Hi all I have a cube reaction with the Bosch 2nd gen centre drive system, I recently rode the bike without the computer screen attached and no assistance for a couple of miles a few days later I clip the screen back on and it is not connecting to the motor. The battery is fine because it is lighting up but just not connecting or showing speedo!
Could this be anything to do with the few miles I did without the computer. Does it need resetting or something?
Any help would be much appreciated.
Thanks in advance
Have you tried taking the display unit off and putting it back on again? May have just been a bad connection. If there is an error then it usually displays a code at the bottom of the display.
