Purchased from Cycle Base Asahi. I used it for about a month, but I'm selling it because I no longer need it after buying a new bicycle. As shown in photo 6, there is a scratch on the right side. Overall, the condition is good, but it is still used, so there may be some dirt. Please purchase only if you understand this. All the necessary items for installation are included. The installation method is shown in Cycle Base Asahi's YouTube video, so please refer to that. Selling price: 9,790 yen (tax included) The following is quoted from the website: ○ Compatible child seats ・Panasonic Kroom Rear Seat (NCD458S/NCD459S) Premium Rear Child Seat (NCD450S/NCD453S/NCD454S/NCD480S) Comfort Child Seat (NCD366AS/NCD372AS/NCD471S/NCD472S) Casual Child Seat (NCD363AS/NCD475S) ・Yamaha Rear Child Seat Hug Seat (RBC-018DX2: Q5KOGGY04012/Q5KOGGY04013) Grandia Child Seat PLUS (RBC-017DX PLUS same model: Q5KOGG219466/Q5KOGG219473) Grandia Child Seat (RBC-017DX2 same model: Q5KOGG218391) Comfort Child Seat (RBC-011DX3 same model: Q5KOGGY04003/Q5KOGGY04004) Casual Child Seat (RBC-015DX same model: Q5KOGG208804/Q5KOGG208811/other colors) ・OGK KABUTO Grandia Child Seat PLUS (RBC-017DX PLUS) Grandia Child Seat (RBC-017DX2) Popola More Child Seat (RBC-019DX) Comfort Child Seat (RBC-011DX3) Casual Child Seat (RBC-015DX)
