module, where you can conveniently switch the tuning on and off using the + and - buttons on your e-bike.

A PC or smartphone is not required to operate the PearTune module.

Tip: If your Bosch e-bike is not equipped with the required control buttons, you can also order the PearTune 3.0 in a special Still On version - in this case, the tuning module is always active as soon as you switch on your e-bike.

Correct speed remains readable

If the Tuning Chip has been activated, your e-bike display will show the correct speed up to 22.9 km/h. At higher values, the correct speed remains readable, albeit via the second digit and the decimal place of the speed display. This means that a displayed speed of 23.3 km/h would actually correspond to 33 km/h, a display of 24.0 km/h would correspond to 40 km/h, etc.

All other values are shown correctly on the e-bike display.

Installation

The PearTune MSO 3.0 is a module that must be installed between the engine and the speed sensor and between the engine and the speedometer (display). To gain access to the necessary plug connections, the plastic cover of the motor must be removed briefly during installation.

Important: If you want to use the PearTune module on a brand new e-bike, you should first ride the bike for at least 1 km before installing the tuning.

-Tuning can be activated / deactivated: You can activate and deactivate the tuning at will using the + & - buttons on your e-bike (++-- or +-+- or --++ or -+-+). The display shows you whether the tuning has been activated or deactivated (short display of approx. 19.0 km/h = tuning active / short display of approx. 12 km/h = tuning deactivated).

-Also compatible with Bosch Smart System Gen5 (from 2024 onwards), sometimes also referred to as ‘Bosch CX Gen5’.

-Compatible with all displays & control units: Kiox 300 / Kiox 500 / Kiox BUI330 / Intuvia 100 / System Controller / LED Remote / Mini Remote / Purion 200. Even compatile with Purion 400 (Bosch Gen5).

Attention: Please do not carry out any Bosch updates after installing and using this tuning module! Compatibility may then no longer be guaranteed!

Important: Not compatible with e-bikes with rim magnet (magnet on the valve)! These sensors are installed deep in the motor and cannot be optimised with this module (rim magnets can be recognised by the large magnet on the rear wheel valve).

Not compatible with Bosch e-bikes with ABS system!

For Bosch e-bikes without the + and - buttons needed to activate/deactivate the tuning, the module is also available in a Still On version, where the tuning is always active when the bike is switched on.

Our tip: The PearTune MSO 3.0 tuning module is limited in its range of functions to the absolute essentials - the removal of the 25 km/h speed limit. However, this module is also available in an MSO 4.0 version (“PearTune MSO 4.0 V2 for Bosch Gen4 Smart System“), which has a much wider range of functions. For example, the maximum supported speed can be set to an individual value; or you can set an individual activation code. Particularly original is the chip lock function, with which the tuning can be made "invisible" to others for a short time.

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 square plug (as shown above), you have selected the correct tuning module (provided the bike does not have ABS or a rim magnet). 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).
