The ABUS Urbanaut is one of the first helmets de-signed for E-bikers. The most important feature is the dual-compound in-mold shell, in which the EPS helmet material is molded in the outer shell. Thereby, another innovation comes into operation: The Multi-Density helmet material, which consists of two different components. This reduces the helmets volume and decreases the weight at an optimized impact protection. The ventilation is adjustable indi-vidually in the integrated ventilation ducts. Another positive safety feature is the rear light integrated in the adjustment wheel.
