Remember those power figures are Peak values !
If you want significant performance, i would look at one of the Cyclone drive motors...
...but then you would need a serious controller and battery :?
It quickly All gets very spendy !

I have tried that motor with a 17:1 gear reduction on a kids ATV, but I used a Kelly Kls Controller. A bit of overkill I know :lol:

But my brother wanted it to be powerful enough for himself also

Also the China chain is noisy as hell, I don't what it was, something like Tf#8 or whatever.

I got myself this motor: http://www.eastgem.net/d3000.html
or this kit: http://www.eastgem.net/d4500-k-1.html
with a #420 chain and sprocket, and it's not as loud and much tougher


These Motors only work with a square wave Controller though.

You can get yourself just the motor for 125 usd and a Sunwin Controller off ebay for 45 usd. I currently have that combo, and it's ten times better than that ebay motor for sure. Ofc you have to adapt a sprocket on to it, but that's about it.
