New Project - Electric Go Kart

[LeeNetworX]

We had some friends stay with us last week for the holiday and they brought their electric Razor drifting cart for their kids. The thing is awesome and I was extremely bummed that I was too big to ride it. However, the wife did and she loved it. She wanted to buy one for her and our boys (when they are older) but I told her no - I would build one for us and we can buy them a razor when they are old enough. Think we'll bypass the hopped up Power Wheels for them all together.

So I've been reading up on them and how different people have used different motors, controllers, etc. I know Derf said he built one in response to my FB post (even though he offered absolutely no details on the config he ran) but I was curious if anyone else here has done it?

I'm leaning towards a 36v golf cart or forklift motor and over-volting to 48v. Would use 4 deep cycle batteries. I've started keeping an eye on Craigslist and eBay for kart frames and used/rebuilt motors.

Check out some of these vids I found.

And on a related note, here's a guy that dropped an R1 engine on a go kart frame.
