100% Shading, 99.99% Light Blocking, UPF50+ UV Cut Performance Achieved. OGK Genuine Bicycle Rear Child Seat Sunshade Newly Released.

OGK Giken Co., Ltd. (Headquarters: Higashiosaka City, Osaka Prefecture; Representative Director: Taiji Kimura), the domestic market leader in bicycle child seats (※1), will begin pre-sales of the OGK genuine bicycle rear child seat sunshade "Roof Air (UV-016R)" on its online store (https://ogk-giken.shop-pro.jp) starting May 13th, and gradually launch sales at bicycle retailers nationwide from May 21st. This product effectively blocks sunlight and UV rays by simply lowering the roof, suppressing temperature rise, and reducing stuffiness through its ventilation design. It aims to provide a more comfortable and safe environment for those who use child-carrying bicycles and contribute to heatstroke prevention.

**"Roof Series" catering to parents, with summer sales approximately doubling**

The "Roof Series," an all-weather roof-type rain cover developed based on feedback from parents, has received much praise for being "stress-free by simply lowering the roof," "significantly easier to put children in and take them out," and "easy to handle with a perfect fit due to its dedicated design," and sales have been strong. In particular, summer sales between July and September have grown year by year, expanding by 203% in 2025 compared to 2023, roughly doubling. On the other hand, concerns about temperature rise and stuffiness inside child seats during summer, as well as the risk of heatstroke, have been increasing. This product was developed in response to the growing demand for sunshade and heat protection measures in scorching summer conditions.

**Enhancing comfort with light blocking and ventilation, also coping with sudden weather changes**

"Roof Air" features a high-performance fabric with 100% shading, 99.99% light blocking, and UPF50+ UV cut performance (※2) widely placed on the top surface, thoroughly blocking strong sunlight and UV rays. By combining it with mesh fabric, ventilation is ensured, suppressing temperature rise and stuffiness inside the child seat, and preventing heat from accumulating in the child's body. Furthermore, dedicated attachment accessories for each child seat achieve smooth operation and a high degree of fit. In addition, a detachable transparent sheet, storable in a back pocket, is included to cope with sudden rain or wind.
