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 like actual speed, max speed, average speed, distance etc. are correctly displayed. The MSO can be activated  or  deactivated  anytime  during  the  ride  by  pressing  WALK BUTTON. The device state is indicated by a certain element on the display, so the rider always know whether the device is active or not.Thanks to original connectors the e-bike tuning can be deinstalled without any signs and original Yamaha diagnostics (highest level) did not find any signs of the device after removal.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.



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

① Remove  the  plastic  cover  under the centerdrive. Loosen the two of  the INBUS screws  (those  which  are  closer  to  the  front wheel) and tilt the motor unit towards the rear wheel. Cables and connectors are placed in the space between the motor and bike frame. 



Disconnect the 4-position connector (5- position by PW-X, 8-position by GIANT) in between the display unit and motor unit and the 3-position connector in between the tacho sensor and the motor unit.



Connect all four appropriate connectors on the MSO into the four, previously  disconnected,  mating  connectors  on  the  e-bike.  All  the conectors have a keying which prevents wrong connection, there is only one way all of them can be connected.  



Place  the  MSO  in  a  proper  position  (we  reccomend  into  the  e-bike frame, if possible) and optionaly, fasten the wiring using the electrical ties. Fold back the motor and fasten the previously removed INBUS screws. Re-attach the plastic cover and the bike is ready to go.
