I actually already have a friction drive bike which i made with a ryobi 30cc grass scorpion whipper snipper ( no clutch ). I got this new motor 31cc Weed wasp at the tip for 5 bucks and spent about 20 on it to get new everything rubber as it was cracked and a new spark plug and many hours of cleaning, tuning the carby and cleaning the muffler. My friction drive is made of 30mm diameter knurled alu which ive covered in a JB Weld and sand mixture as the knurling wore off.
My new motor is going to be chain drive so im going to weld a 10T Sprocket to the clutch shaft ( it fits snug on ) and then going to go to a 50T sprocket mounted on a bike pedal hub thing and on the other side have another 10T sprocket then to another 50T on the wheel. These sprocket T are estimates, ruffly around those numbers, what ever i can find basically. The 10T sprockets i can get from the back gear changer on a mountain bike, it has 2 10T sprocket in there. The two 50T i can get from a bike shop or ebay. I may get one 50T or 60T on the hub and get a 44T HT sprocket from ebay for the wheel.
So the gearing is ruffly 10,60,10,44. That will give me some nice hill climbs and give me speeds of around 45-50km on the flats.
