The only reason it was done was because an engineering hot head told me it couldn't be done. Whats that? Oh, i DID strap a ginormous motor to the back of a BMX bike without hooking up the throttle control so i had to reach behind me to operate it....and it didn't have very good brakes...well i guess it was kinda dumb on my part, but no one was injured and i do not suggest doing it the way i did : )

On that note, I am thinking of going with a GX50 clone kit. I saw that there are kits that allow for this motor to be center mounted and rear mounted (both chain or belt driven) Any thoughts on which is better?
