ONE BIKE HELMET – TWO GENERATIONS A modern and safe bike helmet that appeals to two generations at once. With the Youn-I 2.0 model, ABUS has successfully bridged the gap between adult and youth helmets. Adults are role models for children and should therefore also wear a bike helmet. This could prevent many of the serious brain injuries caused by cycling accidents. However, women with smaller heads often cannot find a helmet that fits them properly. With a simple but modern look, this bike helmet meets the needs of both young cyclists as well as many women with smaller heads. The Youn-I 2.0 boasts a simple, urban and fashionable look that appeals to both generations.
