I'm wondering if anyone has any thoughts on this. having had two jackshaft fail either due to a bad design or just having too much play and flex in the whole setup, I'm thinking about doing this. because using a 160cc engine that's geared for 24mph won't require pedalling. i'm thinking about taking the cranks off and using the pedal spindle as a jackshaft. this would require me to turn the rear wheel around in the frame and use a standard 36tooth sprocket on the rear. if the bottom bracket bearings ever fail I will press in either standard sealed bearings or I would add some pillow block bearings around the bottom bracket and use a standard jackshaft. I will add some pictures. does anyone have any thoughts on this.
