This is a rear child seat from OGK. I used it for about 2 years for my daughter, but I'm selling it because she's grown. It was stored in a covered bicycle parking area with a bicycle cover. It can still be used without any problems. ■ Casual Rear Kids Seat with Headrest ■ RBC-015DX (for rear) ■ OGK KABUSHIKI GAISHA ■ Instruction Manual You can check it from the following link. https://ogk.co.jp/manual/rear-childseat/RBC015DX__manu.pdf It was attached to an electric bicycle with a child seat.
