PearTune MSO – High-quality tuning modules for e-bikes with Bosch, Yamaha, Shimano, Brose & more

What is PearTune MSO?

PearTune E-bike tuning chip

PearTune MSO (www.peartune.com) is an innovative tuning module for e-bikes with Bosch drives (Active Line, Performance Line, CX Line & Gen4), Yamaha (Powerdrive, Syncdrive), Shimano, Specialized, Brose, Giant, Bafang, Panasonic, OLI and others. It's particularly noteworthy that despite active tuning (except for Shimano), all values ​​such as speed, average, maximum speed, and distance continue to be displayed correctly on the screen.

The PearTune removes the speed limit – the term "MSO" therefore stands for "Max Speed ​​Off." Activation or deactivation is conveniently done via the buttons on the e-bike display. The high-quality workmanship and intuitive controls make PearTune one of the most popular tuning solutions on the market.

PearTune MSO 4.0 – Latest Generation

The fourth generation of PearTune MSO was introduced in 2021. In addition to the proven removal of the 25 km/h speed limit, it offers new features:

  • Individual adjustment of the maximum speed via the control buttons on the display – without a PC or smartphone.
  • Chip lock function: The tuning can be completely hidden from outsiders. The e-bike and display remain in their original state, and the tuning cannot be reactivated until it is deliberately unlocked.

PearTune MSO 4.0 is available for: Bosch Smart System (BES3), Brose,Yamaha, Giant Syncdrive, Specialized, Panasonic FIT, OLI, TQ HPR50, Bafang M-Series, Flyon (TQ) and more.
