LIVALL MT1 Bike Helmet is not only a helmet. LIVALL Smart Helmet = Turn Signal SOS Alert Phone Calls Music Player Walkie-Talkie.

All for Safety: Safety is a Top Priority. Hereby we present you LIVALL Smart Helmet, a multi-functional helmet that provides you with more than safety.

Get Help in Time: Added a 3-axis G-sensor to the helmet to make sure you can get help in time in case you fall. Once the G-sensor senses unusual gravity acceleration, the emergency signals on the helmet will be turned on and an SOS alert will be sent to your emergency contacts automatically. Very useful when you're cycling alone.
