Introduction: Petrol Engine in Power Wheels

About: Hello my name is Bob and I like to make things.

In this Instructable I show you how I motorised a Mini Cooper Power wheels electric children's car.

I do this using a 6.5HP Honda GX200 (clone)
They're perfect for motorising stuff ;-)

To make things more easy I used parts of an old mini quad. Those quads can often be found on the internet, since they're cheap and often break down.

Parts I used:

  • Electric Kids Car
  • 6.5HP Engine
  • Clutch
  • Quad parts
  • Steel to weld
  • Sprocket chain
  • brake / gas cable and controls

Step 1: Check Out My Video!

I hope this video will help you create a motorised children's car, or at least give you some inspiration for your own project. Along with the video I show you in the steps below how I dit it :-)

Of course it's hard to give a total blue print for the project. Because every power wheels is a bit different and so is every mini quad. But in general I show you the idea how easy it is to put a petrol engine in this little car.

Step 2: Collect the Parts

First I collected the parts.

I used an old electric 6v Mini Cooper.
It was a gift to my nephew a few years ago. But he never really enjoyed it because it's so slow.
Well it's not slow anymore ;-)

Then I got the wheels, steering and rear axle of a Chinese mini quad.

And the engine is a Honda gx200 (clone) with a centrifugal clutch.

Step 3: Measure and Fit Engine

I measure the electric car and give our creation the same wheelbase.

Then I weld the frame together and make holes for the engine.
I make the slots so that the engine is adjustable.

Now it can be aligned with the chain.

Step 4: Add Steering "wheel" and Controls

I mount the gas and brake control to the wheel. Since the car is so tiny I think that would be the safest way to control it.

Step 5: Fit the Body

Now it's time to see if the measurements are right and if the body will fit.
I attach some mountings and attach the body to the chassis.

Step 6: Finalising

Now some last finishings.

and very important, we need to top up the engine with oil.
Now some petrol in the tank and we're good to go!

Step 7: Enjoy :-)

If you make a 'toy' like this. Be very careful.

It might not be safe for children anymore (unsupervised).

But for the big boys (and girls) it's a lot of fun ;-)
