24 volt 250w motor mounted not so sturdy on a bicycle frame. Ran it on half the voltage(12v) with a $20 tractor battery. Later you can see me changing the gear ratios with the shifter. This is important to gain speed without sacrificing acceleration. This was just a test if the old #25 chain could be put onto a 1/2"-3/16" bicycle sprocket. Seems not so great, but i will get a better motor mount and bicycle sprocket so it runs smoothly.
