If you going up any hills you are going to want the smallest motor sprocket you can get and the largest wheel sprocket. Go with #35 chain if you plan on abusing it at all. I had #25 on my mini bike and it would break every few rides.. For longest ride time you will want to go with brushless...

Awesome build!

bad arse build!

Check out hobbyking.com every day and around black Friday. And look at doing 2x 6s 16-20000mah batteries run in series. Or whatever you can find cheap to build up a 12s pack. HOBBYKING10 gives you another 10% off...

First time configuring a kelly. Any advise is most welcome! Anyone know if the foot throttle is 0-5 or 1-4v?

Thank you sir! Started on the battery wiring! Using 300amp 1/0GA welding connectors. (Very much overkill, but cheaper then Anderson) I was going to start with 8S and go from there but realized my contactor is 48v so going back to original plan of 12S and will limit the voltage via the...

Easy peasy. Race kart, Leaf/electric car batteries etek motor and a decent controller. Some motivation on what you can do. However, it will be much cheaper and easier to stick with 2stroke. :cheers2: https://endless-sphere.com/forums/viewtopic.php?f=34&t=68543...

Make sure you get the MX500 or MX650 (Full suspension) I have the Mx650 and ride the **** out of it. It is a blast for everyone from 6 year old kids to g'ma. Can easily fit another 12v 12ah battery for 48v. :cheers2: https://www.youtube.com/watch?v=dw3G_woEBlU

When does the 60v 2800w version come out? :cornut:

He is most likely running 22 of these for 72 +/- volts. @60ah http://www.evwest.com/catalog/product_info.php?products_id=179 Best thing to look for if you want a long lasting ev kart is batteries from an electric car that is being parted out. Batteries from the Nissan leaf seem to be the...

If you are making a rock crawler for your kid go with the 4x 350w motors (one at each wheel) Personally I would go with a single 1800w brushless setup unless you already have some motors lying around...

Bad Arse!

Chinese 24-60v YK43B. I bought mine on ebay new for 45$. Use it and upgrade to something fancier later if you need it.

If you want efficiency go with a 150A kelly. *They are overrated so figure the 150 will be good for about 100a. If you want raw power cheap go with the Chinese 24-60v YK43B. It supplies around 190a peak.

Post up some pics. And word to young is take anyone selling anything as full of sh1t and everything goes "60" and "Just needs the carbs cleaned". :)

Problem is the lb57 controller is for a 350w-500w motor. You need to feed your motors some power. Get a kelly KDS48200E or if you want to keep cost down and also have great power get the chinese YK43B 24-60v controller. Kelly controllers...

And two rattle cans of flat black. :)

Yes I get the math. And thank you for the correction on the brushless. :cheers2: However, I have DONE IT. And so have a ton of other people; successfully, multiple times with dozens of hours of operation. The video I posted the guy and his kid have been driving that kart around for 3 years...
