Tuning Module E-Bike PEARTUNE MSO 4.0 (Gen2/Gen3/Gen4)

The tuning module MSO 4.0 from PearTune for e-bikes and pedelecs with BOSCH Gen 2, 3 and 4 motors.

Full throttle ahead! This is exactly what the abbreviation "MSO" (Max Speed Off) of the Czech manufacturer PearTune stands for. With the MSO 4.0 tuning module, the 25 km/h speed limit is lifted and the desired top speed can be set according to personal preference. The module is installed invisibly on the engine and activated or deactivated via the control buttons on the display. It is suitable for the following displays: Nyon, Kiox, Intuvia, Cobi, Hub Cobi and Purion.

• 25 km/h limit is lifted
• Can be made invisible via lock
• Correct speed always visible

The functions of the tuning module MSO 4.0 by PearTune for BOSCH Gen 4, 3 and 2:

• With a maximum of 12 g, the module is exceptionally small and light.
• Due to the independent configuration, there is plug & play.
• Either the module is activated via the display or is always active through the "Still On" setting.
• Even if the kilometres travelled are no longer displayed correctly, they can be set. You can choose how this should be done: either at a stop or while driving.
• The module can be completely reset and installed in another e-bike, for example.
• You can determine whether the tuning is always On or Off after starting the e-bike.
• The chip can be completely deactivated by a certain +- combination. It is therefore no longer possible to see that a module has been installed. Only after a certain period of time can the tuning be switched on again by another combination.
• The speed is always displayed correctly.
• Also works with the anti-tuning software from BOSCH.

Attention: Not suitable for BOSCH Generation 4 with Smart System 2022 (BES3).
