Sizing!! Will it fit? Please help

[alienboy366]

OK i have the same question as well. I am a first time builder and i just got a new diamondback overdrive 29'er. its a 22 inch frame but it's design makes it very hard for me to know if motor will fit or not. 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.

I feel your pain. I'm thinking about just buying the Grubee Skyhawk anyway and finding out for myself with my Raleigh M50dx. If it cant fit I might just buy a cheap schwinn cruiser from walmart. Good luck!
