I'm at work.... And this could fit in the bed of the truck.


I like the idea, but I think starting with a quad motor is the wrong way to go if you want a 4 wheel drive. Then again I am not big on the whole side by side craze.
I would use the front wheel drive car motor if you go 4wheel drive and build a small two seater. Out in the sand more power is more fun. I doubt you could build a single seat 4 wheel drive buggy light enough to make a quad motor fun. It would get around, but it would be slow.
Any idea which atv you would start with? Keeping it a single seater would definitely keep the weight and size down. Seems like their is a lot more metal in a cage enclosing you as opposed to a frame you straddle.
I think this guy has the right idea and would be what I would want to build. Probably a little much to tow behind your commuter, but I bet the blazer would handle it. Sounds like it is a little larger then you currently thinking and not as cheap, but looks like fun.

Transaxle /moon buggy.
Buy a honda motor/trans and toy axles.
Run 35-37 and go stupid places.

Not 4wd, but light weight, engine over rear axles... don't really need it to be.
Is It bad I would be willing to give it a ride? Dune party fun. 

I totally dig that atv tube buggy. I agree though, lose the handles, go steering wheel. Looks like a lot of tall weight in the back.
Design the top so it'll just keep rolling you right back on your wheels when you flip over. I'd dig that, something atv size, fully caged one seater, zoom zoom and who cares about flipping, put in a 5 point harness and a suspension seat![]()
