BikeConnect: Control your phone using Di2 buttons

Updated July 14, 2026by BetterShifting Terry

Bike Connect is an app that lets you control your phone using your Di2 D-fly buttons - it works with both 11-speed and 12-speed Di2.

Bike Connect is available on iPhone, Mac and iPad. An Android version is in the works.
