Bypoint stands for bicycle safety. That is why we have developed our S-ERT helmet, an innovative bicycle helmet that not only makes you cycle safely but also makes you extra visible. Discover ultimate protection and style with our new helmet! Designed with the latest technologies, this helmet not only offers a sleek and trendy design, but also safety for every cyclist. Whether you cycle through the city or on the most beautiful routes, our bicycle helmet is your reliable companion. The S-ERT helmet has integrated lighting all around. This can be operated in 3 positions: 1. Unit at the back on, 2. All-round lighting on, 3. Lighting off. Lighting on a bicycle helmet is essential for your safety, especially in low light or in the dark. It significantly increases your visibility, making you more likely to be noticed by other road users. The lighting in the helmet is rechargeable. The complete light unit is easy to remove from the helmet and the charging port is on the back. After charging, click the light unit back into the helmet. The light unit supplies the entire helmet with power, causing all (hidden) lights to illuminate. The lighting can burn for +-4 hours at a time. ERT stands for Energy Reduction Technology, an innovative technology specially designed to reduce impact and rotational forces in the event of a fall. Bicycle helmets made only of EPS mainly protect against direct, linear impact, but in the event of an accident, a rotational force is often released, which can be harmful to the brain. ERT helps absorb and disperse these forces, measurably reducing their impact. The blue ERT padding also has the positive addition that it ensures a very comfortable fit. Thanks to the magnetic effect of Fidlock, the closure can be opened and closed quickly and easily with one hand, even when wearing gloves, which is ideal while cycling. This reduces hassle with traditional buckles and significantly increases ease of use. In short: Equipped with ERT (Energy Reduction Technology), integrated and rechargeable lighting all around, sleek and molded design, 2 sizes: size M (54-58, 320gr) and size L (58-62, 350gr), 3 colors: concrete gray, matte black and midnight blue and a Fidlock magnetic closure.
