    Smile Electric Go Kart

    Hi, Some pictures of an electric go kart that I made for my kids a year or so back.

    The kart has a welded steel frame and motor mount. It is a simple welding project and uses stock sizes of square tube section. My kids love driving it and the project has created lots of interest.

    We've set up a website with plans for the kart and lots of other useful information at

    If your looking for that next welding project have a look at our site. It is pretty easy to build a the kart and it out-performs any commercially available electric kids kart.

    Thank you for the comments.

    Yes, the kart has a 500W 36V MY1050 motor controlled by a 4QD speed controller. We used 3x12v 12Ah lead acid batteries - this gives about 1-2hours running time depending upon how hard the kart is driven. A chain drives the left rear wheel using mini-moto sprockets.

    We've found the 4QD controller to be an excellent device, it allows speed and acceleration ramps (both forwards and in reverse) to be set. This is pretty important for slowing the kart up for younger drivers. Unrestricted, the kart can do 12-15mph on a full charge. The accelerator pedal operates a bell pot that sets the speed of the kart. We fitted a battery condition monitor to give an indication of how much charge is left. The speed controller produces a regenerative braking effect that really slows the kart up. A disc brake is also fitted.

    We installed a separate lighting circuit. This powers the headlights and tail/brake light and a colour-change LED under the floorpan - night driving is great fun!
