Review: Great little kit. - Nice little kit. Used this kit to convert a go kart to electric, run it off of 60 volt DeWalt batteries. Works great, all options work as they should. Reverse, brake lights, 3 speed switch, variable throttle, everything was good to go. Easy to wire, some labels are a little odd in translation from Chinese but pretty easy to figure out. Variable speed peddle is nice, controller can get a bit hot after an hour of continuous use andmay need a rest to cool off. Using the 3 speed setting switch 1st did 12.1 mph topspeed with a 60 tooth axle gear, I didn't use the gears or chain that came with the kit. I had #35 chains and sprockets as spares from other karts and used those so everything matched. Second I didn't pace or radar but I'd say probably 22-24 mph and third has to be pushing 40 mph with me in the kart. I'm about 200 lbs and this kit has no issues moving me around at a good clip. Kids love it, they get about 30-40 minutes out of a Dewalt 60 volt 3 ah (marked as a 9 ah but that uses 20 volt to get that rating) Figured the DeWalt batteries would work as I have several for my power tools and be easier for the kids to charge and swap out. And if buying some they are a lot cheaper then e-bike/e-scooter batteries.
Review: A+++ - So far so good fantastic motor beats the my1020 by Miles as far as torque and acceleration and Heat is not a problem get this over the silver one you will not be disappointed

## Questions & Answers

**Q: How fast will it go mph**
A: Dear Friend,
  1.The load speed is according to your wheel size , chainwhell teeth,and driver and scooter weight.
  2.but I can tell you the speed how to Calculate:  speed = bike wheel perimeter*RPM ( your chainwheel teeth /our motor 11teeth)*60/1000
  3.our motor rpm is 4300rpm and use 11teeth sprocket.

ex:  IF YOU USE 64Teeth plate.  so Gear Rato is : 64/11=5.8.
so,  rpm is4300/5.8= 740RPM.     if you use for 8inch wheel.
so the speed is : 0.2m(is wheel perimeter）*780*60/1000=28km/h  about .

**Q: This motor should be used only with lithium batteries? It does not work as lead, I have a brush motor scooter and it has lead batteries so the questio**
A: I see no reason why this would not work with lead-acid batteries.  I used it with a 48 volt, 1,000 watt power supply.

**Q: ?Need to reverse the polarity to run the motor in reverse.  I’ve switched a combination of two terminals, but still not getting the desired effect.**
A: You need to switch the yellow, blue and green cables. These are the cables that control the motor direction. It is actually trial and error.  This is the same as the front wheel motors.

**Q: i bought a lithium ion battery with the xt60 connectors but this motor kit has rings. what do i do to change it?**
A: Take out the fuse splice the wire to the type you want and Walla
