So my grandson is running the wheels off his 12v powerwheels Jeep. The creative side of me started thinking that it would be cool to have a more durable version of the battery powered Jeep. Anyone built anything of the likes?

We used the motors out of an old emaxx (the brushed ones) and some pneumatic tires on one years and years ago for my nephew. It was a huge improvement over the original.

If you want to throw a gas motor in there, go kart would probably be a better choice. The powerwheels we had were independent drive left to right, and it would take some serious fabrication to make it all work.

You might be able to put the body on top of a chassis, then run a deeply geared governed motor with a centrifugal clutch.

That was my original thought...just not sure how to stuff the motor and such under the plastic. I might end up scrapping the jeep body and just make a pint size crawler.

I'm going from memory, but it seems like someone on the forum used the plastic outer shell from one of these electric-powered Jeeps and fitted it over a new frame with a gas-powered engine. Probably like a Predator 212. A centrifugal clutch would also simplify the engineering and build.

So, my guess is that it's doable, but will take some design work or prototyping to make it happen.

I added a small two stroke to my kids plastic quad.

It worked ok. The engine had a small gearbox reduction on it. I don't know what it was from.

I machined a hub to adapt a small sprocket to the plastic drive wheel and hung the engine on the back.

Was pretty funny watching it go with smoke coming out the back.

I probably have a pic somewhere, but the chances of me finding it are pretty slim.

This was back before everyone put pictures of everything they made on the interwebs.

Those little motors from the gas scooters were pretty good for transplants. They had a clutch and gear reduction, but the 35 series chain was pretty weak.

I started building one a couple years ago when I just felt like building something random one afternoon, this is as far as I got - it's just built on an old go kart chassis. 10hp briggs engine I had from an old SAE Mini Baja, CVT, exhaust is an old YZ250 silencer cut down... just never found motivation or desire to finish!

I have thought about using the electric motor setup that you see on the electric kids 4wheelers. Nice and small... and pretty good power.
