Hey I'm new here and I have a few questions about, and need some help with a tree speed motorized bike project I am working on
. I recently bought a three speed internally geared hub bicycle and am attempting to adapt an 80cc 2 stroke motor to drive the three speed hub on the right hand side of the bike, I bought an amazon jack shaft kit and tried to install it on the bike, and found out that the bb freewheel sprocket is for an 18 speed bb, so I am trying to figure that out. 
Any help or advice is apreciated! Thanks
