PearTuneAll PearTune products

PearTuns MSO (“max speed off”) is a tuning product for e.g. electric bicycles with Bosch, Yamaha, Giant, Shimano or Brose drive systems ( It will take away the speed limitation and de-restrict your electric bike engine. If you use this tuning tool, all relevant data like current speed, distance, average- and max-speed will be shown correctly on your display – even if the tuning is activated (however, there can be some deviations with some variants). The PearTune MSO tuning tool can be easily controlled via the operating buttons of your electric bike display.
