Re: hi everone new guy with some questions
The Madwagon is almost the perfect bike to be motorized (frame mount engine). It's made heavy and comes with strong MTB brakes.
A couple of things to watch-
The down tube looks oversized so you may need a to get front motor mount for oversized frame tubes or you can make one with a muffler clamp.
If that lower top tube interferes with the carb, you can alter your intake manifold by sawing it in half and use a heater hose to make a flexible section.
There are many posts on this site about both issues.
