【Add Protection to Your Cycling】The SH55M Smart Safety Helmet developed by Smart4U comes with six bright LED rear lights, a turn signal and three display modes. Allows other drivers on busy roads to notice your presence and know which direction you are turning, day or night.

【Enjoying the Riding】This bike helmet is Bluetooth enabled and can be paired with your phone. The helmet has two speakers and a noise-cancelling microphone, allowing you to enjoy music while riding in the wild, in the mountains or on urban roads, adjust the volume, answer calls and take photos via a remote control or mobile app.

【Every Detail Makes You Feel Comfortable to Wear】The SH55M bicycle helmet is made of high-quality materials, using the inside and outside integrated molding process, giving the helmet a sturdy shell, and weighing only 310g. It absorbs the impact of the impact, but it doesn’t make you feel heavy. Built-in removable quick drying lining makes you feel soft and comfortable when wearing.

【Best Safety Defense】When you are accidentally hit while riding in the wilderness or mountains, if you do not move for 30 seconds, the unique patented algorithm will automatically trigger an SOS alert, sending your GPS location to your phone’s emergency contact for a quick rescue.

【Customer First】SH55M intelligent bicycle helmet is one of the products independently developed by SMART4U. It adopts active and passive defense design to protect the safety of every rider on the road. If you have any questions after purchase, please feel free to contact US.
