That's what we told our wives, anyway....BTW, our kids are only 2.5 & 3.5 years old. So, they won't be driving anytime soon. With the project cost justification taken care of, we bought Currie 36v 1000watt motors (http://tncscooters.com/index.php?route= ... uct_id=512)and 60volts, using 24v-60v speed controllers (http://tncscooters.com/index.php?route= ... uct_id=188). We got our inspiration from dmack's post here:http://forum.modifiedelectricscooters.com/viewtopic.php?f=10&t=1014. It was pretty simple to do with a just a little cutting and drilling and wiring, voila! Done.
Here's a quick and dirty temporary set up with the controller, (5) 12v7Ah batteries & motor strapped to the Kart:
We plan on cleaning it up a little. My neighbor welded a battery tray and plans to weld a bracket on to vertically mount the controller. We cut the motor/battery cover for use a chain guard so that little kids don't get their fingers caught.
Here's some crappy video of our first test ride after zip-tying every thing together. It's around midnight at the college near our houses. It seems like the only time we get to ride these things is at night after the kids go to bed:)
I'll try and post some better daytime pics/video later.
At 60v, these little go karts have some killer torque off the line. It will leave a 20+ft long black strip and actually leave smoke the tires! It will even pop the front wheels off the ground momentarily. They are a blast to rip around a parking lot doing slalom runs between concrete planters etc. Hell, we can even do a small, one revolution doughnut. The best thing about them is that we can easily pick them up and stick them in the trunks of our cars and head to a school yard or an empty parking lot.
The only problem is that the top end speed is a bit lacking at only 19.5-20 mph(gps) We are using the 11 tooth sprocket that came with the motor and the 32 tooth sprocket and the 4.5" wheels that came with the Kart.
We have 14 & 15 sprockets for the motor on order along with chain links and a chain tool. That should get us to maybe 23-25 mph.
We want to put larger diameter wheels and tires to get us a little more top-end speed and make better use of the available torque. Does anyone know of any other wheels that we can fit on these little Karts? I'd love to get a 6-7" wheel/tire set up on them.
