The shifter(s) on my Wattbike AtomX are vibratingUpdated 20 days ago

The AtomX has a in-built haptic feedback for an improved immersive riding experience, so when pressing the shifter button you will feel a vibration rumble.

When pressing the action button, push the button in the middle of the red part of the shifter. 

If the shifters continually vibrate, adjust the shifter hoods slightly to ensure they are fitted correctly and have not moved.
