Practical test of the O-Synce Usee head-up display
With the small O-Synce head-up display on the helmet, you can always keep an eye on parameters such as speed, heart rate or mileage while cycling, and your hands can stay on the handlebars.

Displays projected onto the windscreen in cars, or virtual reality glasses from Samsung: if experts are to be believed, head-up displays will be as common as smartphones in a few years' time. But do you need something like this when cycling? In the forest or on the mountain, where you want to escape the connected world with sweat and muscle power? According to O-Synce boss Dirk Sandrock, yes. Because with the lighter-sized box, you can always keep an eye on parameters such as speed, heart rate or mileage, and your hands can stay on the handlebars. So good, convinced.

In just a few simple steps, the Head-up display from O-Synce - the Usee - on the front of the Abus helmet. Why Abus? Because it currently only fits three race models (Abus GameChanger, Aventor, Viantor) from the German manufacturer. But an all-mountain helmet is due to follow shortly. Pairing with a heart rate chest strap and smartphone app takes just a few seconds. Incidentally, all sensors that transmit via the common ANT+ standard can be connected. Then off you go into the terrain. As the helmet and display are relatively high up, you have to consciously look upwards to see the green numbers on the display. Even swivelling the display doesn't help. The values are easy to read, whether in the blazing sun or in the dark forest. If you cut the connection, the Usee switches to sleep mode after a few seconds. You could also display the engaged gear of an electric gearstick or the charge status of an e-bike battery.

All well and good. But we find that after looking at the computer on the handlebars, it's quicker to get your eyes back on the trail.
