This is how I went about doing it! A 48v 500w rear hub motor and 66cc china girl and peddle power for a tri power hybrid! The 2 stroke engines output goes to a jack shaft and shifts the drive over to the right side and a 22t free wheel on the hub motor with a 12t ahead of it on the shaft and a 22t on the engine side!Then on the right side again there is a 16t free wheel on the shaft going forward to the peddle crank! Starting it requires kicking it over with the peddles but am now considering a bullet train electric start!These are the only pic I have of it right now but will take more when I work on it again,This bike is always just sitting in my back room and only gets worked on when I have time away from customer builds,repairs,and my other rides!
