The perfect helmet for city dwellers, commuters and old town cruisers, for asphalt lovers, urban stylers and cool types. Light on for the BH51! The BH51 is the world's first smart helmet for anyone who likes to travel around the city. Whether you're on the move by bike, e-bike, skateboard, inline skate, longboard or city scooter - the BH51 feels best on the head of the modern city sportsman. The ingenious LED system offers an absolute innovation in the field of bicycle helmets, a "day-night automatic". The 270° all-round lighting switches on automatically as soon as it gets dark. A real ray of hope when it comes to safety on dark roads. If it's bright enough, the smart LEDs go out again automatically. The weight and construction of this smart helmet are also impressive. Qualitative foam material and the high-strength plastic bowl make light 490 gram and high resistance possible. Thanks to the adjustable fastening system, you can adjust the helmet optimally to your head circumference so that it sits comfortably. The Nutcase-Vintage look with a handmade leather shield on the front provides for literal shoulder glances. So what are you waiting for: helmet up and down into the city centre!
