My name is Tyler & all the 2 strokes are crap lol. The castings are poor. Engine pieces fall apart in your hands.


I’m looking for something small to fit in the cradle of my bicycle, so no on the Golden Eagle kits. The predator 79cc looks wider than the WhoShwang 49cc so I’m looking at that right now. Anyone know of anything (physically) smaller? I’d go w/ a larger bore as long as it’s more compact but I doubt that will happen.

Gx25 is about the smallest you can run but it’s gutless could go about 20mph perhaps. Gx35 would be better. Check out helio bikes they built an in frame gx35 setup and a eho35 in frame bike. I know there’s eho35 clones on eBay for $170. The smaller 4 strokes are rarely chaindrive though it’s mosty friction drive. Huasheng 49cc would be better though. Better yet get a gxh50 if you’re worried about Chinese engines like you said with the 2 strokes.
