Hello all. First Time pocket Biker, actually Pocket Biker Dad. Hoping to get the kids riding around the neighborhood on them. Reason I found this page was for information regarding a rebuild of with what I was told is a X1 Cateye. I will be posting on another thread for information regarding that but want to say thanks for everyones knowledge and help in my future projects. Hoping that more than one bike is in my future.
