OK i have the same question as well. I am a first time builder and i just got a new diamondback overdrive 29'er. there is 1 1/4 inch clearence from back of seat tube to the tire at the shortest place. the frame also is quite small. ARG I want to fit an 80/66cc motor as well as a SBP jackshaft kit. I'm in california too so so dang darn hard finding a seller at the right price. well, here's a pic and video PLEASE tell me if it'll fit, should i buy a kit then just see if it'll fit? if not buy another bike??? or what and also, jackshaft kit asks for seat tube size what if i get a different bike? well here's pic and here is video.
