79cc, Schwinn chopper 4g?

[Spare_Parts]

Getting ready to start collecting parts for the chopper build and not sure what transmission to get. 79cc engine is a must, not my decision. The bike has to pull from a stop without pedalling and would like to reach about 35mph.
So would the 4g be a good candidate for this application?

Don't see why not they are both 5/8" shaft, either that or CVT...........Curt
