Hi all,
First Post here.
I've done a little searching but couldn't find anything suitable, so may I please ask a question.
I am about to embark on my first build.
80/66c china girl engine kit
the bike is a 20 inch aluminum mountain bike I've had for years, in it's day it was very expensive, and is still a nice bike.
I'm reading a disturbing amount about the relative perils of frame mounting motors to aluminum frames, my down tube is 2 inch in diameter, so i'm going to have to fabricate some alternative to the standard mount. this in and of itself is not a problem, don't worry I'm not taking a drill to my nice bike.
But.
does anyone know of, or have any suggestions for decreasing the fatigue to my frame, I'm not at all convinced that putting rubber between the frame and the motor is going to reduce vibration, I'm no mechanic, but it seems to me that adding more material, particularly flexible material like rubber, only provides more "stuff to wobble".
I was wondering whether some kind of sleeve arrangement wrapping around down and seat tubes might be an option.
any wisdom would be most appreciated.
