Power Wheel to Faster Pushy Car.




If you are a green thinker who hates to throw anything away, then this is a great afternoon project for those of us who have kids, a broken power wheel, and broken lawnmowers. This is still a work in progress to the finished "rally Jeep" my daughter wants, but she was absolutely thrilled just the same.

Step 1: Disasembly of Those Gas Wasting Old Machines You Have Laying Around.

I had my niece, and my oldest daughter do some junk dis assembly while I worked on some other passive solar greenhouse projects that i will submit at a later time as instructables.

Step 2: Disasemble the Electric Driveshaft From the Old Power Wheel.

I didn't take any pictures of this unfortunately, but here's the skinny:

Get your favorite electric screwdriver(phillips head) and go to town taking out the six or so screws holding the driveshaft to the frame. Once off, go ahead and cut out the wheel wells as you will need the extra clearance for the wheels not to rub.

Step 3: Install the Old Axle From the Junked Lawnmower.

As it states above, this is very easy, just get your rubber hammer out, and tap this right into place, getting it centered for good clearance inside the wheel wells, and for proper alignment of the back wheels. After getting the axle in place, add the rest of the hardware, bearings, and add the wheels.

Step 4: Go Out and Test Your Now Faster Soapbox Derby Style "Power Wheel."

Now is the time to test and tune so to speak. I was relatively lucky that my alignment was right on, and that the clearance was good. It was so much fun that my 12 year old niece had to take a few tries:) LAter this week we will be debadging, painting, and installing the braking system. BTW, I wouldn't suggest changing out the front tires to bike like tires due to the increase in "rollover" common to the real thing. So far, handling is great.

    It is an 84 VW rabbit GTI...so what's wrong with my blissful image of myself:)
    The car in the background was my rally cross race car. It is being sorta rebuilt right now from the inside out, and then repainted. You can view some images of me racing in it on myspace page: http://www.myspace.com/rallyboys

    just look at my photos if you are interested.

    OMG! You and T3hp... are funny! My backdrop would look like a few piles of crates, mulch, and scrap wood that mother nature continues to blow around! Thanks for making me laugh about the YUGO/VW thing!

    Does the power wheel (I'm assuming that is the pink jeep contraption) still power the back wheels, or is it a downhill machine only? If it powers the back wheel, how do you transfer the power from the motor?

    It is only a push car(derby style) for now, but I'm looking into picking up more broken kid's cars and lawnmowers to develop the concept a bit further. Essentially one could even make a pedal car out of one, but for now this one is a lightweight derby style speed machine. I will update this instructable once the brake assembly and finished body work is done.

    So is the push from behind? Maybe you could cut out the floor and make it Flintstones style! Also, instead of replacing the front tires, maybe attach rubber to add friction?

    Yep, for now we are using the roll bars that came standard as a push bar, but I will be fabricating an ergonomic push bar from those old lawnmowers possibly next weekend along with some other additions, a new paint job, and some decal work. If one were to cut out the floor, it would be very difficult for the younger ones to position themselves, as well as, it would add some unsafe elements.
