Want Go-kart motor & electronics recommendation

Post by nickyg203 » Feb 24 2019 5:13am

I'm a high schooler looking to build a few electric go-karts over the summer for me and my buddies. I'm mainly curious if anybody has any motor recommendations that are moderately priced. We are hoping to spend around $500 all in; including materials to build the frames. Are the $200 motor and controller kits on eBay worth it or should I be looking at motors in the 3 or 4 horsepower range? I'm mostly mechanically oriented and have little to no knowledge on motors; aside from basic technical jargon. Any and all input will be greatly appreciated!

I recommend brushed motors for simplicity and this motor is cheap and easy to control with right controller.

If you would want a decent run time you need to spend a lot more per kart. The battery pack alone will cost more than $500 if you want to use some power for a reasonable time.

$500 might build the frame because you'll want to drive them on dirt where you won't get arrested which needs better hardware.

Easier/cheaper to build some electric BMX with single speeds and no pedals. The base bikes can sometimes be free. But its still going to cost $600-800 even with hunting for good deals.

Cheap, really?

Are you saying nothing cheaper would be worth recommending for kids mucking about with go-karts?

What would be a good controller to match that?

Is being able to reverse something special?

Yeah 500 is the whole budget, but you can run it without a controller...LOL

And it's double the horsepower... But to keep it in budget I would look for a used 1000w scooter on craigslist and soup it up.

Find the local scrap yard, and see if they have any older golf carts. Taylor-Dunns have a two horse continuous GE motor and a Curtis controller. You should be able to get the motor and controller for less than 50 bucks at scrap prices.
