USEE - the first head-up display for bicycle helmets.

On the move with heart rate belt and power meter during training?
Convinced e-bike rider and purist on the Specialized Turbo Levo?
All-weather rider who also travels in the darker seasons and wants to explore new areas?

NOW NEW: Helmet options for different Specialized Helmets

The USEE® is a head-up display for cyclists and enables intelligent monitoring of all relevant performance parameters as well as safe navigation in all conditions. In addition to the existing bike computer or even as a complete replacement!

Eyes-on-the-Road-Benefit:  With the USEE® the view remains on the road and the hands on the handlebars.

With a weight of only 20 grams, the USEE® cannot be felt on the helmet. The LCD display allows excellent legibility of the information displayed in any weather situation - with or without glasses. It automatically adapts to the lighting conditions of the environment thanks to the UV collector. The extremely high load capacity and the 100% waterproof housing, combined with a battery life of up to 400 hours, make the USEE® a perfect extension for all cycling enthusiasts who do not want to lose sight of performance or safety.

Display and operation

The display of the USEE® consists of two areas and with the simple One-Button-Desgin you can easily switch through the different display modes. The position of the display can be flexibly adjusted using the adjustable holder.



Four integrated LEDs provide permanent illumination of the display in the dark. So even at night and in fog, all important data remain in view.

Modes of operation

The USEE® can be operated in two different modes.

Stand alone mode:

The data of all connected ANT+ sensors are displayed directly.

For example, speed, cadence, heart rate, power, electronic shifting, e-bike drives with the LEV profile.

Smartphone mode:


The USEE® forms a bridge from ANT+ sensors to any smartphone or sports watch that supports Bluetooth® Low Energy. In connection with our everyday companion, the smartphone, the functional range of the USEE® expands and it becomes a second display. It now displays not only the data from the ANT+ sensors, but also data from the smartphone. The smartphone's display remains switched off, the device is safely stored in your pocket and the battery life is long.

Information such as altitude (GPS), speed (GPS), time or navigation instructions are taken directly from the smartphone and displayed in the USEE®. For this purpose, the apps o-synce mobile* or Naviki** can be used, for example, and the data of all sensors of a ride can be recorded in order to evaluate them later or make them available for well-known training platforms.

Special features

Training computer for ambitious cyclists

The USEE® displays heart rate and current power side by side when connected to a heart rate monitor and a power meter.


Display for E-Bikes

E-bikes with the ANT+ LEV profile (e.g. Specialized Turbo Levo & Kenevo) pass information such as battery status, support level, performance, cadence and speed directly to the USEE®.


*o-synce mobile can be downloaded free of charge from Google Play Store and the App Store.

**The Naviki App can be downloaded for free from the Google Play Store and the App Store. The turn instructions from Naviki cost 3,79€ for Android and 3,99€ for IOS. Offline maps are available from 4,79€.
