Family Friendly VW
I started with a New Beetle Powerwheels which I bought for my daughter, she's a little small to be driving it yet anyway soI have some time to do some tinkering.
 

Here's the project as it now sits, I've cut out a substantial part of the structural plastic and suspension, and have greated a square tube frame for it. 
the rubber tires I used were much bigger than the plastic ones that were on it originally, I chose this size because it was the malles pneumatic tire I could find (on that particular day.), it fits within the fender alright and gives it a slightly beefire stance.
This is the motivation, two 24v wheelchair motors. they are powerfull suckers, I guess they dray a little too much current, because I smoked the speed control boards for them, so I'm contemplating a series-paralell relay setup, this would give only three speeds total, but is much cheaper to do than replacing the $400 control boards, and I'm much less likely to smoke it.
