The BH51M is the world's first smart helmet for those who enjoy and frequently travel in the city. Whether you are riding a bicycle, e-bike, skateboard, inline skates, longboard, or city scooter, the BH51 feels most comfortable on the head of the modern urban athlete. The sophisticated LED system offers a true innovation in the field of bicycle helmets, featuring a day-night automatic function. The 270-degree surround lighting turns on automatically as soon as it gets dark. A real beacon of safety on dimly lit streets. When it is bright enough, the smart LEDs turn off by themselves. The weight and design of this smart helmet are also impressive. High-quality foam and a highly durable plastic shell allow for a lightweight 490 grams while ensuring high resilience. Thanks to the adjustable closure system, you can optimally fit the helmet to your head size for a comfortable fit. The Nutcase vintage look with a handmade leather visor at the front also provides literal shoulder glances. So what are you waiting for? Put on the helmet and head into the city.
