Reason for development:

To have better sight and to avoid turning around on the bicycle to know what is going on behind you.


Idea in short: A rear camera records the movements around the bicycle and the images are shown on a display on the steer. The cyclist knows what is going on behind the bicycle without having to make extra manoeuvres. This allows the cyclist to keep focus on the road and to avoid instability.
