Thank you for viewing. This is a genuine Bridgestone Bikke cycle cover. It's a cover compatible with rear child seats. I purchased it online for around 6,000 yen, while the manufacturer's suggested retail price was 8,900 yen. I've used non-genuine covers before, but compared to the genuine one, the durability and fit were significantly inferior. Therefore, I've been using the genuine cover ever since and even had some in reserve. However, the bicycle itself has reached the end of its life, leaving only the cover remaining. I'd like to pass it on to someone who can use it. Thank you very much.
