I made an electric car for my son

And I want to share a story and short built video with You. Car is electric, retro and build from... wood.

  • Introduction

    The car frame and sensitive body parts were made from.. wood. Yes, from wood. I used pine for the frame - it's ligth and flexible wood, good for such construction. More relevant parts like front suspension were made from oak which is hevier but also way stronger than the pine. If You are thinking that it is not good idea, bare in mind, that first cars were also made from wood. Anyway, after few months of driving my go cart by my son everything works perfectly fine.

    I choose the 24V 350W DC electric engine. It's enough for my son. I projected the whole thing to run with top speed about 9MPH. Engine RPMs was reduced by built in gears/transmission to 600 RPM and then with two other gears from motorcycles. To power the rear wheel I've used free-wheel to avoid back currents (ie. when riding down the hill). Such back currents could broke the engine controller. Controller is some cheap chinese device,

    I've used two 12V 18AH batteries. They last for 3-6hours of driving the car. Batteries are in the front of the car to balance the engine weight (which is on the rear).

    If You have more questons - I will answear them.

    Oh, important thing - the car is made mainly from wood and it's construction is very easy, so if You have time, workshop and kids - I recommend to build electric car for Your kids. It's not so hard and they will definitely have a real fun driving it.

    This is pretty amazing, good on you for putting something like this together for your kid! I wasn't able to find where you sourced the parts ie. engine, batteries, suspension. Just a local home depot? or something a bit more specialized?

      Looks like most are bike parts. As for the electric engine, maybe Radioshack?
