### ⭐⭐⭐⭐⭐ かっこいい
*by 貧***ー on July 15, 2022*

最初はキツいかなと思いましたが、無事に自転車本体の接続完了付けてみてカッコイイと思いました。気分転換にもお勧めです

### ⭐⭐⭐⭐⭐ バッチリ
*by K***ー on May 24, 2021*

350ｍｍが欲しかったので、助かりました。良品でした。

### ⭐⭐⭐⭐ 男性陣のママチャリに！
*by T***I on June 25, 2022*

家内の電動ママチャリを借りる際に、あと少しサドルを上げたくて交換しました。家内が乗るときは下げてしまえば問題ないし、自分が乗るときはコレのお陰で適正な高さまで上がるので、膝が痛くならなくなりました。助かってます。
