Stem or bar-mounted display for your Smartphone cycling apps


If you’re currently using your smartphone for logging your rides and would like to be able to see at-a-glance your current speed or trip distance so far etc, the 3T Eye might be what you’re after.

3T Eye is a robust, handlebar-mounted digital display that supports navigation and training.

It monitors the outputs both of training aids communicating via ANT+, and smartphones communicating via Bluetooth.

Paired with a suitable input device, it’s capable of displaying key data such as speed, cadence, heart-rate, altitude, and power, in real time.

In Bike Mode, 3T Eye automatically pairs with any ANT+ sensor, such as a heart-rate monitor or power meter, and displays the data on its screen.

In Smart Bridge Mode, it captures data from an ANT+ sensor and transmits it via Bluetooth 4.0 to a compatible sports app running on a smartphone, as well as displaying the data.

In Smartphone Mode, it exchanges data automatically with the 3T Cycling app (available for Apple IoS™ and Android™) running on a smartphone, enabling real-time data display, monitoring, and recording. Most important for many riders is speed, which is calculated using the phone’s GPS.

3T Eye’s miniature, line-of-sight display means there’s no need to take the phone out of your jersey pocket to check your numbers. Key training data is always visible, while you’re costly and fragile smartphone is kept securely out of harm’s way.
