Default Re: bicycle motor vibration

I had some pretty substantial vibration at higher rpm's,,I made a front mount out of an 1 1/2" muffler clamp and welded the BGF mounting bracket with three holes in it to the clamp.Had to drill the holes bigger,,but now she is perfectly straight and solid as a rock,,only vibrates a little at WOT,,I dont suggest riding WOT on these chinese motors for much longer than 30 seconds or so,,unless you have a smaller sprocket on back or pulling a grade.Bad motor mounting like drilling a hole in the frame=Vibration!
