Bike Connect: Ride in Control

Bike Connect turns your Shimano Di2 bike's hood buttons into powerful controls for your iPhone, iPad, and Apple Watch so you can stay focused on the ride, not your screen. Control music, lights, gear display, and more right from your handlebars. On Apple Watch, get a glanceable gear readout and a quick bell. No phone required.

Compatible with Bluetooth-enabled Shimano Di2 groupsets, including 105, Ultegra, Dura-Ace, GRX, and select MTB Di2 groupsets with programmable hood/top buttons.

What you can do from your handlebars with just a tap (or two)

- Full music control: Play, pause, and skip with Apple Music, Spotify, and more

- Volume at your fingertips: Turn volume up or down, or mute instantly

- Use your flashlight as a headlight: Toggle the flashlight on/off or perform a quick flash

- Ring a virtual bell: Play a bell sound through your speaker, even when the screen is locked

2. Assign each hood button (D-FLY channel) to your preferred action

Why Bike Connect?

Traditional cycling head units require extra mounts and menus. With Bike Connect, your existing device stays in your pocket or on the bars while your thumbs do the work that matters: skipping to a high-energy track, muting for traffic, flashing your light at a junction, or ringing a virtual bell. Less distraction, more ride.
