i recently purchased one of these 49cc pocket bike motors and a cvt. im planning on putting this on an old mountain bike frame i have. im in the process of trying to get the gearing figured out but i cant find any info on the rpm's or Hp of this type of engine. does anyone know this info or where i can find it? and while im writing this post i have another question that im not to sure on. why is the target reduction 18:1. is this mainly for the ht motors or does this apply to all motors attached to bikes? thanks for any help.
