Hey everyone, this is my first post. I have been into building motorized bikes for about 10 years off & on. I usually use Briggs motors. I did build one bike for a friend with one of the Chinese kits. Now I'm building one for myself and noticed some motors have a narrow front motor mount stud spacing & some motors have a wide (2'') front motor mount stud spacing . My question is does anyone sell just the motor alone with the wide spacing between the studs? Yes I know they make adapters for the narrower spaced motors to fit on larger front down tubes. Thanks & keep the shiny side up.
