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.
