PearTune MSO (www.peartune.com) is an innovative tuning module for e-bikes, including models with Yamaha (Powerdrive and Syncdrive), Shimano, Specialized, Giant, Brose or Bosch drives (Active Line (Plus), Performance Line, CX Line & Gen4). The special feature of the PearTune is that the e-bike display continues to correctly show all data such as current speed, average and maximum speed as well as distance (except Shimano), even when tuning is active. In addition, the PearTune MSO completely removes the 25 km/h speed limit - this means that with this tuning tool you can really get the full power out of your e-bike motor! Accordingly, "MSO" stands for nothing other than "Max Speed Off". The tuning can be easily switched on or off using the buttons on the display. The PearTune MSO is a very high-quality product.
Peartune MSO 4.0 - The latest generation
In autumn 2021, the fourth generation of these popular tuning modules came onto the market: PearTune MSO 4.0. These revised versions of the modules can do everything that the previous models could do, with the core function still being the removal of the 25 km/h speed limit (with correct speed indication in the display). However, the range of functions has been considerably expanded. The most important new features are:
- For the first time, there is the option to set the level of the maximum speed of the e-bikes to an individual value. This is done using the control buttons on the display; a PC or smartphone are still not necessary. - Chip lock function: With this original feature, the tuning can be made "invisible" to outsiders. Once the chip lock has been activated using the bike's control buttons, the e-bike and display function as they did originally. The tuning can also no longer be activated, so that outsiders cannot see that a tuning module has been installed. The chip lock can only be removed after a certain time, after which the tuning works again.
PearTune MSO 4.0 modules are currently available for: Bosch, Flyon, Brose, Yamaha, OLI, Giant, Specialized...
