size L, 57-61 cm 370g ABS-plastic ratchet closure white rear light, SOS function, brake light Product description The LIVALL C20 – the safe companion for everyday use. The LIVALL C20 is the entry into the world of multifunctional helmets and a lightweight bicycle helmet with rear & brake light as well as fall detection and SOS emergency call. Safety and riding fun are inseparable on a bicycle. For many, it is the means of transport of our time and has become almost indispensable for everyday life in the city. With the LIVALL C20, there is now a companion that looks out for its owners. The brake & tail light positioned high on the head increases the visibility of the rider. Especially in heavy traffic in the city, you will be noticed much earlier than with a conventional rear light. For those who sometimes ride their bike alone, the LIVALL C20 has a very special feature in this price range. Motion sensors continuously monitor the position of the helmet and detect when strong forces are acting on the helmet, such as from a fall. The helmet reports this to the LIVALL app, which in turn informs an emergency contact via SMS. Like a little guardian angel that lives in the LIVALL C20. To ensure that it is always active when its owner is, the LIVALL C20 switches on automatically when the helmet is moved and deactivates after 5/10/20 or 30 minutes of inactivity.
