Im thinking of building this frame. I want to hang the 125cc 4speed lifan engine I was originally using in the WLA tribute build . Will the frame hold up or fold up.
I'm looking to build a light weight machine. The frame will use 1 inch tubing as backbone then between the backbones it'll use 1/2 inch tubing (kinda like a girder or truss) with no bottom tube. It'll have a swing arm that'll be a cross between a mtn bike and a motorcycle. Itll have a 16 in cycle tire on the rear and a 24 in bicycle tire for the front.
Respectfully, if you have to ask based off a scribbled picture maybe you should pick up a book on statics and metallurgy first and gloss over them before considering the task.
