Detailed product description:

PearTune is connected to the e-bike system with compatible and original connectors. The  MSO  does  not  need  to  be  configured  manually.  The  entire configuration and adaptation to the paticular e-bike is done automatically. The  MSO  is  connected  in  between  the  magnetic  speed  sensor  and  the motor  unit,  and  in  between  the  display and  the  motor  unit.  MSO  is powered from the display connector. All readings about speed like actual speed, max speed, average speed are correctly displayed. Only the distance could be read a little bit less than real is.

The MSO can be activated  or  deactivated  anytime  during  the  ride  by  pressing of  LIGHT BUTTON or "+" and  "-" buttons. The device state is indicated by the speed gauge which will show "9.9"/"2.5" for a short while after activation/deactivation the PearTune, so the rider can always know whether the device is active or not.

Thanks to original connectors the e-bike tuning can be deinstalled without any signs.

The speed limit is REMOVED completely without any side effects. Not just shifted to 50km/h.

The only difference is that from the moment of installation you, not your bike, determine how fast you go. The maximum speed is limited only by the pedaling frequency.

Avalaible also in "STILL ON" version - make a note during your order and we will configurated it for you to Still ON version - the PearTune is then ON/OFF automatically when your bike is ON/OFF. So, no buttons for activation are needed.

Compatible original connectors, extremely miniature waterproof enclosure. Can be deinstalled without any signs.

  • Unlike similar sets, this device shows no display flickering or other unwanted effects. Everything else, but the speed limit removal, stays the same.
  • The only difference is that you can go the speed you want with your bike. 
  • 60km/h with assist? Just plug & enjoy!



The MSO can be activated or deactivated anytime during the ride by once short-press  of  the  light  button  or +-+- buttons.  Original  function  of  this  button remains unchanged with a long-press and the walk assist function can be used like before.
