How fast will it go mph

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 .

i bought a lithium ion battery with the xt60 connectors but this motor kit has rings. what do i do to change it?

Take out the fuse splice the wire to the type you want and Walla
